Understanding Operations

Operations include deploying and undeploying service networks and creating policies that help to maintain optimal performance of your service network.

The following topics help you understand operations:

Logical Versus Physical Resources

Service Network and Logical Element States

Service Network Configuration

Operations Control

Logical Versus Physical Resources

In VFrame, you create service network templates, which are used to design service networks. The components that make up service network templates and service networks are called elements. Elements are logical representations of components and links within your service network. Elements are components, such as Firewall Services Modules, switches, server groups, links, ports, and so on.

Designing a service network is the process of assigning physical resources and defining specific information about the elements in the service network.

When you prepare a service network for deployment, you create logical elements. logical elements, such as logical servers, are devices that have been allocated, imaged, and configured, but have not yet been deployed.

When you deploy a service network, VFrame acquires physical resources to run the logical elements you have included in your service network. Physical resources are the actual devices that are configured to run your service network.

Service Network and Logical Element States

Table 14-2 describes operational states of service networks and their logical elements.

Table 14-2 Service Network and Logical Element States 

State
Description

Deployable

Service network must be in the Deployable state for any operation to be taken on the service network. When in this state, the service network has been successfully validated and is ready to be deployed.

At this point, you can either schedule to deploy or manually deploy the service network.

Acquiring Resources

A service network enters this state when attempting to gather the physical and logical resources it needs to run. As soon as it enters this state, the service network notifies all of its logical elements to also enter the Acquiring Resources state. Each logical element continues to reflect its own state during the acquisition process. When all logical elements have successfully acquired physical resources, the service network enters the Resources Acquired state; otherwise, it enters the Acquisition Failed state.

Resources Acquired

A logical element enters this state when VFrame successfully obtains all the physical and logical resources required for a particular logical element. It saves these mappings and places the logical element in the Resources Acquired state; otherwise, the logical element enters the Acquisition Failed state.

A service network enters this state when all essential logical elements have entered the Resources Acquired state. It is possible for a service network to enter the Resources Acquired state, while one of its logical elements remains in the Acquisition Failed state. This can happen when a particular logical element is not required for the service network to run.

The physical resources are now ready to be configured to run the service network. The service network automatically proceeds to the Configuring state.

Acquisition Failed

If a particular logical element fails to acquire the physical resources it needs, it enters the Acquisition Failed state. If this logical element is essential for the service network to function, the service network also enters the Acquisition Failed state. This can occur, for example, when the service network has only one logical element in it or when the failure of a logical element puts the number of logical elements of that type below the minimum required for the service network to function.

From this state, you can stop the service network. In addition, if a schedule is associated with the service network, and the time comes to stop the service network, the service network transitions to the Release state.

Configuring

A service network enters this state while configuring the physical resources to run the mapped logical elements. Each of the logical elements also enters a Configuring state.

Configured

The configuration generation failed for an element in a service network due to an application error, so the configuration is terminated. This state applies only to nonserver elements. You can undeploy the network from this state.

Configuration Failed

This state indicates a failure in configuring a physical resource to run its mapped logical element. The service network enters this state if any of its essential logical elements enters this state.

If the failed logical element is a server, you can stop the server without affecting the service network.

If the logical network is in this state, you can stop the service network.

Running

The service network and all its essential logical elements are in the Running state. It is possible for a service network to enter the Running state while a server remains in the Configuration Failed state.

Failure While Running

A service network in the Running state enters the Failure While Running state when it detects a fault in an essential logical element or when a verification operation returns a critical fault.

Service Network Element Error

(Servers only.) A server enters this state whenever it misses the specified number of consecutive heartbeats within the specified time frame.

For information about specifying server heartbeats and time frames, see Server Settings and Defining Server Settings.

Configuring (For Maintenance)

When you place any of the essential logical elements in maintenance mode, the logical element and service network enter the Configuring (For Maintenance) state.

Some logical elements require configuration of an associated physical resources in order for it to enter the Maintenance state. These logical elements have macros attached to them to perform configuration changes when a Maintenance event occurs. For example, a server might require an associated load balancer to be reconfigured not to direct traffic to it while it is in a Maintenance state. In this case, the load balancer enters the Configuring (For Maintenance) state.

