Cluster Software, Path Switching Software
Do not make the V-VOL an object of the cluster software and the path
switching software.
Microsoft Cluster Server (MSCS)
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.
Veritas Volume Manager (VxVM)
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.
Windows 2000
Multiple V-VOLs per P-VOL cannot be recognized from the same host. Limit
host recognition to one V-VOL.
Windows Server 2003
• Multiple V-VOLs per P-VOL cannot be recognized from the same host.
Limit host recognition to one V-VOL.
• When mounting volumes, must use the CCI mount command. Do not
use mountvol command that is included in Windows Server 2003 by
standard. Please install CCI on the server on which the mount command
is to be executed. For more information, see the Hitachi Simple Modular
Storage Command Control Interface (CCI) Reference Guide.
• When using CCI, if a path fails for more than one minute, the command
device may not be recognized when the path is recovered. Execute
Windows’ “re-scan the disks” to make recovery. Restart CCI if Windows
cannot access the command device even if CCI is able to recognize it.
