Displaying Disk Information
Before you use a disk, you need to know if it has been initialized and
placed under VxVM control. You also need to know if the disk is part of a
disk group because you cannot create volumes on a disk that is not part
of a disk group. The vxdisk list command displays device names for all
recognized disks, the disk names, the disk group names associated with
each disk, and the status of each disk.
To display information on all disks that are known to VxVM, use the
following command:
# vxdisk list
VxVM returns a display similar to the following:
DEVICE TYPE DISK GROUP STATUS
c0t0d0 sliced disk04 rootdg online
c1t0d0 sliced disk03 rootdg online
c1t1d0 sliced - - online invalid
enc0_2 sliced disk02 rootdg online
enc0_3 sliced disk05 rootdg online
enc0_0 sliced - - online
enc0_1 sliced - - online
NOTE The phrase online invalid in the STATUS line indicates that a disk has
not yet been added to VxVM control. These disks may or may not have
been initialized by VxVM previously. Disks that are listed as online are
already under VxVM control.
To display details on a particular disk defined to VxVM, use the following
command:
# vxdisk list diskname
Displaying Disk Information with vxdiskadm
Displaying disk information shows you which disks are initialized, to
which disk groups they belong, and the disk status. The list command
displays device names for all recognized disks, the disk names, the disk
group names associated with each disk, and the status of each disk.
