Activating Dynamic Disk Groups

If supported on your platform, the Disk Groups Activation procedure sets the activation mode for a dynamic disk group. The dynamic disk group activation mode controls read and write access to volumes in the specified dynamic disk group.

Procedure 3-28 To activate a dynamic disk group

Select the dynamic disk group to be activated.
Choose Disk Groups > Activation.

Complete the Activate Disk Group dialog box as follows:

Disk Group Name:

Enter the name of the dynamic disk group to be activated.

Activation Mode:

Select one of the following dynamic disk group activation modes:

To disallow read and write access for volumes in the dynamic disk group, select Off.
To allow read and write access for volumes in the dynamic disk group, select Read Write.
To allow read only access for volumes in the dynamic disk group, select Read Only.

If your system supports a cluster environment, you can select one of the following additional options for shared dynamic disk groups:

To give the current node exclusive write access for volumes in the shared dynamic disk group, select Exclusive Write. No other nodes in the cluster can have write access to the dynamic disk group.
To give the current node write access for volumes in the shared dynamic disk group, select Shared Write. Other nodes in the cluster can share write access to this dynamic disk group.
To give the current node read access for volumes in the shared dynamic disk group, select Shared Read. The current node cannot have write access to the dynamic disk group, but other nodes in the cluster may have write access.

When you have provided all necessary information in the dialog box, click OK.




	NOTE: The Disk Groups Activation task requires a dynamic disk group name. 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.
