volinfo(8)
NAME
volinfo - Print accessibility and usability of volumes
SYNOPSIS
/usr/sbin/volinfo [-Vp] [-g diskgroup] [-U usetype] [-o useopt] [volume...]
OPTIONS
The following options are recognized:
-V Writes a list of utilities that would be called from volinfo, along
with the arguments that would be passed. The -V performs a ``mock run''
so the utilities are not actually called.
-p Reports the name and condition of each plex in each reported volume.
-U usetype
Specifies the usage type for the operation. If no volume operands are
specified, the output is restricted to volumes with this usage type. If
volume operands are specified, this will result in a failure message
for all named volumes that do not have the indicated usage type.
-g diskgroup
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 operands. If no volume operands are specified, the disk group
defaults to rootdg.
-o useopt
Passes in usage-type-specific options to the operation. This option is
currently unsupported.
DESCRIPTION
The volinfo utility reports a usage-type-dependent condition on one or more
volumes in a disk group. A report for each volume specified by the volume
operand is written to the standard output. If no volume operands are given,
a volume condition report is provided for each volume in the selected disk
group.
Each invocation can be applied to only one disk group at a time, due to
internal implementation constraints. Any volume operands will be used to
determine a default disk group, according to the standard disk group
selection rules described in volintro(8). A specific disk group can be
forced with -g diskgroup.
Output Format
Summary reports for each volume are printed in one-line output records.
Each volume output line consists of blank-separated fields for the volume
name, volume usage type, and volume condition. Each plex output line
consists of blank-separated fields for the plex name and the plex
condition.
The following example shows the volume summary:
# volinfo
bigvol fsgen Startable
vol2 fsgen Started
brokenvol gen Unstartable
The following example shows the plex summary, with the plex records
accompanied by their volume records:
# volinfo -p
vol bigvol fsgen Startable
plex bigvol-01 ACTIVE
vol vol2 fsgen Started
plex vol2-01 ACTIVE
vol brokenvol gen Unstartable
Volume Conditions
The volume condition is a usage-type-dependent summary of the state of a
volume. This condition is derived from the volume's kernel-enabled state
and the usage-type-dependent states of the volume's plexes.
Volume conditions for the fsgen and gen usage types are reported as
follows:
Startable
The volume is not enabled and at least one of the plexes has a reported
condition of ACTIVE or CLEAN. A volume startall operation would likely
succeed in starting a volume in this condition.
Unstartable
The volume is not enabled and fails to meet the criteria for being
Startable. A volume in this condition is not started and may be
configured incorrectly or prevented from automatic startup (with volume
startall) because of errors or other conditions.
Started
The volume is enabled and at least one of the associated plexes is
enabled in read-write mode (which is normal for enabled plexes in the
ACTIVE and EMTPY conditions). A volume in this condition has been
started and can be used.
Started Unusable
The volume is enabled, but the volume does not meet the criteria for
being Started. A volume in this condition has been started, but is
inaccessible because of errors that have occurred since the volume was
started, or because of administrative actions, such as voldg -k rmdisk.
Volume conditions for volumes of the raid5 usage type include the following
conditions used for the fsgen and gen usage types:
Startable, Unstartable, Started, Started Unusable
Additional volume conditions for raid5 volumes are:
Degraded
The RAID-5 plex of the volume is in degraded mode due to the
unavailability of a subdisk in that plex.
Staleprty
Some of the parity in the RAID-5 plex is stale and requires recovery.
Plex Conditions
The following plex conditions (reported with -p) are reported for the fsgen
and gen usage types:
NODAREC
No physical disk was found for one of the subdisks in the plex. This
implies either that the physical disk failed, making it unrecognizable,
or that the physical disk is no longer attached through a known access
path.
REMOVED
A physical disk used by one of the subdisks in the plex was removed
through administrative action with voldg -k rmdisk.
IOFAIL
The plex was detached from use as a result of an uncorrectable I/O
failure on one of the subdisks in the plex.
STALE
The plex does not contain valid data, either as a result of a disk
replacement affecting one of the subdisks in the plex, or as a result
of an administrative action on the plex such as volplex det.
CLEAN
The plex contains valid data and the volume was stopped cleanly.
ACTIVE
Either the volume is started and the plex is enabled, or the volume was
not stopped cleanly and the plex was valid when the volume was stopped.
OFFLINE
The plex was disabled using the volmend off operation.
EMPTY
The plex is part of a volume that has not yet been initialized.
TEMP
The plex is associated temporarily as part of a current operation, such
as volplex cp or volplex att. A system reboot or manual starting of a
volume will dissociate the plex.
TEMPRM
The plex was created for temporary use by a current operation. A
system reboot or manual starting of a volume will remove the plex.
TEMPRMSD
The plex and its subdisks were created for temporary use by a current
operation. A system reboot or manual starting of the volume will remove
the plex and all of its subdisks.
SNAPATT
The plex is being attached as part of a backup operation by the
volassist snapstart operation. When the attach is complete, the
condition will change to SNAPDONE. A system reboot or manual starting
of the volume will remove the plex and all of its subdisks.
SNAPDONE
A volassist snapstart operation completed the process of attaching the
plex. It is a candidate for selection by the volassist snapshot
operation. A system reboot or manual starting of the volume will remove
the plex and all of its subdisks.
SNAPTMP
The plex is being attached as part of a backup operation by the volplex
snapstart operation. When the attach is complete, the condition will
change to SNAPDIS. A system reboot or manual starting of the volume
will dissociate the plex.
SNAPDIS
A volassist snapstart operation completed the process of attaching the
plex. It is a candidate for selection by the volplex snapshot
operation. A system reboot or manual starting of the volume will
dissociate the plex.
Plexes of raid5 volumes can be either data plexes (that is, RAID-5 plexes)
or log plexes.
Plex conditions for RAID-5 plexes and log plexes include the following
conditions used for the fsgen and gen usage types:
NODAREC, REMOVED, IOFAIL, CLEAN, ACTIVE, OFFLINE
RAID-5 plexes can have these additional conditions:
DEGRADED
Due to subdisk failures, the plex is in degraded mode. This indicates a
loss of data redundancy in the RAID-5 volume and any further failures
could cause data loss.
STALEPRTY
The parity is not in sync with the data in the plex. This indicates a
loss of data redundancy in the RAID-5 volume and any further failures
could case data loss.
UNUSABLE
A double failure occurred within the plex. The plex is unusable due to
subdisk failures and/or stale parity.
Log plexes of RAID-5 volumes can have this additional condition:
BADLOG
The contents of the plex are not usable as logging data.
EXIT CODES
The volinfo utility exits with a nonzero status if the attempted operation
fails. A nonzero exit code is not a complete indicator of the problems
encountered, but rather denotes the first condition that prevented further
execution of the utility. See volintro(8) for a list of standard exit
codes.
