Setting The Host Mode And Host Group Mode For The Disk Array Ports; Setting The System Option Modes; Host Mode Setting 01 (Xp24000 Only) - HP StorageWorks XP24000 Configuration Manual

After these tasks are finished, you will use XP Remote Web Console, or XP LUN Manager to complete
the remaining tasks listed below. If you do not have these programs, your HP service representative
can perform these tasks for you.

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 disk array port to match the host
OS. Set the host mode using LUN Manager in XP Remote Web Console (shown). If these are 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 XP24000.
Figure 2 Host mode setting 01 (XP24000 only)
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 (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.

Setting the System Option Modes

The HP service representative sets the System Option Mode(s) based on the operating system and
software configuration of the host.
