Understanding Discovery Jobs

Discovery brings the physical resources of the data center into the VFrame database. Physical resources are network devices, such as Ethernet switches and service modules; storage devices, such as NAS filers, Fibre Channel switch switches, Storage Managers, and storage arrays; and servers, such as application servers and LOM managers. When you run discovery, use the Discovery Job dialog box to specify the scope of discovery as well as the type of elements you want discovered. The result is a discovery job, which you can rerun whenever you want.

You can discover the following elements:

Network

•Network Devices—Cisco Discovery Protocol (CDP) is used for network discovery. Enter the DNS name or IP address of a CDP seed device (any device on which the CDP protocol is enabled and an SNMPv2 read community string or SNMPv3 credential is configured). VFrame discovers all neighboring switches (in the specified distance) starting with the ones directly connected to the seed device and obtains information about those devices.

Storage

•NAS filers—Enter the IP address or DNS name of the NAS filer; VFrame discovers the NAS filer, its volumes, Quota Trees (QTrees), and Common Internet File System (CIFS) shares.

•Fibre Channel Switches—You can use one or two physical SAN fabrics. Enter the IP address or DNS name of the seed Fibre Channel switch for each physical fabric. For physical fabrics comprised of Cisco MDS Fibre Channel switches, VFrame discovers all neighboring MDS switches in each fabric that have member ports in the same active VSANs as the seed switch. For physical fabrics comprised of Brocade Fibre Channel switches, VFrame discovers all neighboring Brocade switches. VFrame also discovers the connected device World Wide Names (WWN) for each discovered Fibre Channel switch. For details about Fibre Channel switches, see Fibre Channel Switches, page 3-4).

•Storage Managers—When you select a Storage Manager and run discovery, VFrame discovers the storage arrays configured to be discovered through the Storage Manager and the related port and logical unit information.

Before you run Storage Manager discovery, you must use a Storage Manager Template with defined macros. With macros, you control the logical units and ports that should be visible to a particular server. You can use these macros for inventory of storage array ports and logical units and for logical unit masking and unmasking. For details about storage manager templates, see Storage Manager Templates, page 11-58.

For details about storage managers, see Storage Managers, page 3-4.

Servers

Application servers are discovered using the inventory operating system (OS). Running the inventory OS is a process through which VFrame obtains hardware details about the server. When a server is PXE booted, VFrame responds to the PXE boot request by providing an IP address and the inventory OS. After the inventory OS runs on the server, VFrame obtains the server hardware inventory, such as its CPU, speed, memory, and system partitions.

•DHCP—You must configure a Dynamic Host Configuration Protocol (DHCP) range in VFrame to provide a pool of IP addresses VFrame can use during server discovery or golden image creation from model servers. For the procedure on how to configure the DHCP range, see Adding or Modifying DHCP IP Address Ranges, page 5-4.

For VFrame to discover application or model servers, you must PXE boot the servers. During PXE boot, the server sends a DHCP request. VFrame responds to the DHCP request only on its server communication interface, so make sure that the server is set up correctly, otherwise the server will not be discovered (see Setting Up Servers, page 3-15).

For more information about DHCP, see Understanding How VFrame Uses DHCP, page 5-1.

•LOM Managers—You must select a lights-out management (LOM) manager and run discovery to obtain the IP addresses of the LOM interfaces.

VFrame uses LOM managers and LOM configuration macros to control the power of the servers.VFrame runs the macros on the specified LOM manager to retrieve a list of LOM interfaces associated with the physical servers, to power on and power off the servers, and to obtain the power status of the servers.

For details about LOM manager templates, see LOM Manager Templates, page 11-63.

Virtual Machine Managers

Enter the IP address or DNS name of the virtual machine manager; VFrame discovers the virtual machine manager, its unique identifier assigned by VFrame, its version and build number, and its top-level inventory of virtual machine containers, such as virtual servers.

Understanding How Discovery, Rediscovery, and Reinventory Differ

When you create a discovery job, you can specify that the job run multiple times on a regular schedule. For example, you could have the job run every week.

