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

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 more information about LUN mapping, see the HP StorageWorks P9000 Provisioning for Open
Systems User Guide or Remote Web Console online help. Note the LUNs and their ports, WWNs,
nicknames, and LDEVs for later use in verifying host and device configuration.
IMPORTANT:
for a Windows server (00 to FE) and will not be recognized by the server or be visible for use.
Windows 2000: A LUN 0 must be created to discover more than LUNs 0 to 7.

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

After the disk array is installed, 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. If these are not available, the HP service representative can
set the host mode using the SVP.
The available host mode settings are as follows:
Table 7 Host mode settings (Windows)
Host mode
2C (available on some array
models)
0C
Table 8 Volume names for host mode setting (Windows)
Volume on P9000 array (examples)
OPEN-E
OPEN-9
OPEN-9*2
OPEN-9*3-CVS
CAUTION:
to Windows hosts. Do not select a mode other than 2C or 0C. Changing a host mode after the
host is connected is disruptive and requires a server reboot.
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.
The following host group modes (options) are available for Windows:
A LUN assigned a number greater than FF is outside the accepted range of numbers
