Volume Cleanup After completing the rootability cleanup, you must
determine which volumes need to be restored from backup. The volumes
to be restored include those with all mirrors (all copies of the volume)
residing on disks that have been reinstalled or removed. These volumes
are invalid and must be removed, recreated, and restored from backup. If
only some mirrors of a volume exist on reinitialized or removed disks,
these mirrors must be removed. The mirrors can be re-added later.
To restore the volumes, perform these steps:
Step 1. Establish which VM disks have been removed or reinstalled using the
following command:
# vxdisk list
The Volume Manager displays a list of system disk devices and the
status of these devices. For example, for a reinstalled system with three
disks and a reinstalled root disk, the output of the vxdisk list
command is similar to this:
DEVICE TYPE DISK GROUP STATUS
c0t0d0 simple - - error
c0t1d0 simple disk02 rootdg online
c0t2d0 simple disk03 rootdg online
- - disk01 rootdg failed was:
c0t0d0
NOTE Your system may use a device name that differs from the examples. For
more information on device names, see “Disk Devices”.
The display shows that the reinstalled root device, c0t0d0, is not
associated with a VM disk and is marked with a status of error. The
disks disk02 and disk03 were not involved in the reinstallation and are
recognized by the Volume Manager and associated with their devices
(c0t1d0 and c0t2d0). The former disk01, which was the VM disk
associated with the replaced disk device, is no longer associated with the
device (c0t0d0).
If other disks (with volumes or mirrors on them) had been removed or
replaced during reinstallation, those disks would also have a disk device
