The descriptions in this chapter use only a part of the functionality offered by the Virtual Server Group menu. To create virtual server groups or add virtual servers to a virtual server group, see Chapter 11, "Creating Virtual Server Groups."
Locating the Virtual Server Group Menu
To locate the Virtual Server Group menu, follow these steps:
Step 1 Launch VFrame Director, if it is not already open.
Step 2 Click the + next to the VFrame site icon.
Step 3 Click Virtual Server Groups folder in the left menu.
You can navigate the Virtual Server Group menu through the Summary window, or you can navigate the Virtual Server Group menu through the navigation tree.
Viewing and Using Virtual Server Group Summary Information
The Virtual Server Group Summary window allows you to view virtual server groups and their associated virtual servers at a glance, as well as perform actions that pertain to virtual server groups and virtual servers.
A virtual server group is a logical set of devices, policies, and requirements, which can be managed dynamically. The members of the virtual server group are functionally identical and serve as resources that can be added or removed as needed.
To use the Virtual Server Groups summary window, follow these steps.
Step 1 To locate the Virtual Server Group summary window, click the Virtual Server Groups folder in the left menu.
If one or more virtual server groups are already created, they appear in the main window (to the right of the navigation tree). Click the + sign next to any virtual server group to view the virtual servers that belong to that group as shown in Figure 12-1.

You can start the diagnostic process on any virtual server from the VFrame UI, as long as the virtual server's state is "ready," "disable," or "failed and unassigned." Refer to Table 5-4 on page 5-7 for state descriptions.
When Diagnostic Mode is enabled note the following information:
–VFrame performs a persistent login on a virtual server
–The Fibre Channel gateway in the server switch performs the login to target/LUNs for the selected virtual server. The login session remains intact until you choose Exiting Diagnostic Mode.
–You can change the Fibre Channel zoning, modify the SRP configuration, and verify the result with ITL current states. You may want to configure your storage device at this time, as the WWPN of the virtual server should appear to the storage device.
–The virtual server needs to exit the Diagnostic Mode before being assigned to any other physical server.
l. Remove a virtual server from Diagnostic Mode (and persistently logging into storage) by clicking the appropriate boxes and choosing Exit Diagnostic Mode for Selected Virtual Server(s).
The following occurs when a virtual server is removed from Diagnostic Mode:
–The virtual server is logged out of the target and the LUNs.
–The diagnostic result determines the new state of the virtual server.
–If the virtual server can access all configured targets and LUNs, the diagnostic result is success and the virtual server is set to "ready."
–If the virtual server cannot access all configured targets and LUNs, the diagnostic result fails and the virtual server is set to "failed."
m. To enable policies on a virtual server, check the check box next to the virtual server and choose Enable Policy for Selected Virtual Server(s) from the Select an Action drop-down menu.

Viewing and Managing Virtual Server Group Storage
Shared storage is used among all the virtual servers that have been created within a virtual server group. This functionality supports your shared storage, or database shared files, and requires your application to support clustered fileshare.
To utilize your shared storage, create virtual server groups with which to associate the storage resources. The shared storage is then used by any virtual servers that are added to that group.
The virtual server group Storage tab has sub-tabs for performing the following tasks:
•Viewing and Managing Shared Storage
•Viewing and Managing Group Access to Fibre Channel Ports
Viewing and Managing Shared Storage
To view and manage shared storage, using the Virtual Server Group Shared Storage window (or virtual server group Storage Assignments tab), follow these steps:
Step 1 Click the + sign in the Virtual Server Groups menu located in the navigation tree.
Step 2 Click a user-defined virtual server group.
The Virtual Server tab appears for the virtual server group.
Step 3 Click the Storage tab.
The Storage Assignments tab appears by default as shown in Figure 12-12.
Figure 12-12 Virtual Server Group Shared Storage
Step 4 View the WWPN of a target and the logical ID of a LUN for any previously discovered shared storage in the virtual server group in the Name field.
Step 5 View the current status of shared storage in the State field. See Table 8-3 on page 8-4 for a description of possible states of targets and LUNs.
Step 6 View the assigned description of any shared storage for the virtual server group in the Description field.
