Linux and LVM Configuration
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 Server 2003/Windows 2000 and Dynamic Disk
Observe the following when using Windows Server 2003 dynamic disk:
• You cannot make a P-VOL and a V-VOL into a dynamic disk; however
you can use a P-VOL and a V-VOL as a dynamic disk.
• When using a V-VOL with a secondary host, insure that the pair status
is Split.
• 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.
• An LU, in which two or more dynamic disk volumes coexist, cannot be
copied.
• Do not use a dynamic disk function for volumes other than a V-VOL on
the secondary host side.
When copying, hide all the dynamic disks that exist on the primary side
using the
raidvchkset –vg idb
command. No restriction is placed on
the primary side. Hide all the dynamic disk volumes to be restored on
the primary side at the time of restoration.
