This feature can be used if you have made changes to Fibre Channel port pools or have added an additional server switch with an Fibre Channel gateway.
The distribution of WWNs will automatically be allocated in the most serviceable distribution possible with the given devices. For example, if a port group is created across two server switches, the WWNs would be distributed over the separate chassis.
Viewing and Managing VFrame Director Networks
The Network tab in the VFrame Directors menu provides information that applies to both VFrame Directors (if multiple VFrame Directors are configured).
Use the Network tab for the VFrame Directors to create the following interfaces:
•In single-instance mode (where only a single VFrame Director is used):
–An interface for your power management (such as eth0)
•In high availability mode (where two VFrame Directors are used):
–An interface for your power management
–An interface for heartbeat 1 (such as eth1) between the VFrame Directors
–An interface for heartbeat 2 (such as ib0) between the VFrame Directors
In addition, the VFrame Directors must be associated with at least one management interface, created through the Assets > Network menu. See the "Configuring a Management Interface in the GUI" section on page 3-9, for details.
These topics describe how to perform the tasks:
•Viewing VFrame Director Network Information
•Adding a VFrame Director Network Interface
•Deleting a VFrame Director Network Interface

Figure 10-14 Configure or Change Shared Storage for VFrame Directors
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 choose to override this protection.
Step 6 Check the Assigned box next to the LUN that you want to assign to be the database for the active and standby VFrame Directors. If you are using an active/passive storage array, make sure that the LUN you choose is on the active path.
If you are using multipathing software such as PowerPath, you can assign all paths to a given LUN up to the number of paths supported by your PowerPath licence.
You cannot check boxes in this column that are dimmed. These LUNs have already been assigned to other virtual servers. You can override this restriction in the "Allow collection of storage assigned to another virtual server" field by clicking the Yes button.
Caution VFrame will move data from the local disk on the VFrame Director to this LUN, and will partition the device in the process. Make sure that the data LUN does not have data on it, because you will lose any existing data on the LUN.
Step 7 Enter a description of the shared LUN in the Description field. This text should be a description that helps identify what the LUN is being used for, such as Shared LUN for VFrame Database.
Step 8 View the size of the LUN in the Size field.
Step 9 Enter 0 in the Device ID field to use this LUN as a shared data LUN for the active and standby VFrame Director database.
Step 10 Click the Apply button to save changes.
Step 11 Click the Cancel button to return to the storage view without saving changes.

Step 6 View the description assigned to the Fibre Channel port pool in the Pool Description field. Refer to the "Viewing Fibre Channel Port Pools" section on page 9-8 to edit an Fibre Channel port pool description.
Step 7 View the number of Fibre Channel ports assigned to an Fibre Channel port pool in the Pool Size field. The pool size refers to all of the ports assigned to the pool, but you do not have to allow the VFrame Director to use all of those ports (restrict access in the #WWPNs field).
Refer to the "Viewing Fibre Channel Port Pools" section on page 9-8 to add or subtract Fibre Channel ports in an Fibre Channel port pool.
Step 8 View or enter the number of WWPNs for the active and standby VFrame Directors in the # WWPNs field. For two-port Fibre Channel gateways, one port from the pool is allocated for each WWPN. For example, if your pool of Fibre Channel ports contains four ports total, you can choose to use all four possible WWPNs, or you can choose to allocate fewer WWPNs to the VFrame Directors.
If you enter a value into the # WWPNs field that is greater than the number of available ports in the Pool Size field, you will simply have extra unused WWPNs. These unused WWPNs can be useful if you plan to add Fibre Channel gateways in the future, and want to have the WWPNs zoned in advance.
For four-port Fibre Channel gateways, each WWPN allocates all four ports on the gateway.
Note All currently supported Fibre Channel gateways have two ports only.
An entry of 0 means that the VFrame Directors will not have access to storage.
Step 9 Click Apply to save changes to the number of accessible WWPNs for the VFrame Director.
Step 10 Click the Refresh button to update the information in the window.
Configuring VFrame Directors for High Availability
The High Availability tab is used to configure the high-availability network for redundant VFrame Directors. Before configuring the High Availability tab, you should have installed VFrame on a redundant VFrame Director, configured two interfaces for heartbeats, and obtained a public IP address for the virtual IP address.
To configure VFrame Directors for high availability, follow these steps:

Figure 10-17 VFrame Director High Availability Tab—High Availability Configured
Step 4 Verify the name of the host that is currently the active VFrame Director in the Active Director field.
The name in this field must match the hostname returned in the uname -n command. If the hostname is different from the one in the Active Director field, change the hostname in the physical server menu. See the "Viewing and Modifying Physical Server Details" section on page 9-34.
Step 5 Verify the name of the host that is currently the standby VFrame Director in the Standby Director field. This field is blank if high availability is not configured. The name in this field must match the hostname returned in the uname -n command. If the hostname is different from the one shown in the Standby Director field, change the hostname in the physical server menu. See the "Viewing and Modifying Physical Server Details" section on page 9-34.
Step 6 View the status of the high availability feature in the High Availability Mode field. The field displays Enabled when the high availability configuration is complete.
Step 7 View the status of a redundant VFrame Director (if one is being used) in the Standby Director Status field. Click the Auto Recover Standby button to perform auto-recovery on a standby VFrame Director in a faulty state.
Step 8 Click the Auto Recover Standby radio buttons to turn the auto-recover feature on or off.
This feature is on by default, allowing an active VFrame Director to attempt to recover a standby VFrame Director after a failover event. However, you can choose to temporarily disable this feature under certain circumstances, such as during an upgrade. Refer to the "Understanding Auto-Recovery" section on page 1-8 for more information.
Step 9 View the Multipathing Status field to determine the state of multipathing to the data LUN on the VFrame Director as shown in Table 10-1.
Table 10-1 Multipathing Status Field Values
Status
|
Meaning
|
OK
|
Multipathing is enabled and all paths to the data LUNs are up.
|
Paths Down
|
Multipathing is enabled, but some paths to the LUN are down. Path redundancy is compromised.
|
Insufficient Paths Configured
|
Multipathing is enabled, however, only one path to the data LUN is configured. There is no path redundancy.
|
Driver Not Installed
|
Multipathing is disabled because multipathing software is not installed.
|
Step 10 View, edit, or enter the virtual IP address in the HA Cluster virtual IP field.
This is a public address that "floats" between the VFrame Directors so that it belongs to whichever VFrame Director is the active VFrame Director. Once this IP address is configured and the heartbeat is started, as described in the "Starting VFrame Director Heartbeats and High Availability Mode without PowerPath Install" section on page 4-24, you should use this new virtual IP address to contact the VFrame Director.
Step 11 From the VFrame data LUN drop-down menu, choose the LUN/target pair for the VFrame database.
Step 12 From the VFrame heartbeat IP1 drop-down menu, choose the interface for the first heartbeat.
Step 13 From the VFrame heartbeat IP2 drop-down menu, choose the interface for the second heartbeat.
Step 14 Click the Apply button to save any changes.
Step 15 Click the Refresh button to update the information in the window.
Step 16 Click the Fail-over now button to change the active VFrame Director host to the current standby host. This action causes the standby VFrame Director to become the new active VFrame Director.
Note The failover procedure cannot be tested until you have started VFrame in HA mode. Refer to the "Starting VFrame Director Heartbeats and High Availability Mode without PowerPath Install" section on page 4-24.
If auto-recover has not been disabled, the new active VFrame Director will attempt to reboot the redundant VFrame Director and reestablish connection. Refer to the "Understanding Auto-Recovery" section on page 1-8 for more information.
Step 17 Click the Recover Standby button to manually initiate the auto-recover process. Auto-recover reboots and attempts to reestablish connection with a standby VFrame Director. This function can be triggered automatically by a failover event or manually by clicking the Recover Standby button.
The Auto Recover Standby field must be set to On for auto-recover to function. Refer to the "Understanding Auto-Recovery" section on page 1-8 for more information.
Step 18 Click the Configure and Check HA button to save the high-availability configuration. The system verifies whether you have configured all the necessary fields. Click the Configure and Check HA button any time a change is made to the VFrame Director configuration.