Step 7 View the size of the LUN in the Size field.
Step 8 View the order that has been assigned to any shared storage in the Device ID field.
The Device ID field is used in both shared and dedicated storage to configure the order in which a disk will be used.
Device IDs have the following properties:
•Device IDs span dedicated and shared storage.
•Device IDs must be numbered 0 through n - 1, where n is the number of devices. For example, 3 disks would be numbered as 0, 1, and 2.
•The device that is numbered 0 is the boot device.
•Device IDs use target binding on the host to order targets.
•The Director uses SRP logical unit (LU) remapping (SRP LU ID) to achieve the desired order of LUs.
Step 9 View the Boot LUN field to determine whether the target/LUN pair is configured to accesses the LUN for booting.
This field is set to true for the target/LUN pair with Device ID 0 and for the alternate boot path to this LUN, if one is configured. All other target/LUN pairs show false in this field.
Step 10 From the Select an Action drop-down menu, choose Modify Storage Assignment to assign shared storage or change current storage assignments. Refer to the "Modifying Virtual Group Shared Storage" section.
Modifying Virtual Group Shared Storage
To use your shared storage, create virtual server groups with which to associate the storage resources. The shared storage is then used by any virtual servers that are added to that Group.
You do not need to use this window if you do not have the capabilities for shared storage.
To associate shared storage with the virtual server group, using the Modify Virtual Server Group Shared Storage window, follow these steps:

Step 3 Once the shared storage is discovered, you can configure the way the storage will be used.
Step 4 Check the Assigned check box to assign the storage LUN to this virtual server group.
The Assign check box is dimmed and cannot be checked if the storage LUN has already been assigned to another virtual server. This protection is enforced by default so long as the No button is selected in the Allow selection of storage assigned to another virtual server field. Use caution if you choose to override this protection.
Step 5 Enter the order in which the storage will be used into the Device ID field. The Device ID refers to the order that the storage will be used.
Device ID 0 indicates the boot device. Do not use the integer 0 for any shared storage.
Step 6 Click the radio button in the Alternative Boot field if the LUN is to be designated as an alternate boot LUN.
The LUN designated as an alternate boot LUN must have the same logical LUN ID as the primary boot LUN and must be accessed through a different target. VFrame enforces these rules by dimming the Alternate Boot field radio buttons for all target/LUN pairs except those that comply with the rule.
This mechanism provides an alternate path to the boot LUN in case the primary path is not available.
Step 7 Check Apply to save your changes.

Step 10 Click the Refresh button to update the information in this window.
Viewing and Editing Minimum Equipment Requirements
The Minimum Equipment Requirements are used to place parameters around the kind of physical server that will be allowed to join a virtual server group.
If a physical server is needed for service, VFrame Director checks the standards you set in the Minimum Equipment tab and determines if a particular server meets those requirements. If the server hardware does not fit the specified standards, the server will not be used for that virtual server group. You can be more strict or less strict in your specifications, depending on the needs of your applications.
When you enter your requirements for the virtual server group on the Minimum Equipment tab, keep in mind that some requirements are considered satisfied if a server is found to have greater than or equal to the specified standard, and some requirements must be equal to.
For example, if you set a requirement that the only type of CPU that can be used by the virtual server group is Intel, then any server being considered must have an Intel CPU to satisfy the requirement. However, if you set a CPU speed of 2000 MHz, then any server with a speed greater than or equal to 2000 MHz would satisfy the requirement.
Step 1 Click the + sign in the Virtual Server Groups menu item located in the navigation tree.
Step 2 Click a user-defined virtual server group in the expanded navigation tree.
A user-defined virtual server group is any virtual server group other than the unassigned virtual server group. The Virtual Server tab appears for the virtual server group.

Leave the entry empty if you do want to specify this field.
If you type an entry in this field, the virtual server group will require that any physical server be equal to this entry for it to be allowed into the group.
Step 5 Enter the minimum number of CPUs that a server must have in order to be accepted by the virtual server group in the # CPUs field.
The virtual server group will require that any physical server be greater than or equal to this entry for it to be allowed into the group. Set to 0 if you want to ignore this field. Refer to the Table 12-1.