The benefit of rerunning discovery jobs is that it allows VFrame to notice changes in the network. For example, if you run a network discovery job using 2 as the CDP distance, and you add a new switch to the network within that distance to the CDP seed device defined in the discovery job, the rediscovery of the CDP seed will notice the new switch and add it to the VFrame database. You can then click it in the device selector on the Resources tab and manage it.

Additionally, discovery jobs reevaluate the resources that were previously discovered. It is this activity of reexamining known devices that is called rediscovery. During a discovery job, if VFrame evaluates an already known device, it runs the inventory process on the device. (Inventory is initially run when you first manage a device, and subsequent inventories are considered reinventories.)

During rediscovery and reinventory, VFrame can identify many configuration changes, such as the addition of security contexts to a managed FWSM or new VLANs on managed switches. These changes are reflected in the database, and you can manage the new resources.

After rediscovery and reinventory, the database will reflect the current state of the resource configuration. However, if you made configuration changes that VFrame cannot accommodate (such as deleting a managed VLAN from a switch), the process will raise fault alarms identifying the problematic changes.

Device Rediscovery Tips

The following tips might help you understand what happens during rediscovery, and how to avoid some pitfalls:

•Network Rediscovery—When the Ethernet switches and service modules are rediscovered, the device inventory is updated and the updated list is displayed in the device selector on the Resources tab. You can manage any new VLANs or FWSM security contexts. When a replaced switch is rediscovered, the device inventory is not updated. Instead, a system message will appear with instructions about device replacement.

•SAN Fabric Rediscovery—When the SAN fabric is rediscovered, the device inventory is updated and the updated list is displayed in the device selector on the Resources tab.

We recommend that you do not move the seed switch from one fabric to the other. If you need to move it, first select another switch to serve as the seed switch for that fabric, and then move it, otherwise discovery will fail.

VFrame supports two fabrics, for example, Fabric 1 and Fabric 2. If you need to discard the existing physical switch topology and use a new topology as Fabric 1 or Fabric 2, we recommend that you perform the following tasks:

–Delete the existing Fabric 1 and Fabric 2 from the Resources tab.

–Specify a new seed device and reschedule discovery.

We highly recommend that you follow these steps. VFrame does not enforce it to accommodate extreme hardware failures. For example, if all switches in Fabric 2 failed, and you had to replace them with new switches and cable them exactly the same way.

•LOM Manager Rediscovery—When the LOM managers are rediscovered, any changes in the server inventory are reflected in the LOM inventory database and displayed in the LOM manager details table on the Resources tab. If you added servers to the inventory, discover the new servers using the procedure described in Discovering Application Servers for Unassociated LOM Interfaces.

---

Note You can use the LOM inventory macro or the LOM Inventory dialog box to obtain LOM interface information. Both methods are equally valid and are intended to complement each other. The LOM inventory macro can be used when there are a large number of LOM interfaces to inventory; the LOM Inventory dialog box, which allows you to work with one LOM interface at a time, can be used for working with a smaller number of LOM interfaces, or for making incremental changes to a large inventory. For more information about using the LOM Inventory dialog box, see Working with the LOM Inventory.

Discovering Devices

This section describes how to discover devices, and includes the following topics:

•Discovering Ethernet Switches and Service Modules

•Discovering Storage Devices

•Discovering Servers

•Discovering Virtual Machine Managers

•Viewing the Discovery Status

•Rescheduling or Unscheduling Discovery Jobs

Discovering Ethernet Switches and Service Modules

You can discover network devices such as an Ethernet switch and its service modules.

Before You Begin

•Set up the Ethernet switch and service modules (see Setting Up Ethernet Switches, page 3-7 and Setting Up Network Services, page 3-9).

•Configure Ethernet switch and network services credentials in VFrame (see Configuring Network Credentials, page 4-6 and Configuring Network Services Credentials, page 4-7).

•Make sure that the seed device is connected to the network and can be reached (pinged) from the VFrame Data Center Director.

Procedure

---

Step 1 Choose Tools > Discovery to open the Discovery dialog box (see Discovery Dialog Box).

Step 2 Click New to open the Discovery Job dialog box. The Network tab is selected by default (see Network Tab).

Step 3 (Optional) To change the system-assigned job name, select the name and enter a new one.

Step 4 Perform one of the following tasks:

•To use the devices that you have already managed as CDP seeds, check the Rediscover currently managed devices check box.

