You must configure the AIX operating system before you
can use IBM Power Systems hosts with the system.
Before you configure the AIX host operating systems, the following
tasks must be completed:
- The system must be installed.
- The appropriate host bus adapters must be installed.
After the prerequisite tasks are complete, use the following
general steps to configure your AIX host system.
- Zone the host to the system nodes on the Fibre Channel
SAN.
- Install the appropriate multipathing driver for your host
to enable the management of multiple paths to the system volumes.
Note: The Subsystem Device Driver (SDD) and the subsystem device driver path control module (SDDPCM) for
the AIX operating system support System pAIX host systems in a clustered-system
environment. To have failover protection on an open system, these
multipath drivers require a minimum of two Fibre Channel adapters.
The maximum number of Fibre Channel ports that are supported in a
single host (or logical partition) is four. This maximum number can
be four single-port adapters or two dual-port adapters or a combination.
The maximum number of ports that are attached to the system cannot
exceed four.
- On the system, create the host by using
the worldwide port names (WWPNs). Map the volume to the host.
- Create volumes and disks on your host by using instructions
in your host system publications.
