Host Modes and Host Mode Options
The Universal Storage Platform V/VM supports connection of multiple server
hosts of different platforms to each of its ports. When your system is
configured, the hosts connected to each port are grouped by host group or by
target. For example, if Solaris and Windows hosts are connected to a fibre
port, a host group is created for the Solaris hosts, another host group is
created for the Windows hosts, and the appropriate host mode and host mode
options are assigned to each host group. The host modes and host mode
options provide enhanced compatibility with supported platforms and
environments.
The host groups, host modes, and host mode options are configured using the
LUN Manager software on Storage Navigator. For further information on host
groups, host modes, and host mode options, refer to the LUN Manager User’s
Guide (MK-96RD615).
