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.

You can also use this operation to re-scan a disk that may have
been changed outside of the Volume Manager. For example, if a
disk is shared between two systems, the Volume Manager running
on the other system may have changed the disk. If so, you can
use this operation to re-scan the disk.
NOTE: Many vxdiskadm operations re-scan disks without user
intervention. This will eliminate most needs to online a
disk directly, except when the disk is directly offlined.
