Each VIOS should own at least 1 number of 8Gb FC Adapter (FC#5735) and one Virtual FC Server Adapter to map it to the client LPAR. You have to create dual VIOS instances on the System p server to avail maximum redundancy for the paths. AIX 6.1 Technology Level 02 or above 2.2.8Gb PCIe Dual-port FC Adapter (Feature Code #5735).IBM POWER6 or above processor based hardware.This lists only those pre-requisites for the AIX Operating System which are required for doing the Multipath This section explains the pre-requisites and the steps involved in configuring the multipath SAN connectivity for the The below given diagram ( Figure 1.1) shows the logical representation of the configuration explained in this document.įigure 1.1 2. NPIV allows System p logical partitions (LPARs) to have dedicated N_Port IDs, giving the OS a unique identity to the SAN, just as if it had a dedicated physical HBA(s).įor availing maximum redundancy for the SAN paths of the LPARs, the paths has to go through two different HBAs and those HBAs should be assigned to two different VIO Servers. On System p the Virtual I/O Server (VIOS) allows sharing of physical resources between LPARs including virtual SCSI, virtual Fibre Channel (NPIV) and virtual networking. An NPIV-capable fibre channel HBA can have multiple N_Port IDs, each with a unique identity and world wide port name. This allows multiple Fibre Channel initiators to occupy a single physical port, easing hardware requirements in Storage Area Network design.
N_Port ID Virtualization or NPIV is a Fibre Channel facility allowing multiple N_Port IDs to share a single physical N_Port.
