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 (VEA 500 Series) Getting Started 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.
