Some systems have the boot disk encapsulated in Veritas and it is mirrored

This volume should have at least two plexes, so there are plexes currently disabled on this disk group.
root@solaris:/ # vxprint -htg rootdg | grep DISABLED
pl local-02 – DISABLED – 6292242 CONCAT – RW

To attach this plex to the volume type the command below
root@solaris:/ # vxplex -g rootdg att rootvol rootvol-02
Veritas will not release the shell until it completes the task. Open another terminal and type vxtask list to check the status
root@solaris:/ # vxtask list

After it is finished, check the volume again. It should have two plexes like in the example below
