46 Understanding ISP
Examples of using ISP from the command line
See “Creating application volumes” on page 61.
See “Creating instant snapshots” on page 101.
Resizing an application volume
If the application volume, stmrvol, that you have just created is not large
enough for your needs, you can increase its size using this command:
# vxassist -g mydg -p mypool growto stmrvol 4g
Any file system or other application storage layout that you have created on the
volume can be resized after you have grown the volume.
See “Resizing volumes online” on page 76.
Creating a clone storage pool
Assuming that you also want to create full-sized snapshots of application
volumes in mypool that can be moved into a different disk group, the following
command creates a clone storage pool, myclpool, in the same disk group as
mypool:
# vxpool -g mydg create myclpool \
dm=mydg09,mydg10,mydg11,mydg12 \
autogrow=pool pooldefinition=mirrored_volumes
This pool supports the creation of mirrored volumes. It also has a non-default
autogrow policy that prevents it aggregating disks from the disk group outside
the pool.
See “Preparing storage pools for full-sized instant snapshots” on page 95.
Preparing a full-sized snapshot volume
Before you can take a full-sized snapshot of an application volume, you must
prepare the empty volume that is to become the snapshot volume as shown here:
# vxassist -g mydg -P myclpool make mysnpvol 2g type=snapshot\
init=active
This command automatically associates a data change object (DCO) and DCO
volume with the volume.
See “Creating a volume for use as a full-sized instant or linked break-off
snapshot” on page 96.