•To use a new device as the CDP seed, or to control which devices are used, enter the DNS name or the IP address of a device that is running CDP in the Seeds field. A seed device is used as the root device for network discovery.

---

Note You can also enter multiple comma-separated seed IP addresses to be discovered at the same time.

---

Step 5 From the Distance drop-down list, select the number of CDP hops to use in the discovery. This number defines the scope of the discovery. For example, if you choose 1, then any device running CDP that is connected to your specified seeds is also discovered and added to VFrame. The default is 0, which means that only the devices you specify are discovered.

Step 6 In the Type of Discovery group, click one of the following:

•Run Now—To start the discovery job immediately when you click OK.

•Schedule—To specify a schedule for the job to run it in the future. Choose the date and time when you want the job to run.

If you schedule the discovery job, you can also check the Enable Repeat check box to schedule the job to be rerun until you cancel the job. Choose the frequency time period (such as hour or day), and enter the number of time periods for the recurrence schedule. For example, choosing 2 Weeks causes the discovery job to be rerun every 2 weeks until canceled.

Step 7 Click OK.

VFrame creates a discovery job and adds it to the jobs list in the Discovery dialog box. When the job starts, you can view its progress in the upper pane. The messages generated during the job progress appear in the Job Logs pane (the lower pane).

If discovery is successful, the discovered Ethernet switches, line cards, supervisor engine, and service modules in the switch are displayed in the device selector on the Resources tab under Network Devices.

If a device is unsupported, it appears under Unsupported Devices in the device selector on the Resources tab.

---

Next Step

After you discover the Ethernet switch and service modules, you can manage them (see Managing and Unmanaging Ethernet Switches, page 7-8 and Managing and Unmanaging Service Modules, page 7-12).

Discovering Storage Devices

This section describes how to discover storage devices, and includes the following topics:

•Discovering SAN Fabric Devices and Their Components

•Discovering NAS Filers and Their Components

•Discovering Storage Arrays and Their Components Through Storage Managers

Discovering SAN Fabric Devices and Their Components

You can discover the Fibre Channel switches in one or two physical SAN fabrics. For Cisco MDS-based physical fabrics the active VSANs in the seed switch determine which additional MDS switches will be discovered. For Brocade-based physical fabrics all switches will be discovered.

Before You Begin

•Set up the Fibre Channel switch (see Setting Up MDS Fibre Channel Switches, page 3-11 and Setting Up Brocade Fibre Channel Switches, page 3-12).

•Configure SAN Fabric credentials in VFrame (see Configuring SNMP Credentials for Fibre Channel Switches, page 4-8).

Procedure

---

Step 1 Choose Tools > Discovery to open the Discovery dialog box (see Discovery Dialog Box).

Step 2 Click New to open the Discovery Job dialog box.

Step 3 Click the SAN Fabric Devices tab (see SAN Fabric Devices Tab).

Step 4 (Optional) To change the system-assigned job name, select the name and enter a new one.

Step 5 Perform one of the following tasks:

•To use the seed devices that you used previously, click the Rediscover currently managed fabrics check box.

•To discover a single physical SAN fabric, enter the IP address or DNS name of the seed Fibre Channel switch in the Seed 1 field.

•To discover two physical SAN fabrics, enter the IP address or DSN name of the seed Fibre Channel switch for the first fabric in the Seed 1 field and the IP address or DSN name of the seed Fibre Channel switch for the second fabric in the Seed 2 field.

Step 6 In the Type of Discovery group, click one of the following:

•Run Now—To start the discovery job immediately when you click OK.

•Schedule—To specify a schedule for the job to run it in the future. Choose the date and time when you want the job to run.

If you schedule the discovery job, you can also check the Enable Repeat check box to schedule the job to be rerun until you cancel the job. Choose the frequency time period (such as hour or day), and enter the number of time periods for the recurrence schedule. For example, choosing 2 Weeks causes the discovery job to be rerun every 2 weeks until canceled.

Step 7 Click OK.

VFrame creates a discovery job and adds it to the jobs list in the Discovery dialog box. When the job starts, you can view its progress in the upper pane. The messages generated during the job progress appear in the Job Logs pane (the lower pane).