If logical elements are successfully configured for maintenance, they, as well as the service network, enter the Maintenance state. The other resources that were configured for maintenance enter the Running state.

Maintenance

A service network enters a Maintenance state when any of the logical elements transition to the Maintenance state.

A scheduled operation (such as start, stop, or verify) has no affect on a service network in the Maintenance state. This prevents any maintenance operation from being interrupted.

Configuration (For Maintenance) Failed

A service network enters the Configuration (For Maintenance) Failed state whenever any of its essential logical elements enter this state.

You can stop or schedule to stop a service network when it is in this state.

Configuration (For Maintenance) Failed on Other

Some logical elements require configuration of an associated logical element in order for it to enter the Maintenance state. The logical element that initiates the Maintenance event is referred to as the source. The associated logical element that needs to be configured for the source logical element to enter the Maintenance state is referred to as the target.

A source logical element enters this state when configuration fails on its target logical elements. The target logical elements and the service network enter the Configuration (For Maintenance) Failed on Element state.

To clear this state, do one of the following:

Clear the status of the error: Select the logical element, the Configuration tab, and then the error, and then click Clear Status. The logical element and service network go back to their previous states.

Stop the network.

Configuration (For Maintenance) Failed on Element

Some logical elements require configuration of another logical element in order for it to enter the Maintenance state. The logical element that initiates the Maintenance event is referred to as the source. The other logical element is referred to as the target.

A target logical element enters this state when it fails to be configured for maintenance.

To clear this state, do one of the following:

Clear the status of the error: Select the logical element, the Configuration tab, and then the error. Then click Clear Status. The logical element and service network go back to their previous states.

Stop the network.

Configuring (For Exiting Maintenance)

A service network enters this state when any of its essential logical elements enter this state. A logical element enters this state when it needs to make configuration changes on an associated physical resource to return it to a Running state. Logical elements that do not require this type of configuration change skip this state.

When a service network or logical element successfully completes the configuration changes necessary to resume operation, it returns to the Running state.

Configuration (For Exiting Maintenance) Failed

A service network enters this state when any of its essential logical elements enters this state.

You can stop or schedule to stop a service network when it is in this state.

Configuration (For Exiting Maintenance) Failed on Other

Some logical elements require configuration of another logical element in order for it to exit the Maintenance state. The logical element that initiates Exit Maintenance event is referred to as the source. The logical element that needs to be configured for the source logical element to exit the Maintenance state is referred to as the target.

A source logical element enters this state when configuration fails on target logical elements. The target logical elements and the service network enter the Configuration (For Exiting Maintenance) Failed on Element state.

To clear this state, do one of the following:

Clear the status of the error: Select the logical element, the Configuration tab, and then the error, and then click Clear Status. The logical element and service network go back to their previous states.

Stop the network.

Configuration (For Exiting Maintenance) Failed on Element

A logical element enters this state when it fails to be configured for exiting maintenance.

To clear this state, do one of the following:

Clear the status of the error: Select the logical element, the Configuration tab, and then the error, and then click Clear Status. The logical element and service network go back to their previous states.

Stop the network.

Configuring (For Incremental Change)

A service network enters this state whenever an incremental change needs to be made to any of its essential logical elements. For example, a load balancer configuration might need to be changed when a server is added to the service network. In this case, the load balancer and the service network enter the Configuring (For Incremental Change) state.

When a service network or logical element successfully completes the configuration changes necessary for incremental change, it returns to the Running state.

Configuration (For Incremental Change) Failed

A service network enters this state when any of its essential logical elements enters this state.

You can stop or schedule to stop a service network when it is in this state.

Configuring (For Server Start)

A logical element enters this state when a Start Server event triggers configuration macros to be run on it.

Server Start Failed

(Servers only.) A server enters this state after it is successfully acquired and configured, but it or the logical elements surrounding it fail to be configured successfully.

Configuration (For Server Start) Failed

A logical element enters this state after entering the Configuring (For Server Start) state and failing to be successfully configured.

Removing Configuration (For Server Stop)

A logical element enters this state after entering the ConfigFailedForServerState state and receiving a Stop Server event.

Removing Configuration (For Server Stop) Failed

A logical element enters this state after entering the Removing Configuration (For Server Stop) state and failing to remove its configuration. If successful, it enters the Running state.

