Displaying Disk Information

Before you use a disk, you need to know if it has been initialized and placed under VxVM

control.You alsoneed to knowif the diskis part ofa disk groupbecause youcannotcreate

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 disksthat are known toVxVM, usethe 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 thatare listedas online are already under VxVM control.

To display details on a particular disk deﬁned to VxVM, use the following command:

# vxdisk list diskname
