Once the AIX installation is complete, depending on the SAN Storage box, you need to install the necessary subsystem driver and configure it. Now activate the AIX LPAR and install AIX in it, note that the minimum version required to support the NPIV feature is AIX 5.3 TL9 or AIX 6.1 TL2. Configure AIX Operating System to use multipath Make sure the slot numbers match with the slot numbers we have entered in the second VIOS LPAR while creating the Virtual FC Server Adapter.Ģ.3.2. Open the first VIOS’s profile for editing and navigate to the Virtual Adapters tab, click on Actions > Create > Fibre Channel Adapter as shown in the figure 2.1Ĭreate the second Virtual FC Client Adapter with the slot number details as shown the figure 2.6. This is because, for doing a Virtual FC Server Adapter to Client Adapter mapping both the VIOS and AIX LPAR should exist in the system, NOT like Virtual SCSI adapter mapping where you have to provide only the slot numbers and it does not check for the existence of the client.Ģ.2.1. NOTE : Before doing any NPIV related configuration, the VIOS and AIX LPAR profile configuration has to be completed with all the other details required for running the VIOS and the AIX LPAR, like proper Virtual SCSI adapter and/or Virtual Ethernet Adapter mapping, physical SCSI/RAID adapter mapping to the VIOS and/or AIX LPAR etc. 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.

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.