Server Initiated Maintenance

(Windows servers only.) A Windows server enters this state when it reboots. After successfully rebooting, it enters the Running state.

Removing Configuration

A service network enters this state when a user or schedule stops the service network from a Running or Maintenance state. Each of its logical elements also enters the Removing Configuration state while it removes any configuration that was done to set up the logical element on the physical resource.

Completed Removing Configuration

A logical element enters this state after successfully removing any configuration that was done to set up the logical element on the physical resource.

A service network enters this state when all logical elements have entered this state.

Removing Configuration Failed

A logical element enters this state when it is unsuccessful at removing any configuration that was done to set up the logical element on the physical resource.

A service network enters this state when all logical elements have entered this state.

Removing Configuration (Due To Error)

A logical element enters this state when it experiences a failure or an error, and then VFrame issues a Undeploy Network event or you manually stop the network.

Completed Removing Configuration (Due To Error) Failed

A logical element enters this state after entering the Removing Configuration (Due To Error) state and failing to remove its configuration.

Completed Removing Configuration (Due To Error)

A logical element enters this state after entering the Removing Configuration (Due To Error) state and successfully removing its configuration.

Releasing Resources

A service network enters the Releasing Resources state when all of its logical elements have entered the Completed Removing Configuration state. When this happens, all resources associated with the logical elements are released, and consequently, they also transition to an appropriate release state.

Logical elements enter this state while releasing all their associated physical and logical resources.

Releasing (Due To Error)

A service network enters this state in any of the following situations:

A user or schedule stops the service network from an error state, such as Failed, Configuration Failed, or Configuring (For Incremental Change) Failed.

Any of its logical elements enters the Removing Configuration Failed state.

When either of these situations happen, all physical resources associated with the logical elements are released in error, and consequently, they also transition to the ReleaseDueToError state.

A logical element enters this state when it is stopped either manually or at a scheduled time while it is in a configuration error state. The Releasing (Due To Error) state implies that VFrame was unable to remove completely the configuration from the physical resource.

Deployment Blocked

A service network enters this state if any of its essential logical elements enter this state. In this case, the service network releases all logical elements and physical resources.

You cannot deploy a service network when it is in this state; however, you can configure VFrame to ignore errors and transition to the Deployable state. You can also fix the errors on affected logical elements, which prompts the logical elements to transition to the Deployable state and the service network to transition to the Deployable state.


Service Network Configuration

When a configuration change is made, VFrame captures the configuration of the physical resource before and after the change. VFrame maintains a limited number of configurations, and older configurations are removed when new ones are uploaded.

If the device configuration uploaded before and after a configuration state change is made, you can view the difference in the device configuration caused by the VFrame action. You can also view the latest configuration of a physical resource if VFrame is the only management application configuring the physical resource.

Service Network Verification

Service network verification compares the initial configuration that VFrame deployed with the configuration running on the device. Verification checks all system-defined configuration changes and any user-defined macros that are associated with Verify events.

Any changes are reported as errors. If you want errors to be automatically corrected, select the Auto Correct Detected Changes option. This applies to all system actions and any user-defined macros that are designed with the capability to perform corrections. For more information about designing macros to perform auto correction, see Macro Design Concepts, page 11-9.

Operations Control

VFrame enables you to control the operation of your service network and the elements within it. You can schedule when to deploy or undeploy a service network, set the server count, and set up policies that specify when or under what conditions to start or stop a server. You can also configure e-mail notifications if faults of a specific priority level are logged.

VFrame uses the management VLAN to stop service networks and servers. So, it is important to have the management VLAN set up properly.

The following topics provide detailed information about controlling operations:

Scheduled Operations

Network Settings

Server Group Policies

Monitoring and Trend Policies

Notifications and Alarms

Scheduled Operations

Scheduled operations are start, stop, and verification operations that occur at defined times for the opened service network. You can specify what time the operation should occur and whether it should be repeated.

For information about configuring these settings, see Scheduling Operations.

Network Settings

You can define a network setting, which affects all devices in your service network.

You can choose to upload device configuration settings after a configuration operation has completed. This information is used in the Diff operation to compare configuration settings before and after a configuration change.

For information about configuring this settings, see Defining Network Settings.

