NAMEvxrecover — perform volume recovery operations SYNOPSISvxrecover
[-bcEnpsvV]
[-g diskgroup ]
[-o options ]
[-t tasktag ]
[ volume | medianame...] DESCRIPTIONThe
vxrecover
utility performs plex attach, RAID-5 subdisk recovery,
and resynchronize operations for the named volumes,
or for volumes residing on the specified disks medianame.
If no
medianame
or
volume
is specified,
the operation applies to all volumes,
or to all volumes in the specified disk group.
If
-s
is specified,
disabled volumes are started.
With
-s
and
-n,
volumes are started, but no other recovery takes place. Recovery operations are started in an order that prevents two
concurrent operations on the same disk.
Operations that involve unrelated disks run in parallel. OPTIONS- -b
Performs recovery operations in the background.
With this option,
vxrecover
runs in the background to attach stale plexes and subdisks,
and to resynchronize mirrored volumes and RAID-5 parity.
If this is used with
-s,
volumes are started before
recovery begins in the background. - -c
Operates on cluster-shareable disk groups.
This option is used by the cluster reconfiguration utility
to effect recovery on volumes in shared disk groups
after the failure of a node in the cluster.
Do not use
-c
as a command-line option.
Available only if the Volume Manager cluster feature is enabled
and a license is installed. - -E
Starts disabled volumes or plexes even when they are in the EMPTY state.
This is useful for starting up volumes restored by the
vxmake
utility when specified along with the
-s
option. - -g diskgroup
Limits operation of the command to the given disk group,
as specified by disk group ID or disk group name.
If no
volume
or
medianame
is specified,
all disks in this disk group are recovered,
otherwise,
the
volume
and
medianame
are evaluated relative to the given disk group. Without the
-g
option,
if no
volume
and
medianame
is specified,
all volumes in all imported disk groups are recovered;
otherwise, the disk group for each medianame specified is
determined based on name uniqueness within all disk groups. - -n
Does not perform any recovery operations.
If used with
-s,
volumes are started,
but no other actions are taken.
If used with
-p,
vxrecover
only prints a list of startable volumes. - -o options
Passes the given option arguments to the
-o
options for the
vxplex att
and
vxvol start
operations generated by
vxrecover.
You can specify an option argument in the form
to restrict the set of commands that the
-o
option is applied to.
Defined prefixes are:
vol applies to all invocations of the vxvol
utility (volume starts, mirror resynchronizations, RAID-5 partity
rebuilds, and RAID-5 subdisk recoveries) plex, applies to all
invocations of the vxplex utility (used only for
attaching plexes) attach applies specifically to plex attach
operations start applies specifically to volume start
operations recover applies to subdisk recoveries resync applies to mirror resynchronization and RAID-5 parity
recovery.
- -p
Prints the list of selected volumes that are startable.
For each startable volume,
a line is printed containing 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 include:
kdetach
indicates that one of the mirrors was detached by an I/O failure stale
means that one of the mirrors needs recovery,
but that the recovery is related to an administrative operation,
not an I/O failure stopped
prints if neither
kdetach
nor
stale
is appropriate for the volume.
- -s
Starts disabled volumes that are selected by the operation.
Volumes are started before any other recovery actions are taken.
Volumes are started with the
-o delayrecover
start option.
This requests that any operations that can be delayed in starting a volume
are delayed.
That is,
only those operations necessary to make a volume available for use occur.
Other operations,
such as mirror resynchronization,
attaching of stale plexes and subdisks,
and recovery of stale RAID-5 parity,
are typically delayed. - -t tasktag
If any tasks are registered to track the progress of the operation,
marks them with the tag
tasktag.
This option is also passed to
any utilities called to perform recoveries,
so all tasks registered by
any utility to perform the recoveries are also tagged with
tasktag. - -v
Displays information about each task started by
vxrecover.
For recovery operations (as opposed to start operations),
prints a completion status when each task completes. - -V
Displays each command executed by
vxrecover.
The ouput generated is more verbose than the job descriptions
printed with the
-v
option.
EXAMPLESTo recover, in the background, any detached subdisks or plexes that
resulted from replacement of a specified disk, use the command:
To monitor the operations, use the command:
