You must configure the Virtual I/O Server and the IBM® i client
operating system before you can use IBM i as
a host with the SAN Volume Controller.
Before you configure the 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 adapter and driver
on your host system.
After the prerequisite tasks are complete, use the following
general steps to configure your host operating system:
- Zone the Virtual I/O Server to the SAN Volume Controller on
the fibre-channel SAN.
- Install the SAN Volume Controller subsystem
device driver path-control module (SDDPCM) on the Virtual I/O Server
to enable the management of multiple paths to the SAN Volume Controller virtual
disks (VDisks).
- Create the host system on the SAN Volume Controllerusing
the worldwide port names (WWPNs). Map the VDisks to the host as required.
Note: The IBM i virtual
I/O client supports startup from a SAN with a virtual disk for the
load source of 20 GB or larger.
- Run the cfgdev command on the Virtual I/O Server
to configure the new disks. Use the lspath command
to ensure that disks are enlisted to all paths to the SAN Volume Controller.
- Map the SAN Volume Controller LUNs
(hdisks on the Virtual I/O Server) uniquely to the IBM i virtual
SCSI client adapters using the mkvdev command.
- Ensure on the Hardware Management Console (HMC) that the I/O tagging
for the IBM i virtual
I/O client partition is correctly set for the load source and the
alternate restart device.
- Start installing IBM i version
6 release 1 or later.
