vxevac - evacuate all volumes from a disk
SYNOPSIS
/etc/vx/bin/vxevac [-g diskgroup] [-k [-O operation-tag]] [-t tasktag]
medianame [new_medianame...]
/etc/vx/bin/vxevac [-g diskgroup] [-O operation-tag] [-t tasktag]
commit medianame
/etc/vx/bin/vxevac [-g diskgroup] [-O operation-tag] [-t tasktag]
rollback medianame
DESCRIPTION
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.
KEYWORDS
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 opera-
tion 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.
OPTIONS -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 opera-
tion tag.
-t tasktag
Specifies an administrative operation to perform by the numeric identifier tasktag. See the vxtask(1M) manual page for informa-
tion on Veritas Volume Manager tasks.

volrecover(8) System Manager's Manual volrecover(8)NAME
volrecover - Performs volume recovery operations
SYNOPSIS
/sbin/volrecover [-g diskgroup] [-sb] [-o options] [volume | medianame...]
OPTIONS
Options that can be specified to volrecover are: Starts disabled volumes that are selected by the operation. Volumes will be started
before any other recovery actions are taken. Volumes will be started with the -o delayrecover start option. This requests that any opera-
tions that can be delayed in starting a volume will be delayed. In other words, only those operations necessary to make a volume available
for use will occur. Other operations, such as mirror resynchronization, attaching of stale plexes and subdisks, and recovery of stale RAID5
parity will normally be delayed. Performs recovery operations in the background. With this option, volrecover will put itself in the back-
ground to attach stale plexes and subdisks, and to resynchronize mirrored volumes and RAID5 parity. If this is used with -s, volumes will
be started before recovery begins in the background. Performs no recovery operations. If used with -s, volumes will be started, but no
other actions will be taken. If used with -p, the only action of volrecover will be to print a list of startable volumes. Prints the list
of selected volumes that are startable. For each startable volume, a line is printed containing the following information: the volume name,
the disk group ID of the volume, the volume's usage type, and a list of state flags pertaining to mirrors of the volume.
State flags and their meanings are: One of the mirrors was detached by an I/O failure One of the mirrors needs recovery, but the
recovery is related to an administrative operation, not an I/O failure Neither kdetach nor stale is appropriate for the volume.
Displays information about each task started by volrecover. For recovery operations (as opposed to start operations), a completion
status is printed when each task completes. Displays commands that volrecover would execute without actually executing them. Lim-
its operation of the command to the given disk group, as specified by disk group ID or disk group name. If no volume or medianame
operands are given, all disks in this disk group will be recovered; otherwise, the volume and medianame operands will be evaluated
relative to the given disk group.
Without the -g option, if no operands are given, all volumes in all imported disk groups will be recovered; otherwise, the disk
group for each medianame operand will be determined based on name uniqueness within all disk groups. Passes the given option argu-
ments to the -o options for the volplex att and volume start operations generated by volrecover. An option argument of the form pre-
fix:options can be specified to restrict the set of commands that the -o option should be applied to.
Defined prefixes are: Applies to all invocations of the volume utility (volume starts, mirror resynchronizations, RAID5 partity
rebuilds, and RAID5 subdisk recoveries) Applies to all invocations of the volplex utility (currently used only for attaching plexes)
Applies specifically to plex attach operations applies specifically to volume start operations Applies to subdisk recoveries Applies
to mirror resynchronization and RAID5 parity recovery
DESCRIPTION
The volrecover program performs plex attach, RAID5 subdisk recovery, and resynchronize operations for the named volumes, or for volumes
residing on the named disks (medianame).
If no medianame or volume operands are specified, the operation applies to all volumes (or to all volumes in the specified disk group).
If -s is specified, disabled volumes will be started. With -s and -n, volumes are started, but no other recovery takes place.
Recovery operations will be started in an order that prevents two concurrent operations from involving the same disk. Operations that
involve unrelated disks will run in parallel.
EXAMPLES
To recover, in the background, any detached subdisks or plexes that resulted from replacement of a specified disk, use the command:
# volrecover -b medianame
If you want to monitor the operations, use the command:
# volrecover -v medianame
