Caching storage data in NPIV mode
In this mode, the cache device is available as a virtual Fibre Channel (N_Port ID Virtualization) device on the AIX® logical partition (LPAR).
You must create a cache pool, and then a cache partition on the AIX LPAR. Only one cache partition can be created on the AIX LPAR. You can use the cache partition to cache any number of target devices on the AIX LPAR. The LPAR can be migrated to another server because the cache device is available from the storage area network (SAN). The cache device must be made visible on the destination system. The caching operation can continue during the migration process, and the cache will be populated after the migration completes.
Caching the target device in NPIV mode is same as caching the storage data in dedicated mode except that the cache device is available from the SAN. However, the procedure to cache the target device is same as caching the storage data in dedicated mode.
