volrecover - Performs volume recovery operations
/sbin/volrecover [-g diskgroup] [-sb] [-npVv] [-o options]
[volume | medianame...]
Specifies the disk group for the operation, either by disk
group ID or by disk group name. By default, the disk group
is chosen based on the volume or medianame operands. If no
volume or medianame operands are given, all disks in this
disk group will be recovered.
Without the -g option and operands, all volumes
needing recovery in all imported disk groups will
be recovered. Starts disabled volumes selected by
the operation. LSM starts the selected volumes with
the -o delayrecover start option before performing
any other recovery actions. This requests that any
operations 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,
attachment of stale plexes and subdisks,
and recovery of stale RAID 5 parity are normally
delayed. Performs recovery operations in the
background. With this option, volrecover will run
in the background to attach stale plexes and subdisks
and to resynchronize mirrored volumes and
RAID 5 parity. If the -b option is used with the -s
option, volumes will be started before recovery
begins. Performs no recovery operations. If used
with the -s option, volumes are started, but no
other actions are taken. If the -n option is used
with the -p option, volrecover prints a list of
startable volumes. Prints a list of selected volumes
that are startable. The list contains 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. Performs a "mock run" of the command. Displays
the commands that volrecover would execute if
the operation actually executed. Runs in verbose
mode; displays information about each task started
by volrecover. For recovery operations (as opposed
to start operations), a completion status is displayed
when each task completes. Passes the given
option arguments to the -o options for the volplex
att and volume start operations invoked by volrecover.
An option argument of the form prefix:options
can be specified to restrict the set of
commands that the -o option should be applied to.
See volume(8) and volplex(8) for the options you
can use with prefix.
Defined prefixes are: Applies to all invocations of
the volume utility (volume starts, mirror resynchronizations,
RAID 5 parity rebuilds, and RAID 5
subdisk recoveries) Applies to all invocations of
the volplex utility (used only for attaching
plexes) Applies specifically to plex attach operations
Applies specifically to volume start operations
Applies to volume resynchronizations. Starts
the volume in degraded mode; defers resynchronization
until you initiate it manually. Applies to
subdisk recoveries Applies to mirror resynchronization
and RAID 5 parity recovery
Specifies the volume to recover. Limits recovery to the
specified volume. Specifies the disk to recover. Recovers
all LSM objects on the named disk.
The volrecover utility performs plex attach, RAID 5 subdisk
recovery, and resynchronization operations for the
named volumes or for volumes that use the named disks
(medianame).
If no medianame or volume operands are specified, the
operation applies to all volumes requiring recovery (or to
all such volumes in the specified disk group).
If the -s option is specified, disabled volumes will be
started. With the -s and -n options, volumes are started,
but no other recovery takes place.
Recovery operations are started in an order that prevents
two concurrent operations from involving the same disk.
Operations that involve unrelated disks will run in parallel.
To recover in the background any detached subdisks or
plexes that resulted from replacement of a specified disk,
enter:
# volrecover -b medianame To monitor the operations,
use the command:
# volrecover -v medianame
Commands: volplex(8), volume(8)
Other: volintro(8)