Step 6 Enter the minimum CPU speed in MHz that this virtual server group will accept in the CPU Speed field. For example, 1800 MHz.
CPUs with speeds equal to or over this amount will also be allowed into the group. Set to 0 if you want to ignore this field. Refer to the Table 12-1 to understand how this field will be read.
Step 7 From the Minimum Number of HCAs drop-down menu, choose the minimum number of HCAs that this virtual server group must contain.
Any servers allowed into the virtual server group will be required have equal to the number of HCAs that you specify. You can set this field to 1 or 2, 1 is the default value.
Step 8 Enter the minimum amount of memory in megabytes that this virtual server group will accept in the Memory field. For example, 1 MB.
Servers with memory equal to or exceeding this amount will be allowed into the group. Set to 0 if you do not want to specify this field.
Step 9 Enter the type of chipset a server must have to join a virtual server group in the Chipset field.
Use this field if you have specific requirements in order for devices to be utilized. This field can be entered with free-form text and is case-insensitive.

Managing Policies
Policies provide the ability to monitor and take action based on triggers. For example, a trigger could be when the average processor usage across a virtual server group reaches 60 percent. The corresponding action could be to add another virtual server to the group. In addition, policies provide a type of management; for example, you could use a time of day policy to remove all virtual servers from service for maintenance.
Policies can be based on the following kinds of trigger:
•Ping action
•A time of day
•A single SNMP variable
•Multiple aggregate SNMP variables
•Logic SNMP variables
•XML messages
The following topics describe the tasks you can perform to manage policies:
•Viewing Policies Configured for a Virtual Server Group
•Adding a Policy
•Deleting a Policy
•Enabling or Disabling Policies
•Viewing and Editing a Policy
Viewing Policies Configured for a Virtual Server Group
To view policies configured for a virtual server group, or to initiate actions on those policies, using the virtual server groups Policies tab, follow these steps:
Step 1 Click the + sign in the Virtual Server Groups menu item located in the navigation tree.
Step 2 Click a user-defined group in the expanded navigation tree.
A user-defined virtual server group is any virtual server group other than the unassigned virtual server group. The Virtual Server tab appears for the virtual server group.
Step 3 Click the Policies tab.
Figure 12-25 User-Defined Virtual Server Group Policies Tab
Step 4 Use the Select an Action drop-down menu to perform the following tasks:
a. Choose Add New Policy to create a new policy for the virtual server group. See the "Adding a Policy" section.
b. Choose an existing policy and choose Delete Selected Policy to remove a configured policy.
c. Check or uncheck the Enabled check box and choose Apply Changes to Enabled State to enable or disable an existing policy for the virtual server group.
Step 5 View the current policies in the Description field.
The "Monitor servers using ping" policy is created by default. This policy pings the management interface of the virtual servers to check the state. If the ping fails for a virtual server, the state is reported and can be viewed in the UI (refer to the "Viewing and Managing Virtual Servers in a Group" section). This policy can be edited or disabled as desired. However, if this policy is disabled or deleted, the virtual server state will be checked only when an action is performed on that device and VFrame might not be aware if the virtual server is actually in a good state.
Click Description to sort the list of policies. Click the policy description to edit the policy. The window that appears depends on the type of policy:
•Viewing and Editing a Ping-Based Policy
•Viewing and Editing a Time of Day Policy
•Viewing and Editing an SNMP Policy—Single Variable
•Viewing and Editing an SNMP Policy—Multiple Aggregate Variables
•Viewing and Editing an SNMP Policy—Multiple Logic Variables
•Viewing and Editing an XML Policy
Step 6 View the state of the policy in the Enabled field to determine if the policy is currently active.
Note Policies enabled or disabled through the SOAP programmatic interfaces do not affect the status of the Enabled check box in this window. SOAP interfaces enable or disable at the virtual server level and do not affect the information displayed in the virtual server group Policies tab, even if the SOAP interfaces enable/disable all virtual servers in the group. The Enabled check box in the virtual server details window reflects changes caused by the SOAP interfaces. See the "Viewing and Editing General Properties of a Virtual Server" section and Appendix E, "Accessing VFrame Web Services Through SOAP Interfaces," for details.
