If you are installing Veritas Volume Manager for the first time or adding disks to an existing cluster, you need to configure new shared disks.
If you are setting up Veritas Volume Manager for the first time, configure the shared disks using the following steps in the specified order:
Start the cluster on one node only to prevent access by other nodes.
On one node, run the vxdiskadm program and choose option 1 to initialize new disks. When asked to add these disks to a disk group, choose none to leave the disks for future use.
On other nodes in the cluster, run vxdctl enable to see the newly initialized disks.
Use the vxdg command or the Veritas Operations Manager (VOM) to create disk groups. If you use the vxdg command, specify the -s option to create shared disk groups.
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.