If discovery is successful, then the device tree in the Resources pane is updated with the discovered information for each physical fabric. For Cisco MDS-based physical fabrics, the VSANs present in the seed switch are displayed along with the seed switch and all neighboring switches reachable from the seed switch that have ports in those VSANs. For Brocade-based physical fabrics a single Administrative Domain (AD0) is displayed along with the seed switch and all neighboring switches reachable from the seed switch. The switch ports are also discovered, but they appear in the details table.

Step 5 Perform one of the following tasks:

•To use the IP address or DNS name of a previously discovered NAS filer, click the Rediscover currently managed NAS filers check box, then choose the NAS filer from the displayed list.

•In the IP Address/DNS Name field, enter the IP address or DNS name of the NAS filer.

Step 6 In the Type of Discovery group, click one of the following:

•Run Now—To start the discovery job immediately when you click OK.

•Schedule—To specify a schedule for the job to run it in the future. Choose the date and time when you want the job to run.

If you schedule the discovery job, you can also check the Enable Repeat check box to schedule the job to be rerun until you cancel the job. Choose the frequency time period (such as hour or day), and enter the number of time periods for the recurrence schedule. For example, choosing 2 Weeks causes the discovery job to be rerun every 2 weeks until canceled.

Step 7 Click OK.

VFrame creates a discovery job and adds it to the jobs list in the Discovery dialog box. When the job starts, you can view its progress in the upper pane. The messages generated during the job progress appear in the Job Logs pane (the lower pane).

If discovery is successful, the discovered NAS filer appears in the device selector on the Resources tab. The volumes, QTrees, and CIFS shares appear in the details table.

---

Next Step

After you discover the NAS filer, you can manage its volumes, QTrees and CIFS shares (see Managing and Unmanaging NAS Filer Components, page 7-14).

Discovering Servers

Table 6-1 is an overview of the steps you must take before you discover servers.

Table 6-1 Workflow for Server Discovery 

	Task
Step 1	Configure a DHCP IP address range and configure DHCP helpers if necessary. See the following topics: •Configuring DHCP in VFrame, page 5-4 •Configuring DHCP Relay Agents in Ethernet Switches, page 5-2
Step 2	Discover the LOM interfaces using any of the following methods: a. For server types supported by automatic LOM discovery, reboot the servers and wait for them to be discovered. See Automatic LOM Discovery. b. Discover the LOM interfaces and server inventory defined on the LOM managers. See Discovering LOM Interfaces and the Server Inventory Through LOM Managers. c. Manage the LOM inventory database by manually adding, editing, or deleting LOM interfaces using the LOM Inventory dialog box. See Working with the LOM Inventory. Note The LOM inventory macro can be used when there are a large number of LOM interfaces to inventory; the LOM Inventory dialog box, which allows you to work with one LOM interface at a time, can be used for working with a smaller number of LOM interfaces, or for making incremental changes to a large inventory. Both methods are equally valid and are intended to complement each other.
Step 3	Discover the servers for unassociated LOM interfaces. See Discovering Application Servers for Unassociated LOM Interfaces.

Automatic LOM Discovery

VFrame automatically discovers LOM interface information for some server types, but not all. The server types supported with automatic LOM discovery include the following:

•- HP iLO1, HP iLO2

•- IBM RSA2 Slimline, IBM BMC

•- Dell DRAC4 (DRAC5 is not supported)

With automatic LOM discovery, you do not need to manually provide LOM information to VFrame. The LOM information is discovered by VFrame Inventory OS and is reported to VFrame with the server inventory information. For all non-supported LOM types, you must manually provide the LOM information.

Each server type supported by automatic LOM discovery has a corresponding default internal LOM manager, where automatically discovered LOM interfaces are listed. The default internal LOM managers include the following:

•vfdclm_dell_drac4

•vfdclm_hp_ilo

•vfdclm_ibm_rsa2

Discovering LOM Interfaces and the Server Inventory Through LOM Managers

Before you can discover servers, you must discover the server inventory as it is defined on the LOM managers. The inventory includes information about the LOM interfaces on each server. VFrame discovers and manages the server by controlling it through the LOM interface.

