Preparing the virtual Fibre Channel configuration for partition mobility

You need to verify that the virtual Fibre Channel configuration is configured correctly so that you can successfully migrate the mobile partition from the source server to the destination server by using the Hardware Management Console (HMC).

Before you plan an inactive partition migration on a logical partition that has an N_Port ID Virtualization (NPIV) adapter, you must ensure that the logical partition had been activated at least once.
The verification includes tasks such as verifying the worldwide port names (WWPNs) of the virtual Fibre Channel adapters on the mobile partition, and verifying that the physical Fibre Channel adapters and the physical Fibre Channel switches support NPIV. AIX® NPIV clients using AIX Multipath I/O (MPIO) software support single path reserve with live partition mobility.

You can migrate a client partition that has mapped NPIV adapters for which no WWPN targets have been zoned, by specifying the Fibre Channel port to be used on the destination partition. If the physical port which must be used on the destination partition is specified, validation checks the physical port to ensure that it has no WWPN targets that are zoned and that the virtual adapter is mapped on the destination partition. When the physical port is not specified, validation checks all ports on the destination partition to determine whether there are any WWPN targets that are zoned. If any WWPN targets that are zoned are found, the validation fails. If there are no WWPN targets that are zoned, the virtual adapter is not mapped on the destination partition.

The destination server must provide the same virtual Fibre Channel configuration as the source server so that the mobile partition can access its physical storage on the storage area network (SAN) after it migrates to the destination server.

To prepare the virtual Fibre Channel configuration for active or inactive partition mobility, complete the following tasks.

Table 1. Preparation tasks for the virtual Fibre Channel configuration on systems that are managed by the HMC
Storage planning tasks Active mobility task Inactive mobility task Information resources
1. For each virtual Fibre Channel adapter on the mobile partition, verify that both the (active and inactive) WWPNs are assigned to the same set of logical unit numbers (LUNs) and zoned to the same storage port worldwide name (WWN) on the SAN. X X
2. Verify that the physical Fibre Channel adapters that are assigned to the source and destination Virtual I/O Server logical partitions support NPIV. Run the lsnports command to view the physical ports on the physical Fibre Channel adapters that support NPIV. X X Virtual I/O Server and Integrated Virtualization Manager commands
3. Verify that the switches to which the physical Fibre Channel adapters on both the source and destination Virtual I/O Server logical partitions are cabled support NPIV. Run the lsnports command to view the fabric support of the physical ports on the physical Fibre Channel adapters. If the fabric support is 1, the physical port is cabled to a switch that supports NPIV. X X Virtual I/O Server and Integrated Virtualization Manager commands
4. Verify that the mobile partition has access to the virtual Fibre Channel adapters on the source Virtual I/O Server logical partition. X X Verifying the virtual adapter connections between the mobile partition and the Virtual I/O Server logical partitions on the source server
5. If you changed any partition profile attributes, restart the mobile partition for the new values to take effect. X X Shutting down and restarting logical partitions
