HP XP20000/XP24000 Configuration Manual page 89

CAUTION: The correct host mode must be set for all new installations (newly connected ports)
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:
