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) or XP 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 NonStop is 0C or 2C. Use host mode 2C if you plan to use LUN size expansion (LUSE). CAUTION: The correct host mode must be set for all new installations (newly connected ports) to NonStop hosts. Do not select a mode other than 0C or 2C for NonStop. 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. CAUTION: Changing host group modes for ports where servers are already installed and configured is disruptive and requires the server to be rebooted. 10 Installing and configuring NonStop for the XP disk array

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) or XP 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 NonStop is
0C
or
2C
. Use host mode 2C if you plan to use LUN size expansion (LUSE).
CAUTION:
The correct host mode must be set for all new installations (newly connected ports) to NonStop hosts.
Do not select a mode other than
0C
or
2C
for NonStop. 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.
CAUTION:
Changing host group modes for ports where servers are already installed and configured is disruptive
and requires the server to be rebooted.
