Disk Tasks
Activating Dynamic Disk Groups
Chapter 396
• In a cluster environment, you must specify the dynamic disk group
activation mode on a per-node basis.
• If your system supports a cluster environment, then the Exclusive
Write, Shared Write, and Shared Read modes are also applicable.
The Read Write mode is not available for shared dynamic disk
groups.
• For shared dynamic disk groups, the default activation mode is Off.
For non-shared dynamic 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 after rebooting the machine.