Server Group Policies

Server group policies maintain an optimum number of servers for your service network at any given time. These policies provide the following information:

Server Settings

Server Count

Load-Based Rules

Monitoring and Trend Policies

Server Settings

You specify server settings to tell VFrame the number of minutes to allow for a server to boot. You can also set the number of consecutive heartbeats to allow a server to miss before VFrame marks a server as failed and remaps it to a different physical server and the number of times a server may fail within a specific time frame before the server is marked in error. This failure count is for logical servers, not physical servers.

Remapping occurs when a logical server is successfully started, and then fails while it is in the Running state. VFrame stops the failed logical server and starts the same logical server on a different physical server. If an error occurs while while the logical server is attempting to start, it enters the Configuration Failed state until you stop the logical server or the service network.

For information about configuring these settings, see Defining Server Settings.

Server Count

You can configure a default server count, which is in effect whenever the service network is running and no other rule is in effect. You can also create server count rules that specify the maximum, minimum, and target number of servers for a service network during specified times.

VFrame applies the first server count rule that matches the current time. If none match, it applies the default server count settings.

The maximum, minimum, and target number of servers are defined as follows:

Maximum—The network must not have more than the maximum number of servers running. If the running server count is above the maximum number, VFrame logs an error and tries to stop enough servers to bring the count down to the maximum number.

Minimum—The network must have at least the minimum number of servers running. If the running server count falls below this number, VFrame logs an alarm and tries to start enough servers to bring the count back up to the minimum number.

Target—The network should have at least the target number of server running. If the running server count falls below the target number, VFrame logs a warning and tries to start enough servers to bring the count back up to the target number. If the running server count is above the target number, no action is taken.

When applying server counts, if the server count is below the target number, VFrame starts as many servers as needed to bring the count up to the target number. However, if the server count is above the target number, VFrame functions differently. VFrame stops servers only if the count is above the maximum number, and it stops only enough servers to bring the server count down to the maximum number, not to the target number.


Note The default server count is not in effect when a service network is in maintenance mode.


For information about configuring these settings, see Defining Server Count.

Load-Based Rules

Load-based rules specify thresholds for average memory and CPU utilization during specified times. They also define what action VFrame should take if one of those thresholds is exceeded. The actions are to start or stop a server.

For time- and load-based rules, VFrame evaluates all policies that match. Then it performs the action that has the most matches. For example, if six rules match with start server actions and three rules match with stop server actions, VFrame starts one server, because there are more matches with start server actions.

VFrame waits the number of minutes you specify in the default load-based rules settings whenever repeating an identical load rule action because rules matched. So, if VFrame already started one server based on a load rule, it will wait the number of minutes indicated before starting another server based on load rules.


Note The wait time is the minimum interval between two load-based actions of the same type (for example, both server start or server stop actions). It does not matter whether the same rules applied in both cases or not.


You can define load-based policies to monitor memory or CPU usage and start another server whenever the percentage of usage for any number of running servers exceeds the percentage indicated for the number of monitoring intervals specified. For example, you can set the CPU usage to 90 percent for three servers for five monitoring intervals. If VFrame finds that the CPU usage for three servers is at 90 percent or greater for five monitoring intervals, it adds a server.

Similarly, you can define load-based policies to monitor memory or CPU usage and stop a running server whenever the percentage of usage for any number of running servers falls below the percentage indicated for the specified number of monitoring intervals. For example, you can set the CPU usage to 20 percent for two servers for five monitoring intervals. If VFrame finds that the CPU usage for two servers is at or below 20 percent for five monitoring intervals, it will stop a running server.

Similar to default policies, when VFrame adds a server, the same constraints apply. VFrame can only start another server if one is allocated and available. A server is started based on load rules only if the running server count is below the maximum number, and a server is stopped based on load rules only if the running server count is above the target number.

For information about configuring these settings, see Defining Load-Based Rules.

Monitoring and Trend Policies

Monitoring and trend policies define time intervals for VFrame to poll servers in the selected server group for specified data. You specify the type of data, which is grouped into these four categories: system, interface, HBA ports, and NFS statistics.

Valid polling intervals are between 1 minute and 2 hours. Data is used to generate logical server trend reports. For details, see Generating Logical Server Trend Reports, page 16-8.

