Importing a Disk Group

To start all volumes in the disk group at import, select Start All Volumes.

To clear the existing host ID stamp on all disks in the disk group at import, select Clear Host ID. Do not use this option if another host is using any disk(s) in the disk group.

To force the disk group import when the host cannot access all disks in the disk group, select Force Import. This option can be used to import a disk group that contains a failed disk, but can lead to disk group inconsistency if all disks are still usable.

To import the disk group as a shared disk group, select Import Shared. This option is only applicable in a cluster environment.

To change the name of the disk group at import, type a new disk group name in the New Name field. To indicate that the name change is temporary, select Use New Name as Temporary.

This task requires a disk group name.

Only deported disk groups can be imported.

A deported disk group cannot be imported if another disk group with the same name has been created since the disk group was deported.

A disk group import may fail if the host cannot find one or more disks in the disk group. If the import fails because a disk has failed, you can import the disk group by selecting the Force Import option. If the import fails for another reason, a forced import can cause serious problems.

When a disk group is imported, the system stamps its host ID on all disks in the disk group. A disk group import should fail if one of the disks is stamped with a host ID that does not match the others. This ensures that dual-ported disks cannot be managed (and possibly corrupted) by two systems at the same time. If you are sure that the disk group is not in use by another host, you can clear the host IDs and import the disk group by selecting the Clear Host ID option.
