You must configure the AIX® operating
system before you can use IBM® System p® hosts with the SAN Volume Controller.
Before you configure the AIX host
operating systems, the following tasks must be completed:
- The IBM service
representative must
have installed the SAN Volume Controller.
- You must have installed the appropriate host bus adapters.
After the prerequisite tasks are complete, use the following
general steps to configure your AIX host
system.
- Zone the host system to the SAN Volume Controller on
the fibre-channel SAN.
- Install the appropriate multipathing driver for your host
system to enable the management of multiple paths to SAN Volume Controller virtual
disks (VDisks).
Note: The subsystem
device driver (SDD) and
the subsystem device driver path control module (SDDPCM) for the AIX operating system support System p AIX host systems in a clustering 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 can be four single-port
adapters or two dual-port adapters or a combination, as long as the
maximum number of ports that are attached to the SAN Volume Controller does
not exceed four.
- Create the host system on the SAN Volume Controller, using the worldwide port names (WWPNs). Map the VDisks
to the host as required.
- Create volumes/disks on your host using instructions in
your host system publications.