Before You Begin

You must perform the following tasks before you discover LOM interfaces and the server inventory:

1. Set up the LOM manager. See the following topics:

–Creating LOM Inventory File for Application Servers, page 3-17

–Configuring VFrame as a LOM Manager, page 3-19

–Setting Up Independent LOM Managers, page 3-21

2. (Optional) Create LOM manager templates (see Creating and Modifying LOM Manager Templates, page 11-65). If the predefined templates fit your needs, you can use them instead of creating your own.

3. Define the LOM managers based on the LOM manager templates (see Defining LOM Managers, page 11-67).

4. Configure the LOM Manager and LOM interface credentials in VFrame (see Configuring Server Credentials, page 4-11).

Procedure

---

Step 1 Choose Tools > Discovery to open the Discovery dialog box (see Discovery Dialog Box).

Step 2 Click New to open the Discovery Job dialog box.

Step 3 Click the LOM Managers tab (see LOM Managers Tab).

Step 4 (Optional) To change the system-assigned job name, select the name and enter a new one.

Step 5 Choose the LOM managers whose inventory you want to discover.

Step 6 In the Type of Discovery group, click one of the following:

•Run Now—To start the discovery job immediately when you click OK.

•Schedule—To specify a schedule for the job to run it in the future. Choose the date and time when you want the job to run.

If you schedule the discovery job, you can also check the Enable Repeat check box to schedule the job to be rerun until you cancel the job. Choose the frequency time period (such as hour or day), and enter the number of time periods for the recurrence schedule. For example, choosing 2 Weeks causes the discovery job to be rerun every 2 weeks until canceled.

Step 7 Click OK.

VFrame creates a discovery job and adds it to the jobs list in the Discovery dialog box. When the job starts, you can view its progress in the upper pane. The messages generated during the job progress appear in the Job Logs pane (the lower pane).

If discovery is successful, the LOM interfaces and server inventory appear in the Details Table associated with each discovered LOM manager on the Resources tab (right-click the LOM manager in the device selector and click Show Details Table).

Working with the LOM Inventory

You can work the LOM inventory by manually adding, editing, or deleting LOM interfaces. The details table associated with each discovered LOM manager (on the Resources tab) displays the LOM inventory from the database.

---

Note In addition to using the LOM Inventory dialog box, you can use the LOM inventory macro in a LOM manager to inventory LOM interfaces. The LOM inventory macro can be used when there are a large number of LOM interfaces to inventory; the LOM Inventory dialog box, which allows you to work with one LOM interface at a time, should be used for working with a smaller number of LOM interfaces, or for making incremental changes to a large inventory.

---

Before you Begin

You must perform the following tasks before you manage the LOM inventory database:

1. Set up the LOM manager. See the following topics:

–Creating LOM Inventory File for Application Servers, page 3-17

–Configuring VFrame as a LOM Manager, page 3-19

–Setting Up Independent LOM Managers, page 3-21

2. (Optional) Create LOM manager templates (see Creating and Modifying LOM Manager Templates, page 11-65). If the predefined templates fit your needs, you can use them instead of creating your own.

3. Define the LOM managers based on the LOM manager templates (see Defining LOM Managers, page 11-67).

4. Configure the LOM Manager and LOM interface credentials in VFrame (see Configuring Server Credentials, page 4-11).

Procedure

---

Step 1 On the Resources tab (choose View > Resources), right-click the LOM manager in the device selector and click Show Details Table (see Viewing Details About a Selected Device Category or Element, page 7-24).

The details table lists the LOM interfaces in the LOM inventory.

Step 2 To add a new LOM interface to the LOM inventory:

a. Click New. The LOM Inventory dialog box appears (see LOM Inventory Dialog Box).

b. Enter the new LOM interface information.

c. Click OK. The new LOM interface is added to the database and appears in the details table.

Step 3 To edit an existing LOM interface in the LOM inventory:

a. In the details table, click the LOM interface to be edited.

b. Click Edit. The LOM Inventory dialog box appears (see LOM Inventory Dialog Box).

c. Change the existing LOM interface information.

d. Click OK. The LOM interface is updated in the database and the updated information appears in the details table.

Step 4 To delete an existing LOM interface in the LOM inventory:

a. In the details table, click the LOM interface to be deleted.

b. Click Delete. The LOM interface is removed from the database and the details table.

