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
