Converting existing VxVM disk groups to shared disk groups�
Use this procedure if you are upgrading from VxVM 3.x to VxVM 5.0 (or Storage
Foundation 3.x to a Storage Foundation product at the 5.0 level) and you want to
convert existing disk groups to shared disk groups.
To convert existing disk groups to shared disk groups�
1
Start the cluster on at least one node.
For a two-node cluster, start the cluster on one node; for a four-node
cluster, start the cluster on three nodes.
2
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.
3
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.
