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.
To display disk information, use the following procedure:
Step 1. Start the vxdiskadm program, and select list (List disk information) from
the main menu.
