c. On the Host Groups screen, select a Host Group.
d. On the host group screen, select the Logical Units tab. Find
the identified H-LUN. The LUN displays in the next column.
e. If the HLUN is not present on a host group target screen, on
the Host Groups screen, select another Host group and repeat
Step d.
You cannot pair a P-VOL and V-VOL when their mapping information
has not been defined in the configuration definition file. To prevent a
host from recognizing a P-VOL or V-VOL, use LUN Manager to either
map them to a port that is not connected to the host or map them to
a host group that does not have a registered host. If you use Storage
Navigator instead of LUN Manager, you need only perform this task
with either the P-VOL or V-VOL.
Do not make the V-VOL an object of cluster or path switching
software.
• A host cannot recognize both a P-VOL and its V-VOL at the same
time. Map the P-VOL and V-VOL to separate hosts.
• When setting the V-VOL to be recognized by the host, use the
CCI mount command rather than Disk Administrator.
• Do not place the MSCS Quorum Disk in CCI.
• The command device cannot be shared between different hosts
in the cluster.
• Assign the exclusive command device to each host.
• A host cannot recognize both a P-VOL and its V-VOL at the same
time. Map the P-VOL and V-VOL to separate hosts.
• Multiple V-VOLs per P-VOL cannot be recognized from the same
host. Limit host recognition to one V-VOL.
A host cannot recognize both a P-VOL and its V-VOL at the same
time. Map the P-VOL and V-VOL to separate hosts.
• A P-VOL and S-VOL cannot be made into a dynamic disk on
Windows Server 2000.
