You can use SnapDrive for UNIX to carry out thin provisioning on your storage system. Thin provisioning is also referred as space-reservation.
Step
- Set the space-reservations-enabled configuration variable value to on.
You can also enable thin provisioning by using the
-reserve and
-noreserve parameters.
Parameter override the value mentioned in the -space-reservations-enabled variable.
You could use
-reserve and
-noreserve with the following commands to enable or disable LUN reservation:
- snapdrive storage create
- snapdrive storage resize
- snapdrive snap connect
- snapdrive snap restore
By default, SnapDrive for UNIX enables space reservation for a fresh or new storage create operations. For snap restore and snap connect operations, it uses the space reservation present in the Snapshot copy if the -reserve or -noreserve parameters are not specified at the command line, or if the value in the configuration file is uncommented.