For information about configuring these settings, see Defining Monitoring and Trend Policies.

Notifications and Alarms

VFrame defines several fault state machines to track the status of various types of resources, both virtual and physical. In operations, you manage fault state machines for logical elements. For information about managing fault state machines for physical resources, see Managing Fault Alarms, page 15-1.

Each fault state machine includes a set of states. Whenever a resource enters or leaves a state, VFrame issues a fault alarm. You can configure the fault alarm to be one of four priority levels: fatal, error, warning, and informational. For each level, you can also configure e-mail notifications to be sent out. For details about setting fault alarm priority and e-mail notifications, see Defining Notifications for Alarms.

Notification settings specified for a service network automatically apply to all logical elements within the service network. For example, if you set an e-mail notification for faults with an Info priority level at the network level, whenever any of the logical elements log a fault with Info priority level, e-mail notifications are sent.

Operating a Service Network—Scenario

This scenario builds upon the service network template you created in Chapter 11, "Designing Templates" and the service network you designed in "Designing Service Networks." The template is based on a sample network design in which you have a switch with a CSM connected in single subnet (bridge) mode to a group of servers, as shown in Figure 11-11.

This scenario assumes that the VFrame administrator has already completed all of the prerequisites for creating a service network template and created the CSM service network template. For details on these prerequisites, see Creating a Service Network Template—Scenario, page 11-42. In addition, the default service network policies will be used for this scenario. For details about service network policies, see Operations Control.

This scenario assumes that you have done the following:

Created the CSM template as described in Creating a Service Network Template—Scenario, page 11-42.

Created the CSM service network as described in "Designing Service Networks."

This scenario shows you how to:

Configure Your Servers

Test Your Service Network

Deploy Your Service Network

Monitor and Maintain Your Service Network

Configure Your Servers

In order to run your service network, you need to create and image your servers. This scenario assumes you are using NFS storage, so LUN paths do not need to be defined.

Before You Begin

Make sure the state of the service network is Deployable.

Procedure


Step 1 Select Operations > Operations.

Step 2 Open the desired service network.

Step 3 From the Opened Service Network selector, right-click the desired server group element and select Create Servers.

Step 4 In the Number of Logical servers field, enter the number of servers to create and click OK. For this scenario, enter 3 as the number of server.

As the servers are created, their names and states appear below the server group, and they enter the Ready For Imaging state.

Step 5 Right-click the first server and select Image Servers. Repeat this step for each server.


Tip To select multiple servers, select the first server, and then hold down the Shift key while selecting additional servers. To image multiple servers, click the Actions drop-down menu and select Image Servers.


After the servers are imaged, they enter the Deployable state.


Test Your Service Network

Before you deploy your service network, it is a good idea to perform a test run. Doing a test run starts virtual tasks without actually acquiring or configuring resources.

Before You Begin

Make sure the state of the service network is Deployable.

Procedure


Step 1 Select Operations > Operations.

Step 2 From the Service Networks selector, select the desired service network and click Deploy.

Step 3 Click the Dry run radio button and click OK.

Step 4 Review the information in the following tabs for information about your test:

Logs tab—Displays log entries for every operation that VFrame performed for the opened service network. For detailed reference information, see Logs Tab.

Acquired Resources tab—Displays resources, such as devices and IP addresses, that have been acquired for your service network.

Verification Results tab—Displays details about the verification operation actions performed for the opened service network. For detailed reference information, see Verification Results Tab.

Configuration Results tab—Displays details about the configuration operation actions performed for the opened service network. For detailed reference information, see Configuration Results Tab.

Faults tab—Displays details about the faults detected by your service network. For detailed reference information, see Alarms Tab.

Step 5 Correct any errors and rerun the test until you are confident in the results.


Deploy Your Service Network

After you have configured and tested your service network, you can deploy your service network.

Before You Begin

Make sure the state of the service network is Deployable.

Procedure


Step 1 Select Operations > Operations.

Step 2 From the Service Networks selector, select the desired service network and click Deploy.

Step 3 Click the Run deployment now radio button.

Step 4 Optionally, you can also select the Stop on Error check box. If a configuration error occurs during startup, an error is generated and the network is stopped. Left unchecked, the network continues to run while in the error state so that you can locate and correct the error. In order to implement the correction, you must undeploy and redeploy the network.