Step 7 View the Expired field to determine whether the policy has expired.
A policy expires after its configured end date, See "Adding a Policy for Time of Day Triggers" section for information about setting the end date for a policy.
Adding a Policy
Add policies to a group of virtual servers to create sets of triggers and actions that are appropriate for that group.
Use the Add Policy Step 1 of 2 window to begin adding a new policy. Step 2 depends on the type of policy you are creating. The step 1 window will guides you to the appropriate screen.
To use the Add Policy Step 1 of 2 window, follow these steps:
Step 1 Click the + sign in the Virtual Server Groups located in the navigation tree.
Step 2 Click a user-defined virtual server group in the navigation-tree. The Virtual Servers tab appears for the virtual server group.

Step 4 From the Select an Action drop-down menu, choose Add New Policy. The Add Policy Step 1 of 2 window appears as shown in Figure 12-26.
Figure 12-26 Virtual Server Group Policy Triggers
Step 5 from the Trigger Type drop-down menu, choose the type of trigger you want to apply to your policy.
a. Choose Ping to set a trigger that will be activated if the ping of a chosen interface fails. See the "Adding a Policy for Ping Triggers" section.
b. Choose Time of Day to select an action to be performed on a virtual server group at a specified time. For example, you can configure a policy that causes a server to be removed from a virtual server group at a specified time. See the "Adding a Policy for Time of Day Triggers" section.
c. Choose SNMP to set triggers for virtual server groups based on specified thresholds, as well as selecting the desired action. For example, you may determine that the trigger will be CPU utilization rising above 60 percent. In addition, you would select an action to be taken if this trigger is activated. For example, you may decide to have a server dynamically added to the virtual server group to cover the needed utilization.
When you select SNMP, the window expands to offer the choice between single SNMP variable and multiple SNMP variables as shown in Figure 12-27.

Adding a Policy for a Single SNMP Variable Trigger
Use the Add Policy Step 2 of 2 window to create a policy for a single SNMP variable trigger.
To create a policy based on multiple SNMP variables, reference one of these topics:
•Viewing and Editing an SNMP Policy—Multiple Aggregate Variables
•Viewing and Editing an SNMP Policy—Multiple Logic Variables
To create a policy triggered by the condition of one SNMP variable in each virtual server, follow these steps:
Step 1 Locate the Add Policy Step 1 of 2 window, and choose SNMP from the Trigger Type drop-down menu. In the Multiple Variables field, click the No radio button, and then click Next. See the "Adding a Policy" section.
The Add Policy Step 2 of 2 window appears for the SNMP Variable policy as shown in Figure 12-31.
Figure 12-31 Add Policy Based on a Single Variable SNMP Trigger
Step 2 From the SNMP Interface pull-down menu, choose the SNMP interface on which to set the policy. The interface is the management interface included in the virtual server configuration.
Step 3 Enter the SNMP interface port number in the Port field.
Step 4 Enter the community string in the SNMP Community field, such as secret.
Step 5 Use the SNMP OID field to perform these tasks:
•Click the Pre-defined OID radio button to select an SNMP Object Identifier that was previously created.
•Click the Custom OID radio button to enter a SNMP Object Identifier that does not yet exist. Enter the text or numerical SNMP Object Identifier in the SNMP OID field. For example, 1.3.6.1.4.1.2021.11.9.0
Step 6 Enter the type of SNMP value that you want to trigger a policy in the Value Type field. VFrame Director determines whether or not the set conditions or thresholds have been surpassed by looking for the SNMP variable that you set, such as:
•Integer—Notifies VFrame Director that it will be looking for a number value.
•Unsigned Integer—Notifies VFrame Director to look for an unsigned integer (a value that is not specifically defined as either positive or negative).
•String—Notifies VFrame Director to look for a particular text string.
•Decimal—Notifies VFrame Director to expect a decimal number.
•Timeticks—Notifies VFrame Director to determine whether or not a threshold has been exceeded by a certain amount of time passing.
