Veritas Storage Foundation 5.1 SP1 Cluster File System Installation Guide (5900-1510, April 2011)

Converting existing VxVM disk groups to shared disk groups
Use this procedure if you are upgrading from VxVM 3.x to VxVM 5.1 SP1 (or
Storage Foundation 3.x to a Storage Foundation product at the 5.1 SP1 level) and
you want to convert existing disk groups to shared disk groups.
If you want to convert existing private disk groups to shared disk groups, use the
following procedure. Use these steps if you are moving from a single node to a
cluster, or if you are already in a cluster and have existing private disk groups.
To convert existing disk groups to shared disk groups
1
Ensure that all systems that are running are part of the same cluster.
2
Start the cluster on all of the nodes on which you are converting the disk
groups.
3
Configure the disk groups using the following procedure.
To list all disk groups, use the following command:
# vxdg list
To deport disk groups to be shared, use the following command:
# vxdg deport disk_group_name
To import disk groups to be shared, use the following command on the master
node:
# vxdg -s import disk_group_name
This procedure marks the disks in the shared disk groups as shared and
stamps them with the ID of the cluster, enabling other nodes to recognize
the shared disks.
If dirty region logs exist, ensure they are active. If not, replace them with
larger ones.
To display the shared flag for all the shared disk groups, use the following
command:
# vxdg list
The disk groups are now ready to be shared.
4
If the cluster is only running with one node, bring up the other cluster nodes.
Enter the vxdg list command on each node to display the shared disk groups.
This command displays the same list of shared disk groups displayed earlier.
