hg-hpux host group can access only two LUs (00:02:01 and 00:02:02). The two hosts in the
hg-solar host group can access only two LUs (00:01:05 and 00:01:06).
Disabling LUN security
Typically, you do not need to disable LUN security on ports. For example, if LUN security is disabled
on a port, the connected hosts can access only the LUs associated with host group 0, and cannot
access LUs associated with any other host group.
Host group 0 is the only host group reserved, by default, for each port. If you use the LUN Manager
window to view a list of host groups in a port, host group 0, indicated by 00, usually appears at
the top of the list.
The default name of host group 0 consists of the port name, a hyphen, and the number 00. For
example, the default name of host group 0 for port 1A is 1A-G00. However, you can change the
default name of the host group 0.
