Setting The Host Mode And Host Group Mode For The Disk Array Ports; Host Mode Setting 01 (Xp20000/Xp24000 Only) - HP XP20000/XP24000 Configuration Manual

For details see the HP StorageWorks XP LUN Manager User s 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 XP Remote Web
Console (shown). If XP Remote Web Console is not available, the HP service representative can set
the host mode using the SVP. The host mode setting for VMware is 0C for the XP10000/XP12000
and 01 for the XP20000/XP24000.

.
CAUTION:
The correct host mode must be set for all new installations (newly connected ports) to VMware hosts.
Do not select a mode other than 0C (XP10000/XP12000) or 01 (XP20000/XP24000) for VMware.
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 (host mode options) may be configured.
The storage administrator must verify if an additional host group mode is required for the host group.
IMPORTANT:
HP recommends selecting host group mode 19 (processing time for reserve commands during I/O
processing is shortened). Your HP representative will select host group mode 19 for you.
CAUTION:
Changing host group modes for ports where servers are already installed and configured is disruptive
and requires the server to be rebooted.