Step 7 Use the Condition drop-down menu to set a condition for the policy.
The condition that you set determines how you want to measure the conditions that would activate a trigger within the virtual server group.
a. Choose Average Value for all Virtual Servers. This policy checks for the average value of all virtual servers in the virtual server group to determine if the policy has been violated.
b. Choose Value for all Virtual Servers. This option sets the policy to consider the conditions of all virtual servers (and not any individual) in the virtual server group to determine if the policy has been violated. Every server must satisfy the criteria independently to determine if the policy has been violated. For example, if all servers are overloaded, this policy could add a new server because load balancing will not help if every virtual server is fully loaded.
c. Choose Value for any Virtual Server. This option sets the policy to consider the conditions of any individual virtual servers in the virtual server group to determine if the policy has been violated.
Step 8 Use the Operator drop-down menu to further define the way the SNMP value policy should be read:
a. Choose greater than to have the trigger activated if a value associated with the SNMP OID is greater than the value you specify in the Threshold Value field.
b. Choose greater than or equals to have the trigger activated if a value associated with the SNMP OID is equal to or exceeds the value you specify in the Threshold Value field.
c. Choose less than to have the trigger activated if a value associated with the SNMP OID is below the value you specify in the Threshold Value field.
d. Choose less than or equals to have the trigger activated if a value associated with the SNMP OID is equal to or falls below the value you specify in the Threshold Value.
e. Choose equals to have the trigger activated if a value equals the value or text string you specify in the Threshold Value field.
f. Choose contains to have a trigger activated if a string value associated with the SNMP OID contains the string specified in the Threshold Value field.
Step 9 Enter a threshold value, such as a maximum percentage of utilization in the Threshold Value field.
The threshold value sets the area above or below which an action should be taken on the virtual server group. For example, if you want an action to be taken if the CPU performance of a virtual server falls below 60 percent, enter 60 in the Threshold Value field.
Step 10 Enter a value in seconds in the For a Duration of field.
This policies field allows you to set a particular amount of time (seconds) for which a threshold must be exceeded before a trigger is set. If you want a trigger to be set (and action taken) immediately after a threshold is exceeded, enter 0 in this field.
Step 11 Choose the action that you want to be taken in the event of a policy trigger from the Action field.
The list of possible actions might be limited by the other options you select.
a. Choose Send Email Notification. If you use this option, you must configure Email Notification in the Health menu. See the "Configuring Email Notification" section on page 8-7.
Enter an identifiable description of the policy in the Policy Description field.
b. Choose Add Physical Server(s) to Virtual Server Group. Selecting this option means that physical servers will be moved from the unassigned virtual server group and added to the virtual server group if the policy triggers. This response assumes that physical servers are available and meet the necessary requirements of the virtual server group. Requirements are set in virtual server group Minimum Equipment tab. See the "Viewing and Editing Minimum Equipment Requirements" section.
–Enter a value in the Number of Servers to Add/Remove field. This number indicates the number of physical servers that should be taken from the unassigned virtual server group for use when the policy triggers.
–Enter an identifiable description of the policy in the Policy Description field.
c. Choose Remove Physical Server(s) from the Virtual Server Group. Selecting this option means that physical servers will be moved from the virtual server group and placed in the unassigned virtual server group if the policy triggers.
–Enter a value in the Number of Servers to Add/Remove field. This number indicates the number of physical servers that should be taken from the virtual server group and moved to the unassigned virtual server group when the policy triggers.
–Enter an identifiable description of the policy in the Policy Description field.
d. Choose Set Virtual Server state. If the policy condition is met, the virtual server is placed in the Failed state. If the policy condition is not met, the virtual server is placed in the Active state.
Step 12 Enter a description of the policy in the Policy Description field.
Step 13 Click the Back button to return to the Step 1 window. See the "Adding a Policy" section.
Step 14 Click the Finish button to add the new policy.

Viewing and Editing General Properties of a Virtual Server
A virtual server allows a server to be disassociated from a server's physical state. Virtual servers belong to virtual server groups, and have attributes assigned to them, but they are dynamic in that they do not belong to a specific physical server.
