Prerequisites for unallocating volumes from hosts
Volume unallocation frees up volumes for reallocation to other systems needing these resources.
Before unallocating volumes, verify the following:
• The host and storage systems are registered in HP StorageWorks P9000 Command View Advanced
Edition Suite software.
• The IT administrator has unmounted the volumes you plan to unallocate.
In addition, determine:
• The host name
• The volume for unallocation
CAUTION:
When you unallocate a volume, the information stored on it is no longer accessible. To retain this
data, back this volume up before unallocating.
Unallocating volumes from hosts
Volume unallocation frees up host volumes for reallocation to other systems needing these resources.
Before you unallocate volumes, review “ Prerequisites for unallocating volumes from hosts ” on page 68.
1. From the Resources tab, select Hosts.
2. Expand the tree and select the target OS.
3. From the list of hosts, select one or more hosts from which you want to unallocate all volumes,
and then click the Unallocate Volumes button. If you want to unallocate specific volumes, click
the link of the host name to select the target volumes, and then click the Unallocate Volumes button.
4. If the displayed volumes are correct, unallocate the volumes with the appropriate options.
5. In the task list, confirm that the task has completed.
When the unallocation completes, the data stored on the volume is no longer accessible. You can
then allocate the volume to another host.
Replicating volumes
This module describes how to replicate volumes.
About replicating volumes (pair management)
Volume replication is used to make copies of critical data for volumes allocated to hosts. You can
make a local copy of a volume in the same storage system, or make a remote copy of a volume in a
different storage system.
Device Manager uses a light version of Replication Manager which allows you to perform basic
volume replication operations.
To use the complete Replication Manager functionality, you must register a Replication Manager
license and log in to Command View AE Suite with Replication Manager permissions. When you
