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 VxVM GUI
(Storage Administrator), or the command line interface. For more
information, refer to the VERITAS Volume Manager 3.1 Storage
Administrator Administrator’s Guide and the VERITAS Volume
Manager 3.1 Administrator’s Guide.
Table 3-3Additional 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
havebeen 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
