1. For Windows with any FC HBAs when MSCS is not needed.
2. For Windows with D8602 FC HBAs with or without MSCS.
3. For Windows with Emulex or QLogic FC HBAs with or without MSCS.
4. If you register Windows server hosts in a host group, verify that the host mode of the host group is 0C:
Windows or 2C: Windows Extension. If you are thinking about creating LUSE volumes, such as
expanded LUs, consider setting the host mode 2C: Windows Extension to the host group. If the host
mode is 0C: Windows and an LU path is defined for a volume, you cannot execute LUSE operations
on the volume without unmapping the volume first.
5. When registering Sun Cluster server hosts in the host group (Use this host mode both VERITAS Cluster
Server and Sun Cluster are used).

LUN Security

To protect data from unauthorized access, apply security policies to LUNs. LUN Manager can apply LUN
security to ports to safeguard LUs. If a port has the External attribute, you cannot apply LUN security to the
port.
NOTE: You cannot apply LUN security to NAS ports.
If LUN security is applied, it limits which host can access which LUs. A host can only access LUs associated
with its host group. Hosts cannot access LUs associated with other host groups.
In Figure 6, the hosts in the hpux-G01 group can access LUN0 and LUN1 associated with the same host
group, but cannot access LUN0 and LUN1 in the winG02 host group. The hosts in hpuxG01 can only
access the two LUs, identified by 01:05 and 02:01; the hosts cannot access the LUs 02:00 and 02:02.