Because VFrame Director enables an application to migrate from one physical server to another, virtual servers are used to keep track of the information that is required to make that application run on a given server, when needed.
You can view or edit general properties of a virtual server such as its name, state, and assigned physical server from the Virtual Server Properties window. To access this window and view or change the virtual server's general properties, follow these steps:
Step 1 Click the + sign in the Virtual Server Groups menu item located in the navigation-tree.
Step 2 Click a user-defined virtual server group name in the expanded navigation tree.
The Virtual Servers tab (or Virtual Servers Summary window) appears for the virtual server group. See the "Viewing and Managing Virtual Servers in a Group" section for details of the Virtual Servers Summary window.
Step 3 Click the name of the virtual server whose properties you want to view or edit.
The Virtual Server Properties window appears for the selected virtual server as shown in Figure 12-45.
Figure 12-45 Virtual Servers Properties
Step 4 View the name of the virtual server you are currently viewing in the Virtual Server drop-down menu.
You can also use this drop-down menu to view the general properties of another virtual server in the group or to return to the Virtual Servers Summary window. (See the "Viewing and Managing Virtual Servers in a Group" section.)
Step 5 View or edit the name of the virtual server you are currently viewing in the Hostname field.
Step 6 Enable or disable policies for the virtual server by checking or unchecking the Policy Enabled check box. Click Apply to make the change.
Note You can also enable or disable policies for a virtual server programmatically using SOAP interfaces, as described in Appendix E, "Accessing VFrame Web Services Through SOAP Interfaces."
Step 7 View the IP address of the management network for the virtual server in the Mgmt Address field.
Step 8 View the current state of the virtual server in the State field. Refer to Table 5-4 on page 5-7 for descriptions of possible states.
Step 9 View the name of the physical server assigned to the virtual server in the Current Physical Server field.
Step 10 Change the physical server assigned to the virtual server in the New Physical Server drop-down menu. Also use this field to unassign a physical server.
Step 11 Add customization properties for the virtual server in the Customization Parameters field. Refer to the "Understanding Image Manipulation and Customization" section on page 13-1 for more information.
Step 12 Click the Apply button to save any changes to the virtual server properties.
Step 13 Click the Refresh button to update the information in the window.
Step 14 Click the Diagnostic Report button (visible only in diagnostic mode) to view the storage access for a virtual server. Refer to the "Verifying Storage Access Through Diagnostic Reports" section.
Step 15 Click the Disable Virtual Server button (not visible in diagnostic mode) to prevent the virtual server from being used by VFrame Director.
Step 16 Click the Initialize Storage button (not visible in diagnostic mode) to prepare the storage for use.
This task can be done either during model virtual server creation (see the "Step 5 of 8—Initializing Storage for a Model Virtual Server" section on page 11-21) or later from this window. Alternatively, you can initialize storage for multiple virtual servers in one operation from the Summary of Master Images window, as described in the "Initializing Storage for Multiple Virtual Servers" section on page 13-11. This task should be done before installing the operating system and applications on the dedicated storage.
Although optional, storage initialization is highly recommended. The process may take over a minute per gigabyte of dedicated storage, depending on the speed of your storage devices. However, initializing the dedicated storage significantly reduces the amount of time that it takes to create a new image and deploy that image.
Verifying Storage Access Through Diagnostic Reports
To verify access to target/LUN pairs from a selected virtual server, run a diagnostic report.
To verify access, follow these steps:
Step 1 Click the + sign in the Virtual Server Groups menu item located in the navigation-tree.
Step 2 Click a user-defined virtual server group name in the expanded navigation tree.
The Virtual Servers Summary window appears under the Virtual Servers tab.
Step 3 Check the check box next to the name of the virtual server you want to diagnose.
Step 4 From the Select an Action drop-down menu, choose Enable Diagnostic Mode for Selected Virtual Server(s).
Only one virtual server can be selected for Diagnostic Mode at one time.
You can start the diagnostic process on any virtual server from VFrame GUI, as long as the virtual server's state is ready, disable, or failed and unassigned. Refer to Table 5-4 on page 5-7 for state descriptions.
