Starting a Volume
Starting a volume affects its availability to the user. Starting a volume
changes its state, makes it available for use, and changes the volume
state from DISABLED or DETACHED to ENABLED. The success of this
task depends on the ability to enable a volume. If a volume cannot be
enabled, it remains in its current state. To start a volume, use the
following command:
# vxrecover -s volume_name ...
To start all DISABLED volumes, use the following command:
# vxrecover -s
If all mirrors of the volume become STALE, you can place the volume in
maintenance mode. Then you can view the plexes while the volume is
DETACHED and determine which plex to use for reviving the others. To
place a volume in maintenance mode, use the following command:
# vxvol maint volume_name
To assist in choosing the revival source plex, list the unstarted volume
and display its plexes. For example, to take plex vol01-02 offline, use
the following command:
# vxmend off vol01-02
The vxmend command can change the state of an OFFLINE plex of a
DISABLED volume to STALE.Avxvol start command on the volume then
revives the plex. For example, to put a plex named vol01-02 in the
STALE state, use the following command:
# vxmend on vol01-02
Listing Unstartable Volumes
An unstartable volume can be incorrectly configured or have other errors
or conditions that prevent it from being started. To display unstartable
volumes, use the vxinfo command. The vxinfo command displays
information on the accessibility and usability of one or more volumes:
# vxinfo [ volume_name ]
