volinfo - Print accessibility and usability of volumes
/usr/sbin/volinfo [-g diskgroup] [-U usetype] [-o useopt] [volume...]
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, then 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
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
The following options are recognized:

to volumes with this usage type. If
are specified, then this will result in a failure message for all named volumes
that do not have the indicated usage type.
Specify 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
operands. If no

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.
utility reports the following conditions
operation would likely
succeed in starting the volume.
The volume is not started and either is not correctly configured
or doesn't meet the prerequisites for automatic startup (with
startup) because of errors or other conditions.
The volume has been started and can be used.
The volume has been started but is not operationally accessible.
This condition may result from errors that have occurred since the volume
was started, or may be a result of administrative actions, such as
voldg -k rmdisk.
Summary reports for each volume are printed in one-line output records. The volume output line consists of blank-separated fields for the volume name, volume condition, and the type of the volume. The following example shows the volume summary:
bigvol fsgen Startable vol2 fsgen Startable brokenvol gen Unstartable
The output format for each plex is a one-line output record consisting of blank-separated fields for the plex name and the plex condition, as a usage-type-dependent string. The plex records are indented from the volume records, as the following example shows:
vol bigvol fsgen Startable plex bigvol-01 ACTIVE vol vol2 fsgen Startable plex vol2-01 ACTIVE vol brokenvol gen Unstartable
The fsgen and gen usage types provide identical semantics for the volinfo utility. The fsgen and gen usage types do not support any options passed in with -o.
Plex conditions (reported with -p) can be one of the following: 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. A physical disk used by one of the subdisks in the plex was removed through administrative action with voldg -k rmdisk. The plex was detached from use as a result of an uncorrectable I/O failure on one of the subdisks in the plex. 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. The plex contains valid data and the volume was stopped cleanly. 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. The plex was disabled using the volmend off operation. The plex is part of a volume that has not yet been initialized. 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. The plex was created for temporary use by a current operation. A system reboot or manual starting of a volume will remove the plex. 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. 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. 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. 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. 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.
