The
vxevac
utility moves subdisks off the specified Veritas Volume Manager (VxVM) disk
(medianame)
to the specified destination disks
(new_medianame...).
If no
new_medianame
arguments are specified,
any non-volatile,
non-reserved disks can be used as destination disks.
Subdisks that are part of unmirrored striped plexes
are moved by moving the entire plex to a new location.
Note: This operation assumes that there is sufficient space in
the disk group for the operation to complete.
If the process runs out of space,
some of the volumes on the disk may not be evacuated.
vxevac
is usually called from the
vxdiskadm
menus.
A
medianame
argument is an administrative name used
to define a disk within a disk group.
The evacuation of a volume can be committed or rolled back if the -k
option is specified. Such an operation is referred to as a "tentaive move."
In addition, the -O option may be used to define a tag for a
given tentative move operation.
-
commit
-
Completes tentative subdisk move operations by removing the
source subdisks, and replacing them with the target subdisks.
The -O option can be used to specify an operation tag for the
subdisks whose tentative move is to be committed.
If no operation tag is specified, the commit operation is applied
to all completed tentative subdisk moves for the specified media.
The commit operation fails if a tentative move or
a recovery resynchronization is in progress.
-
rollback
-
Reverses tentative subdisk move operations by removing the
target subdisks, and leaving the source subdisks intact.
The -O option can be used to specify an operation tag for the
subdisks whose tentative move is to be rolled back.
If no operation tag is specified, the rollback operation is applied
to all completed tentative subdisk moves for the specified media.
The rollback operation fails if a tentative move or
a recovery resynchronization is in progress.
-
-g diskgroup
-
Specifies the disk group for the operation,
either by disk group ID or by disk group name.
-
-k
-
Initiates a subdisk move while preserving the source subdisks on the
original plexes. The source and target subdisks are marked.
The tentative move operation can be committed or rolled back at a later time.
If the -O option is used to specify a tag, this tag can be used with
the vxtask command to monitor, pause or abort such operations.
-
-O operation-tag
-
Specifies an operation tag that can be used to commit or roll back a
completed tentative move operation.
If an operation tag is specified, a task tag is automatically set to the
same value. However, setting a task tag does not imply the setting of an
operation tag.
-
-t tasktag
-
Specifies an administrative operation to perform by the numeric identifier
tasktag.