Discovering Application Servers for Unassociated LOM Interfaces

After you discover a LOM manager, the details table for the LOM manager lists all LOM interfaces contained in the LOM manager inventory. Any LOM interfaces that belong to undiscovered servers are listed in the Unassociated LOMs section of the table. These are the servers that you need to discover. After discovering a server, the server is added to the Servers folder in the device selector.

Before You Begin

•Set up the server (see Setting Up Application Servers, page 3-15).

•Discover the LOM managers (see Discovering LOM Interfaces and the Server Inventory Through LOM Managers).

•Create an appropriate DHCP IP address range for use during server discovery (see Adding or Modifying DHCP IP Address Ranges, page 5-4).

•Configure the LOM interface credentials in VFrame (see Configuring Server Credentials, page 4-11).

Procedure

---

Step 1 On the Resources tab (select View > Resources), right-click the LOM manager in the device selector and click Show Details Table.

The details table lists the LOM interfaces in the LOM inventory database.

Step 2 Click the Unassociated LOMs drop-down list. This list contains all of the servers that have not yet been discovered, based on their LOM interfaces.

Step 3 Choose one or more unassociated LOMs, right-click and click Power Reset. This action reboots the selected servers, resulting in server discovery. If the Power Reset option is not available in your VFrame version, please proceed to Step 4 and Step 5.

---

Note The Power Reset option will be dimmed if a DHCP range is not specified, because servers cannot be discovered without a valid DHCP IP address range.

---

Step 4 Choose one or more unassociated LOM interfaces, right-click and click Power Off. This action ensures that all servers are powered off.

---

Tip We recommend that you select a maximum of 10 interfaces at a time to keep resource utilization reasonable. You should also not select more servers than you have IP addresses in your DHCP IP address range table.

---

Step 5 Right-click the unassociated LOM interfaces you powered off and click Power On.

---

Note The Power On option will be dimmed if a DHCP range is not specified, because servers cannot be discovered without a valid DHCP IP address range.

---

Powering on the server boots it. If the server is configured correctly, it PXE boots. VFrame acts as the DHCP server and responds to the boot message with the following items:

•IP address from the appropriate DHCP IP address range.

•The inventory OS. After the inventory OS runs on the server, VFrame obtains the server hardware inventory, such as its CPU type, speed, memory, and system partitions.

It will take some time for the servers to finish booting and sending their physical attributes to VFrame. When the process finishes, the servers appear in the Servers folder in the device selector.

---

Tips

You can also discover the server by PXE booting it directly (outside of the VFrame interface). We recommend that you use a serial terminal connection to connect to the servers. Messages that are not displayed on the LOM web interface are displayed on the serial terminal.

Next Step

After you discover the servers, you can manage them (see Managing and Unmanaging Application Servers, page 7-20).

Step 1 Choose Tools > Discovery to open the Discovery dialog box (see Discovery Dialog Box).

Step 2 Click New to open the Discovery Job dialog box.

Step 3 Click the Virtual Machine Managers tab (see Virtual Machine Managers Tab).

Step 4 (Optional) To change the system-assigned job name, select the name and enter a new one.

Step 5 Perform one of the following tasks:

•To use the IP address or DNS name of a previously discovered virtual machine manager, check the Rediscover currently managed Virtual Machine Managers check box, then choose the virtual machine manager from the displayed list.

•In the IP Address/DNS Name field, enter the IP address or DNS name of the virtual machine manager.

Step 6 In the Type of Discovery group, click one of the following:

•Run Now—To start the discovery job immediately when you click OK.

•Schedule—To specify a schedule for the job to run it in the future. Choose the date and time when you want the job to run.

If you schedule the discovery job, you can also check the Enable Repeat check box to schedule the job to be rerun until you cancel the job. Choose the frequency time period (such as hour or day), and enter the number of time periods for the recurrence schedule. For example, choosing 2 Weeks causes the discovery job to be rerun every 2 weeks until canceled.

Step 7 Click OK.

VFrame creates a discovery job and adds it to the jobs list in the Discovery dialog box. When the job starts, you can view its progress in the upper pane. The messages generated during the job progress appear in the Job Logs pane (the lower pane).

