Support for N_Port ID Virtualization (NPIV) in IBM Virtual I/O Server (VIOS) environments
SFHA Solutions support N_Port ID Virtualization (NPIV) in IBM Virtual I/O Server (VIOS) environments:
The VIOS is configured with NPIV capable Fibre Channel (FC) adapters that are connected to a SAN switch that is NPIV capable.
The LUNs mapped to the VIO client behave like an LPAR with a dedicated FC adapter.
The devices in the VIO client appear as regular SCSI disks, which Storage Foundation can access. Unlike in the classic VIO environment without NPIV, Storage Foundation treats these devices as if they came from a regular SAN storage array.
With NPIV, the VIO client environment is transparent to Storage Foundation. All of the Storage Foundation commands would have the same output as in a regular physical AIX server.
You can create and import disk groups on NPIV devices, which provide access to volumes and file systems.
Veritas has qualified NPIV support with Storage Foundation.
Veritas has also qualified migration of storage used by Storage Foundation from the AIX physical server environment to the IBM VIO environment.
Table: Veritas InfoScale products NPIV support
Veritas InfoScale components | NPIV support |
---|---|
Storage Foundation | Storage Foundation 7.4.1 supports all functionality available with dedicated HBAs when using LUNs presented through NPIV. All IBM supported NPIV enabled HBAs are supported by Storage Foundation. |
Storage Foundation Cluster File System High Availability (SFCFS HA) | SFCFSHA is supported with NPIV. |
Cluster Server (VCS) | VCS supports NPIV. With NPIV, the VIOS client environment is transparent to VCS and the LUNs are treated as regular SAN storage array LUNs. Since SCSI3 persistent reserve is available, I/O fencing is also supported. |
