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
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
VxVM returns a display similar to the following:
DEVICE TYPE DISK GROUP STATUS
c0t0d0 auto:hpdisk mydg04 mydg online
c1t0d0 auto:hpdisk mydg03 mydg online
c1t1d0 auto:hpdisk - - online invalid
enc0_2 auto:hpdisk mydg02 mydg online
enc0_3 auto:hpdisk mydg05 mydg online
enc0_0 auto:hpdisk - - online
enc0_1 auto:hpdisk - - online
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.
