If you move a disk from one system to another during normal system operation, VxVM does not recognize the disk automatically. The enable disk task enables VxVM to identify the disk and to determine if this disk is part of a disk group. Also, this task re-enables access to a disk that was disabled by either the disk group deport task or the disk device disable (offline) task.
To enable a disk
Select a disk device to enable [<address>,list,q,?] c0t2d0
Enable another device? [y,n,q,?] (default: n)
# vxdctl enable
# vxreattach -r accesname
where accessname is the disk access name (such as c0t1d0). This initiates the recovery of all the volumes on the disks. Alternatively, halt the cluster, reboot all the cluster nodes, and restart the cluster. If you do not perform this step for a cluster, the nodes may not be able to see the disks, and the error
Device path not valid will be displayed.
