# vxdg -s import diskgroup
where diskgroup is the disk group name or ID. On subsequent cluster restarts, the
disk group is automatically imported as shared. Note that it can be necessary to
deport the disk group (using the vxdg deport diskgroup command) before
invoking the vxdg utility.
Forcibly importing a disk group
You can use the -f option to the vxdg command to import a disk group forcibly.
Warning: The force option(-f) must be used with caution and only if you are fully
aware of the consequences such as possible data corruption.
When a cluster is restarted, VxVM can refuse to auto-import a disk group for one
of the following reasons:
A disk in the disk group is no longer accessible because of hardware errors on
the disk. In this case, use the following command to forcibly reimport the disk
group:
# vxdg -s -f import diskgroup
Note: After a forced import, the data on the volumes may not be available and
some of the volumes may be in the disabled state.
Some of the disks in the shared disk group are not accessible, so the disk group
cannot access all of its disks. In this case, a forced import is unsafe and must
not be attempted because it can result in inconsistent mirrors.
Converting a disk group from shared to private
Shared disk groups can only be deported on the master node.
To convert a shared disk group to a private disk group, first deport it on the master
node using this command:
# vxdg deport diskgroup
Then reimport the disk group on any cluster node using this command:
# vxdg import diskgroup
