Importing Dynamic Disk Groups
The Import Dynamic Disk Group procedure makes a deported (inaccessible) dynamic
disk group and its volumes accessible again. To import a deported dynamic disk group,
you must know the former name of the dynamic diskgroup, and this name must not bein
use. In addition, at least one disk name formerly assigned to the deported dynamic disk
group must not be in use.
▼ To import a dynamic disk group
1. Select the appropriate host machine node.
2. Choose Actions > Import Dynamic Disk Group.
3. Complete the Import Dynamic Disk Group dialog box as follows:
When you have provided all necessary information in the dialog box, click OK.
New Name: Enter a new dynamic disk group name in the New Name field. to
change the name of the dynamic disk group at import.
Clear host ID Select
Clear host ID to clear the existing host ID stamp on all
disks in the dynamic disk groupat import,Donot usethisoptionif
another host is using any disks in the dynamic disk group.
Force Select
Force to force the dynamic disk group import when the
host cannot access all disks in the dynamic disk group This option
can be used to import a dynamic disk group that contains a failed
disk, but can lead to dynamic disk group inconsistency if all disks
are still usable.
Notes:
◆ Only deported dynamic disk groups can be imported.
◆ A deported dynamic disk group cannot be imported if another dynamic disk group with
the same name has been created since the dynamic disk group was deported.
◆ When a dynamic disk group is imported, the system stamps its host ID on all disks in the
dynamic disk group. A dynamic disk group import fails 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 twosystemsatthesametime.If youaresurethat
the dynamic disk group is not in use by another host, you can clear the host IDs and
import the dynamic disk group by selecting the
Clear host ID option.
