After these tasks are finished, use Remote Web Console, Command View Advanced Edition, or Array
Manager to complete the remaining disk array configuration tasks. If you do not have these programs,
your HP service representative can perform these tasks for you.

Defining the paths

Use Command View Advanced Edition or Remote Web Console to define paths between hosts and
volumes (LUNs) in the disk array.
This process is also called "LUN mapping." In the Remote Web Console, LUN mapping includes:
Configuring ports
Enabling LUN security on the ports
Creating host groups
Assigning Fibre Channel adapter WWNs to host groups
Mapping volumes (LDEVs) to host groups (by assigning LUNs)
In Command View Advanced Edition, LUN mapping includes:
Configuring ports
Creating storage groups
Mapping volumes and WWN/host access permissions to the storage groups
For details see the HP StorageWorks P9000 Provisioning for Open Systems User Guide . Note the
LUNs and their ports, WWNs, nicknames, and LDEVs for later use in verifying host and device
configuration.

Setting the host mode and host group mode for the disk array ports

After the disk array is installed, you must set the host mode for each host group that is configured on
a disk array port to match the host OS. Set the host mode using LUN Manager in Remote Web Console
or Command View Advanced Edition Software. If these are not available, the HP service representative
can set the host mode using the SVP. The host mode for AIX is 0F.
CAUTION:
The correct host mode must be set for all new installations (newly connected ports) to AIX hosts. Do
not select a mode other than 0F for AIX. Changing a host mode after the host has been connected is
disruptive and requires the server to be rebooted.
When a new host group is added, additional host group modes (options) may be configured. The
storage administrator must verify if an additional host group mode is required for the host group.