The state of the virtual server changes to Entering Diagnostic.
Step 5 Click the virtual server name in the Virtual Servers Summary window.
The appears of the selected virtual server.
Step 6 Click the Diagnostic Report button to view the storage access for a virtual server. The Diagnostic Report appears as shown in Figure 12-46.
Diagnostic Mode verifies the virtual server setup by checking target/LUN access.
When Diagnostic Mode is enabled, the following occurs:
•VFrame performs a persistent login on a virtual server.
•The Fibre Channel gateway in the server switch performs the login to target/LUNs for the selected virtual server. The login session remains intact until you select Exiting Diagnostic Mode.
•You can change the Fibre Channel zoning, modify the SRP configuration, and verify the result with ITL current states. You may want to configure your storage device at this time because the WWPN of the virtual server should appear to the storage device.
The virtual server must exit the Diagnostic Mode before being assigned to any other physical server.
Figure 12-46 Diagnostic Report for Virtual Server
Step 7 View the World Wide Names (WWNs) information for the selected virtual server:
a. View the assigned World Wide Node Name (WWNN) for the virtual server in the WWNN field.
b. View the Host Channel Adapter that is associated with the displayed WWNN in the HCA field.
c. View the assigned World Wide Port Name (WWPN) for the virtual server in the WWPN field.
d. View the alias assigned to the group of Fibre Channel ports in the Port Pool field. The port pool is the pool to which the WWPN and gateway port are associated. The WWPN will be assigned only to a port in that pool.
e. View the alias of the server switch in the Server Switch field. This switch alias identifies the Fibre Channel gateway port to which the WWPN has been assigned. The Fibre Channel port is one of the ports in the port pool, specified in the Port Pool field.
f. View the slot number of the server switch to which the virtual server is connected to storage in the Slot field. This slot number identifies the Fibre Channel gateway port to which the WWPN has been assigned. The Fibre Channel port is one of the ports in the port pool, specified in the Port Pool field.
g. View the port number of the Fibre Channel gateway to which the virtual server is connected to storage in the Port field. The port identifies the Fibre Channel gateway port to which the WWPN has been assigned. The Fibre Channel port is one of the ports in the port pool, specified in the Port Pool field.
h. View the Fibre Channel address for the virtual server in the FC Address field. The Fibre Channel address is the 24-bit Fibre Channel address currently assigned to the specified Fibre Channel gateway port of the virtual server. A value of 00:00:00 indicates that the link is not currently up.
Using this field to troubleshoot storage access problems.
Check that an Fibre Channel port to which the WWPN is bound has a nonzero Fibre Channel address. If the Fibre Channel address is 00:00:00, perform the following steps:
–Check that the gateway port is enabled.
–Check that the cable is inserted properly.
–Check that the Fibre Channel gateway port to which the WWPN is bound is on the same Fibre Channel fabric as the Target port of the storage device. Correct the cabling if necessary.
–Check the Fibre Channel zoning configuration on the Fibre Channel fabric to which the gateway port is connected. The virtual server WWPN and target WWPN must be in a common zone. Correct any zoning errors.
–Regenerate the diagnostic report after you have corrected any problems.
Step 8 View the assigned storage configuration for the virtual server in the Storage Access fields:
a. View the target port of the storage device to which the virtual server has been assigned in the Name field.
View the LUN of the storage device to which the virtual server has been assigned in the Name field.
b. View the actual state of the virtual server storage access in the Virtual Server WWPNs with Access field. This field is the most significant field in the diagnostic report, as it shows the WWPNs through which the virtual server can see the storage. There should be at least one WWPN displayed through which the virtual server can see each target and LU.
The virtual server attempts to log into the storage fabric when Diagnostic Mode is enabled. If the virtual server successfully connects to storage, the WWPNs used to connect to the storage are displayed. This feature allows you to verify the accuracy of the storage configuration.
You may want to configure the WWPN in your storage device while the virtual server is in Diagnostic Mode. When a server is logged into the fabric, the WWPN is discovered automatically by storage, which prevents you from having to enter the WWPN string manually.
Use this field to troubleshoot storage access problems.
