# 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.
CAUTION 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
• Some of the nodes to which disks in the disk group are attached are
not currently in the cluster, 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
NOTE 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