Step 5 Click OK.


Monitor and Maintain Your Service Network

After your service network has been deployed successfully, you need to monitor it to make sure that it continues to operate as expected. You might also need to perform maintenance operations, such as upgrading device OS versions, replacing failing devices, or placing logical servers in Maintenance mode.

Following are some suggestions for monitoring and maintaining your service network:

Periodically review the alarms status. You can display details about the alarms detected by your service network in the Alarms tab. From the Operations Tab, select a service network and click the Alarms tab. For detailed reference information, see Alarms Tab.

Set up automatic e-mail notifications for alarms. Alarms and notifications are defined separately; however, they work together. When an alarm reaches a specified severity, a notification can be sent to a recipient via e-mail.

You can configure e-mail notifications for alarms based on the alarm severity. Although each alarm has a default severity, you can modify the severity to suit your notification requirements; changing the severity does not affect how the system responds to the faults. For details on setting up automatic e-mail notifications for alarms, see Defining Alarms and Defining Notifications for Alarms.

Periodically review the Verification Results tab. You can display details about the verification operations performed for the service network. From the Operations Tab, select a service network and click the Verification Results tab. For detailed reference information, see Verification Results Tab.

When necessary, launch the device manager of a particular device to determine its status or troubleshoot a problem. Depending on your location in VFrame, you can launch a device manager for a physical device or a logical server:

To launch a device manager to access the physical device, from the Resources or Pools tab, right-click a device and select Device Manager. Then choose an external program to connect to the device. For example, you could start an SSH client session with a Catalyst switch.

To launch a device manager to access a logical server, from the Operations tab, right-click a logical server and select Device Manager. Then choose an external program to connect to the logical server. For example, you could start a telnet session with a Windows server.


Note Before you can use the Device Manager command, you must configure the applications that users can select from. For details, see Configuring Device Managers, page 18-9.


Perform regular maintenance on physical devices in your service network. During normal network operation, you might need to perform maintenance tasks on the physical devices in your network. For example, you might need to upgrade (or downgrade) the OS version of a switch or server or replace defective service modules (FWSM, CSM). However before beginning, it is important that you understand how maintenance tasks can affect the physical devices in your network now that VFrame manages them. For detailed information, see "Maintaining Devices."

Troubleshooting Operations

These are some problems you might have with operations and their solutions:

Deployment fails due to wrong gateway IP address assignment.

Verification fails on the FWSM standby unit.

Users do not receive e-mail notifications for fault alarms.

Service network starts and stops at unexpected times.

The Diff report (obtained by clicking the Diff button on the Configuration Results and Verification results tabs) contains no comparison data.

Servers start but VFrame logs them as failed.

Server count is not what is expected.

VFrame attempts to start a server due to a load-based rule, but the server start fails, and VFrame does not attempt to start another server.

VFrame logs fault alarms when acting on a new server count rule.

Server acquisition fails.

VFrame cannot start servers due to DHCP server timeouts.

Problem   Deployment fails due to wrong gateway IP address assignment.

Solution   You must correct the gateway IP address assignment and redeploy the service network. To do so, delete the servers that you have created. From the Operations tab, right-click the desired server and select Delete Servers. Next, correct the gateway IP address. Select Service Networks > Block Variables and enter the correct gateway IP address. Create and image servers and redeploy the service network.

Problem   Verification fails on the FWSM standby unit.

Solution   VFrame detected configuration differences between the standby unit and the active unit. If you did not make any manual changes to the standby unit, you can resynchronize the configurations by entering the write standby command from the active unit. This command writes the configuration from the active unit to the standby unit.

Problem   Users do not receive e-mail notifications for fault alarms.

Solution   If you configured notification settings for a fault state machine, and a fault alarm occurred that should have generated an e-mail but did not, the problem is probably that the SMTP settings for VFrame are not configured correctly. Select File > System Settings, and then the SMTP tab. Ensure that a valid, existing e-mail address and SMTP server are specified. Click Test Settings to verify that VFrame can use the account.

Problem   Service network starts and stops at unexpected times.

