Tasks with no direct LVM equivalents

The following table lists tasks which have no direct LVM equivalent. Most of

these tasks can be performed either with the Veritas Enterprise Administrator

(VEA) GUI, or the command line interface. For more information, refer to the

Veritas Enterprise Administrator User’s Guide and the Veritas Volume Manager

Administrator’s Guide.

Table 3-3 Additional VxVM tasks with no LVM equivalents

Task description Example

Hot-relocation: in addition to using disks as hot

spares, the hot relocation facility can also use any

available free space in the disk group. If no disks

have been designated as spares when a failure of a

redundant object occurs, VxVM automatically uses

any available free space in the disk group in which

the failure occurs. If there is not enough spare disk

space, a combination of spare space and free space

is used. After a disk is repaired, you can move all the

hot-relocated subdisks back to the original disk

using the vxunreloc (1M) utility.

No action needed for hot relocation.

To move hot-relocated subdisks back to the original

disk:

vxunreloc disk_name

Rename a disk vxedit rename old_diskname new_diskname

Offline a disk. vxdisk offline disk_name

Alternatively, menu option 12 of vxdiskadm performs

this task.

Online a disk. vxdisk online disk_name

Select menu option 10 of vxdiskadm.

Evacuate a disk. vxevac -g disk_group medianame

new_medianame

Replace a disk. Select menu option 4 of vxdiskadm.

Recover volumes on a disk. vxrecover -g disk_group vol_name medianame

Display a DMP node. vxdisk list meta_device

Rename a disk group. vxdg -tC -n newdg_name

Rename a volume. vxedit -v rename name

newname

Update the /usr/fstab file with the new name.

Add a DRL log to a volume. vxassist addlog vol_name

Create a snapshot copy of a volume. vxassist snapshot vol_name temp_vol_name
