If you register Windows server hosts in a host group, ensure that the host group’s host mode is 0C Windows or 2C Windows
Extension. If you are thinking about creating LUSE volumes (that is, expanded LUs), consider setting the host group’s host mode
to 2C Windows Extension.
If the host group’s host mode is 0C Windows and an LU path is defined between the host group and a logical volume, you
cannot combine the logical volume with other logical volumes to form a LUSE volume (that is, an expanded LU). For more
information about LUSE, see
Overview of Volume Manager and Custom Volume Size .
If the host mode of a host group is 0C: Windows and an LU path is defined between the host group
and a logical volume, you cannot combine the logical volume with other logical volumes to form a
LUSE volume (that is, an expanded LU).
If you are using any VERITAS products: I/O fencing function of VERITAS Cluster Server 4.0, VERITAS
DataBase Edition/Active Cluster, VERITAS Storage Foundation for Oracle RAC, you must select this
host mode. When selecting a host mode, you must consider the platform and some other factors.
