Description
|
vxassist [-g diskgroup] mirror volume \ [attributes]
|
Adds a mirror to a volume. See Adding a Mirror to a Volume.
Example:
# vxassist -g mydg mirror myvol \ mydg10
|
vxassist [-g diskgroup] remove mirror \ volume [attributes]
|
Removes a mirror from a volume. See Removing a Mirror.
Example:
# vxassist -g mydg remove \ mirror myvol !mydg11
|
vxassist [-g diskgroup] {growto|growby}\ volume length
|
Grows a volume to a specified size or by a specified amount. See Resizing Volumes using vxassist.
Example:
# vxassist -g mydg growby myvol \ 10g
|
vxassist [-g diskgroup] \
{shrinkto|shrinkby} volume length
|
Shrinks a volume to a specified size or by a specified amount. See Resizing Volumes using vxassist.
Example:
# vxassist -g mydg shrinkto myvol \ 20g
|
vxresize -b -F xvfs [-g diskgroup] \ volume length diskname ...
|
Resizes a volume and the underlying VERITAS File System. See Resizing Volumes using vxresize.
Example:
# vxassist -b -F vxfs -g mydg \ myvol 20g mydg10 mydg11
|
vxsnap [-g diskgroup] prepare volume \
[drl=on|sequential|off]
|
Prepares a volume for instant snapshots and for DRL logging. See Preparing a Volume for DRL and Instant Snapshots.
Example:
# vxsnap -g mydg prepare myvol \ drl=on
|
vxsnap [-g diskgroup] make \ source=volume/newvol=snapvol\ [/nmirror=number]
|
Takes a full-sized instant snapshot of a volume by breaking off plexes of the original volume. See Creating Instant Snapshots.
Example:
# vxsnap -g mydg make \ source=myvol/newvol=mysnpvol\ /nmiror=2
|
vxsnap [-g diskgroup] make \ source=volume/snapvol=snapvol
|
Takes a full-sized instant snapshot of a volume using a prepared empty volume. See Creating a Volume for Use as a Full-Sized Instant Snapshot and Creating Instant Snapshots.
Example:
# vxsnap -g mydg make \ source=myvol/snapvol=snpvol
|
vxmake [-g diskgroup] cache \ cache_object cachevolname=volume \ [regionsize=size]
|
Creates a cache object for use by space-optimized instant snapshots. See Creating a Shared Cache Object. A cache volume must have already been created, as shown in this example:
# vxassist -g mydg make cvol 1g \ layout=mirror init=active \ mydg16 mydg17
# vxmake -g mydg cache cobj \ cachevolname=cvol
|
vxsnap [-g diskgroup] make \ source=volume/newvol=snapvol\ /cache=cache_object
|
Takes a space-optimized instant snapshot of a volume. See Creating Instant Snapshots.
Example:
# vxsnap -g mydg make \ source=myvol/newvol=mysosvol\ /cache=cobj
|
vxsnap [-g diskgroup] refresh snapshot
|
Refreshes a snapshot from its original volume. See Refreshing an Instant Snapshot (vxsnap refresh).
Example:
# vxsnap -g mydg refresh mysnpvol
|
vxsnap [-g diskgroup] dis snapshot
|
Turns a snapshot into an independent volume. See Dissociating an Instant Snapshot (vxsnap dis).
Example:
# vxsnap -g mydg dis mysnpvol
|
vxsnap [-g diskgroup] unprepare volume
|
Removes support for instant snapshots and DRL logging from a volume. See Removing Support for DRL and Instant Snapshots from a Volume.
Example:
# vxsnap -g mydg unprepare myvol
|
vxassist [-g diskgroup] relayout volume \ [layout=layout] [relayout_options]
|
Performs online relayout of a volume. See Performing Online Relayout.
Example:
# vxassist -g mydg relayout \ vol2 layout=stripe
|
vxassist [-g diskgroup] relayout volume \ layout=raid5 stripeunit=W ncol=N
|
Relays out a volume as a RAID-5 volume with stripe width W and N columns. See Performing Online Relayout.
Example:
# vxassist -g mydg relayout \ vol3 layout=raid5 \ stripeunit=16 ncol=4
|
vxrelayout [-g diskgroup] -o bg reverse \ volume
|
Reverses the direction of a paused volume relayout. See Controlling the Progress of a Relayout.
Example:
# vxrelayout -g mydg -o bg \ reverse vol3
|
vxassist [-g diskgroup] convert volume \ [layout=layout] [convert_options]
|
Converts between a layered volume and a non-layered volume layout. See Converting Between Layered and Non-Layered Volumes.
Example:
# vxassist -g mydg convert vol3 \ layout=stripe-mirror
|
vxassist [-g diskgroup] remove volume \ volume
|
Removes a volume. See Removing a Volume.
Example:
# vxassist -g mydg remove myvol
