Host and Cluster Tasks
Activating a Shared Disk Group
Chapter 5228
When you have provided all necessary information in the dialog box,
click OK.
Step 4. To set the disk group activation mode on other nodes in the cluster,
access this task from the appropriate host machines and repeat this
procedure.
To give the current node read access for
volumes in the shared disk group, select
Shared Read. The current node cannot have
write access to the disk group, but other nodes
in the cluster may have write access.
Notes:
This task requires a disk group name.
In a cluster environment, you must specify the disk group activation
mode on a per-node basis.
The Exclusive Write, Shared Write, and Shared Read modes are only
applicable for shared disk groups in a cluster environment. The Read
Write mode is not available for shared disk groups.
For shared disk groups, the default activation mode is Off. For
non-shared disk groups, the default activation mode is Read Write.
Disk group activation settings are not persistent, so you may need to
reset the activation mode when you reboot the machine.
Disk group activation is only available on HP-UX systems.