If there is a WWPN with which the virtual server should see a target, but is not in the list of WWPNs with access, do the following:
–Check the virtual server WWPNs table to verify that the WWPN is bound to an Fibre Channel gateway port.
–If the WWPN is not bound to a gateway port, there may not be enough Fibre Channel ports in the port pool with which to bind.
–Add additional Fibre Channel ports to the port pool with which the WWPN is associated.
–Exit Diagnostic Mode
–Reenable Diagnostic Mode and regenerate the report.
Step 9 Click the Print Report button to print a hard copy of the storage configuration for the virtual server.
Step 10 Click the Re-generate Report button to update the information after any storage configuration changes have been made.

Step 3 View the WWNNs sections.
A WWNN is assigned to allow Fibre Channel devices to communicate with the HCA (and the virtual server) as if communicating with another Fibre Channel device. The unique WWNNs also allow normal Fibre Channel zoning and access control methods to function as usual.
a. View the number of the virtual Host Channel Adapters (HCA) assigned to the virtual server in the Virtual Adapter field. The first adapter is always 0 and a second HCA is always 1.
b. View the WWNN of the virtual adapter in the WWNN field.
Step 4 View the WWPNs sections.
VFrame generates virtual values for the Fibre Channel gateway (as a node) and WWPNs for individual ports. The number of WWPNs assigned depends on the number of ports you chose to be in the Fibre Channel port pool.
a. View the WWNN generated for the virtual server in the WWNNs field. This value is necessary for some types of Fibre Channel zoning.
b. View the WWPN of the virtual port of the Fibre Channel gateway generated for the virtual server in the WWPNs field. Copy this value for Fibre Channel zoning.

See the "Modifying Virtual Server Dedicated Storage" section for details.
Modifying Virtual Server Dedicated Storage
The Virtual Server Dedicated Storage tab allows you to modify the dedicated storage for a virtual server. To modify dedicated storage, follow these steps:
Step 1 Access the Modify Dedicated Virtual Storage window from the Virtual Server Storage window as described in "Viewing Dedicated Storage" section.
The Modify Dedicated Virtual Server Storage window appears as shown in Figure 12-51.
Figure 12-51 Modify Virtual Server Dedicated Storage
Step 2 In the Allow selection of storage assigned to another virtual server field, the No button is selected by default. This default selection prevents you from allocating the same dedicated storage to this virtual server as has already been assigned to another virtual server.
Use caution if you chose to override this protection.
Step 3 View the WWPN of any previously discovered dedicated storage in the virtual server group in the Name field. Refer to the "Viewing or Modifying Target Properties" section on page 9-41 to edit a target.
Step 4 View the logical ID of the LUN in the Name field. Refer to the "Viewing and Editing Logical Unit Properties" section on page 9-45 to edit a LUN.
Step 5 View the current status of storage in the State field.
Step 6 View or edit the description previously assigned to the LUN in the Description field. To edit the description, See the "Viewing or Modifying Target Properties" section on page 9-41.
Step 7 View the size of the LUN in the Size field.
Step 8 View any previously assigned storage in the Assigned field. Select the dedicated storage to which you want to assign the virtual server by clicking the Assigned check box.
If the Assigned check box is dimmed, then that storage is already assigned to another virtual server. This protection is enforced by default so long as the No button is selected in the Allow selection of storage assigned to another virtual server field. Use caution if you choose to override this protection.
The Device ID check box appears next to the chosen storage after checking the check box in the Assigned field.
Step 9 Enter the order in which the storage will be used into the Device ID field.
The Device ID refers to the order that the storage will be used.
Device ID 0 indicates the boot device. Do not use the integer 0 for any shared storage.
Step 10 Click the radio button in the Alternative Boot field if the LUN is to be designated as an alternate boot LUN.
The LUN designated as an alternate boot LUN must have the same logical LUN ID as the primary boot LUN and must be accessed through a different target. VFrame enforces these rules by dimming the Alternate Boot field radio buttons for all target/LUN pairs except those that comply with the rule.
This mechanism provides an alternate path to the boot LUN in case the primary path is not available.
Step 11 Click Apply to save your changes.