Solution   VFrame does not prevent you from scheduling conflicting start and stop rules for your service network. For example, you could create a rule to start the network at 10:00 a.m., repeating every 6 hours and another rule to stop the network at 11:00 a.m., repeating every 5 hours. At some point, these rules will collide, and the result will be unexpected starting and stopping of your network. To avoid this problem, start and stop network rules should have the same repeat time intervals.

Problem   The Diff report (obtained by clicking the Diff button on the Configuration Results and Verification results tabs) contains no comparison data.

Solution   In order for the Diff report to show comparison data, you need to configure VFrame to upload the device configuration when deploying a service network. From the Operations tab, open the service network and click Policies. Select the Network Settings tab and the Upload Device Configuration check box.

Problem   Servers start but VFrame logs them as failed.

Solution   The time required for the servers to boot might be longer than the timeout set in VFrame. Check the DHCP server and server boot-up settings. From the Operations tab, open the service network and click Policies. Select the server group logical element and click the Server Settings tab.

Problem   Server count is not what is expected.

Solution   VFrame does not prevent you from creating overlapping server count rules for your service network. For example, you could create the following rules:

Rule 1: Daily starting at 5:00 AM for 12 hours, set server count to Target = 5, Minimum = 3, and Maximum = no limit

Rule 2: Daily starting at 10:00 AM for 2 hours, set server count to Target = 8, Minimum = 5, and Maximum = no limit

Each monitoring interval (set in the Monitoring/Trend tab), VFrame checks the rules to determine if any action is necessary, and acts on the first rule that it matches. Because VFrame analyzes the first rule and finds a match, the second rule will never be acted upon.

Check that your server count rules do not overlap. From the Operations tab, open the service network and click Policies. Select the server group and click the Server Count tab.

Problem   VFrame attempts to start a server due to a load-based rule, but the server start fails, and VFrame does not attempt to start another server.

Solution   If server start fails, VFrame waits the number of minutes indicated by the monitoring interval before attempting to start another server. To check or change the monitoring interval, from the Operations tab, open the service network and click Policies. Select the server group and click the Monitoring/Trend tab.

Problem   VFrame logs fault alarms when acting on a new server count rule.

Solution   If the number of running servers exceeds the new server count rule, fault alarms are logged. To avoid this, you can adjust the minimum or maximum number of servers to be within the range of the previous rule or you can create an interim server count rule that specifies the new target number of servers as the previous minimum number of servers.

For example, you have the following server count rules:

Rule 1: Daily starting at 5:00 AM for 12 hours, set server count to Target = 5, Minimum = 3, and Maximum = no limit

Rule 2: Daily starting at 5:00 PM for 12 hours, set server count to Target = 10, Minimum = 8, and Maximum = no limit

When VFrame transitions from rule 1 to rule 2, fault alarms will be logged because, based on the new rule, the service network is running with 5 servers, which is below 8 servers (the new minimum number of servers specified). To prevent unnecessary fault alarms, you can change minimum number of servers in rule 2 to be 5 servers. Alternatively, you can create a new rule that sets the minimum number of servers to 5 to be in effect temporarily, until VFrame can start enough servers to reach the new target.

Problem   Server acquisition fails.

Solution   One possibility is that VFrame cannot find a server that matches the requirements specified in Service Network Design. Make sure that you specified the correct requirements or contact your network administrator to determine if servers can be added that match your needs.

Another possibility is that all server resources in the specified pool are in use. You will need to wait until these resources are released before your service network is able to acquire servers.

Problem   VFrame cannot start servers due to DHCP server timeouts.

Solution   Check the following:

The time required for the servers to boot might be longer than the timeout set in VFrame. Check the DHCP server settings. From the Operations tab, open the service network and click Policies. Select the server group logical element and click the Server Settings tab.

Make sure that the IP helper is configured on the SVI interface if VFrame is not in the same subnet as the server.

Verify that VFrame has a route to the subnet or that the VFrame default route can reach the subnet.

Make sure that spanningtree PortFast is enabled on the server connected to the switch port.

Logical Server Fault State Machines

The logical server fault state machines relate to your virtual application servers. You can configure fault severity, which is the severity level of the fault generated by changes to this state. This configuration affects the severity displayed in the interface, and is what controls when notifications are sent based on your notification settings. For details, see Defining Alarms.

Table 14-25 explains the logical server fault state machines.