If discovery is successful, the discovered virtual machine manager is displayed in the device selector on the Resources tab in the Virtual Machine Managers area.

If a device is unsupported, it appears in the Unsupported Devices area in the device selector on the Resources tab.

---

Next Step

After you discover the virtual machine managers, you can manage them (see the "Managing VirtualCenter" section on page 7-22).

Viewing the Discovery Status

You can view the status of discovery jobs in the Discovery dialog box. If there are a large number of jobs, you can filter the list to show only those jobs that interest you, such as those scheduled to run in the future or those currently running.

Procedure

---

Step 1 Choose Tools > Discovery to open the Discovery dialog box (see Discovery Dialog Box).

The upper pane includes a list of discovery jobs with summary information about each job.

To reduce the number of jobs displayed, click Filter, choose the job characteristics that interest you, and click OK. Jobs that do not satisfy the filter are not displayed.

Click Show All to remove the filter.

Step 2 To view the detailed log messages for a job, select the job in the upper pane. The log for the job appears in the Job Logs pane in the lower half of the window. The job log includes all messages returned during the job. It is continually updated for currently running jobs.

You can filter this list by selecting a severity level, which shows you only messages of the selected severity level.

Click the Task Results tab to view messages related to macro execution for LOM manager and storage manager discovery jobs.

Rescheduling or Unscheduling Discovery Jobs

You can reschedule or unschedule discovery jobs in the Discovery dialog box (choose Tools > Discovery). Changing the job schedule is typically done for jobs that are scheduled to recur, that is, to perform periodic rediscovery. Rediscovery updates the device inventory and identifies changes to resources that VFrame already knows about.

Your options for discovery job management are as follows:

•Reschedule—You can reschedule any job, even one that is not scheduled to repeat. Choose the job, and click Reschedule. You can then change any characteristic of the job. This activity is essentially the same as creating the initial discovery job, and in some cases rescheduling actually creates a new discovery job. For detailed information on creating discovery jobs, see the following topics:

–Discovering Ethernet Switches and Service Modules

–Discovering Storage Devices

–Discovering Servers

•Unschedule—You can unschedule any job that is scheduled to start at some future time. These jobs have the Scheduled status. Choose the desired job and click Unschedule. This prevents the job from running. If you change your mind, you can reschedule the job. Note that you cannot delete a discovery job after you create it.

Troubleshooting Discovery

This section describes some problems you might encounter when discovering devices and their solutions, and includes the following topics:

•You cannot discover the Ethernet switch.

•VFrame did not save the DHCP range that you just created.

•The switch port MAC address reported by SNMP is invalid.

•Service modules are getting module missing faults, but they are physically present and functional.

Problem   You cannot discover the Ethernet switch.

Solution   This problem can occur if you did not configure the SNMP credential (SNMPv2 read community string or the SNMPv3 user credential) on the physical switch. Configure the SNMP credentials on the switch, enter the same credentials in VFrame, then try to discover the switch again.

Problem   VFrame did not save the DHCP range that you just created.

Solution   This occurs if after entering the DHCP range in the DHCP Entry dialog box, you did not click the OK button in the DHCP dialog box. Even though the address range appears in the DHCP table, you must click the OK button in the DHCP dialog box to save your additions, deletions, or changes to the table.

Problem   The switch port MAC address reported by SNMP is invalid.

Solution   This occurs if the switch port that is connected to the server is down or is not associated with a VLAN. To resolve this, make sure that the switch port that is connected to the server is up, then run switch discovery again. The switch port configuration must contain the following commands:

switchport
switchport access vlan <vlan #>
no ip address

Make sure that the switch port configuration does not contain the shutdown command.

Problem   Service modules are getting module missing faults, but they are physically present and functional.

Solution   Check the SNMP community string settings on the switch. If you configured the same name for read and trap community strings, VFrame cannot identify that the discovery or inventory problem is the fact that VFrame does not have a valid SNMP read community string. Therefore, VFrame generates module missing faults. Re-enable the read community string. We recommend that you use unique read community strings, ones that are not the same as a trap community string. If you change the string name, you also need to update the device credentials in VFrame (choose Tools > Device Credentials).
