Dynamic disk group join
This section describes the procedures for a dynamic disk group join operation.
When you join two dynamic disk groups, the disk group you designate as the source becomes the one that loses its identity in the merge. The target dynamic disk group is the one that remains after the merge.
Storage Foundation allows a partial join - that is, volumes in the source disk group can have missing or nonfunctional disks and the join command can still succeed.
The disk group type after the join becomes the type of the target disk group. For example, if the target disk group before the join had private dynamic disk group protection, the combined disk group has private dynamic disk group protection after the join.
Note:
A cluster dynamic disk group that is part of the cluster resources cannot be a source disk group for a join command. However, it can be a target disk group for the command.
Note:
It is possible to force the join command when a volume is in use or if disks from the source disk group's disks are missing, but this is not recommended as a best practice.
Note:
Microsoft Disk Management Disk Groups do not support dynamic disk group join.
To join two disk groups into one disk group:
- Make sure that the volumes in the source dynamic disk group are not in use and are healthy.
- Right-click the disk group object in the left pane of the VEA console, and then click the Join Dynamic Disk Group command, or select the Join Dynamic Disk Group command from the Actions menu on the VEA console menu bar.
- In the Join Dynamic Disk Group dialog box, make sure that the correct source and target disk groups are indicated. If necessary, use the drop-down lists to change the disk group names.
The source dynamic disk group is the disk group that is merged with the target dynamic disk group. The source disk group ceases to exist after the join.
The target dynamic disk group is the disk group that remains after the join. It retains its identity and becomes larger with the addition of the disks from the source disk group.
The Clear host ID check box should be used when you want to import a disk group from another node and that disk group was not properly deported. A host ID might not be cleared, for example, if the host computer became nonfunctional. When a host ID has not been cleared, SFW does not permit the join without the Clear host ID override. Use this override with care.
The Allow Partial Join check box can be used when you have a missing or nonfunctional disk or disks in the source disk group and you want SFW to allow the join to occur.
See See About partial disk group join.
- Click OK.
If the join operation is successful, the source dynamic disk group merges into the target dynamic disk group. The changes in the target dynamic disk group are reflected in the VEA console tree view and the right pane.
If a volume is in use, SFW displays an error message about forcing the join command.
If there is an error message about the disks not being ready, you can click the check box for the partial join to allow the command to complete.
If the join operation fails, an error dialog box is displayed, showing the reason for the failure.
The new dynamic disk group after the join command are of the same type as the target dynamic disk group. For example, if a cluster dynamic disk group is joined with a normal dynamic disk group, then the new dynamic disk group is a normal dynamic disk group.