Table 14-25 Logical Server Fault State Machines 

Fault State Machine
Description and States
LN Server (Logical Network Server)

Fault state machines related to virtual application servers.

Configuration Server

Indicates the state of the server. For a complete description of these states, see Table 14-2.

Health

Indicates the health of a logical server. A logical server is considered unhealthy if it repeatedly fails too frequently (for example, misses heartbeats or repeatedly goes into a Failure While Running state). This might indicate a problem with the image.

By default, if the same logical server misses a heartbeat three times in one hour, it is considered unhealthy, and it goes into a Service Network Element Error state. When this happens, VFrame no longer tries to remap that logical server. When the affected logical server (or the service network) is stopped, the logical server enters a Deployment Blocked state and remain in this state until you acknowledge and clear it.

OK—Logical server is in good health.

Bad—Logical server missed too many heartbeats within a specified time range. The time range is specified in the Server Settings tab (Operations > Operations > Policies > ServerGroup > Server Settings).

Heartbeat

Indicates whether VFrame is receiving regular heartbeats from the server while it is running. The heartbeat interval is specified under Operations > Operations > Policies > ServerGroup > Monitoring/Trend. The default is once per minute.

OK—VFrame is receiving heartbeats; the server is up and running

Missed—VFrame missed the number of heartbeats specified in the Server Settings tab (Operations > Operations > Policies > ServerGroup > Server Settings). The default is three heartbeats. If VFrame misses three consecutive heartbeats from a server in the selected server group, this fault state machine enters a Missed state. When this happens, the running logical server enters a Failure While Running state, and the logical server is stopped and started again on a different physical server.

Verification

Checks that the device configuration is that which was configured by VFrame and reports the outcome.

OK—Verification did not detect any configuration changes.

Warning—Verification detected a configuration change on a logical server (or one of its child nodes), which might not cause a network failure.

Partial Error—Verification did not detect any configuration changes on the logical server; however, it did detect one or more configuration changes on one of its child nodes, which might cause a network failure.

Error—Verification detected a configuration change that might cause network failure.

Logical Server Group

Fault state machines related to virtual application server groups.

Server Count

Indicates how the number of running logical servers compares to the number specified in the Server Count tab (Policies > Server Group > Server Count).

Over Target—VFrame detected more running servers than the target number specified. This condition is not considered to be an error. The servers will continue to run.

OK—VFrame detected the specified number of servers running.

Below Target—VFrame detected fewer running servers than the target number specified or VFrame detected the exact number or fewer running servers than the minimum number specified. This condition is a minor error, and VFrame will try to bring up additional logical servers until the running number of servers reaches the specified target count.

Below Minimum—VFrame detected fewer running servers than the minimum number of servers specified. This condition produces an error, and VFrame will try to start additional logical servers until the running number of servers reaches the specified target count.

Over Maximum—VFrame detected more running servers than the maximum number of servers specified. This condition produces an error, and VFrame will try to stop running servers until the running number of servers reaches the maximum number of servers specified.

Verification

Checks that the device configuration is that which was configured by VFrame and reports the outcome.

OK—Verification did not detect any configuration changes.

Warning—Verification detected a configuration change on a logical server (or one of its child nodes), which might not cause a network failure.

Partial Error—Verification did not detect any configuration changes on the logical server; however, it did detect one or more configuration changes on one of its child nodes, which might cause a network failure.

Error—Verification detected a configuration change that might cause network failure.


Logical Network Fault State Machines

The logical network fault state machines relate to your virtual Ethernet switches. You can configure fault severity, which is the severity level of the fault generated by changes to this state. This configuration affects the severity displayed in the interface, and is what controls when notifications are sent based on your notification settings. For details, see Defining Alarms.

Device OS Version Change

Compares the current OS version of an acquired physical resource with the OS version that was on the device when VFrame configured it (when the network was started) and reports the results:

No change—No device OS version change detected.

Change—Device OS version change detected.


Logical Storage Fault State Machines

The logical storage fault state machines relate to your virtual storage devices, such as storage area network (SAN) equipment and NFS filers.You can configure fault severity, which is the severity level of the fault generated by changes to this state. This configuration affects the severity displayed in the interface, and is what controls when notifications are sent based on your notification settings. For details, see Defining Alarms.
