Setting The Host Mode And Host Group Mode For The Disk Array Ports - HP StorageWorks P9000 Configuration Manual

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 Command View Advanced Edition. The host mode setting for Solaris is 09.
CAUTION:
to Solaris hosts. Do not select a mode other than 09 for Solaris. 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) can be configured. The
storage administrator must verify if an additional host group mode is required for the host group.
For Solaris, host group mode 7 should always be set because this is a prerequisite when using the
Oracle SAN driver.
The following host group modes (options) are available for Solaris:
