 <VV_name> is the name of the volume being created. The name can be up to 31

when the volumes’ capacity has been reached.
X To grow a TPVV, issue the growvv <size> <TPVV_name> command, where:
 <size> is the grow size of the volume’s user space in MB, specified as an integer from
1 to 2096128 (you can also specify the size in gigabytes by following the integer with g
or G).
 <TPVV_name> is the name of the TPVV you are growing.
7.11.3 Modifying a Thinly Provisioned Virtual Volume
Any existing TPVV can be modified to have a new name, new allocation limits and warnings, or
to adhere to specific policies.
X To modify an existing TPVV, issue the setvv command. Refer to the InForm OS Command
Line Interface Reference for details on all arguments and their usage, which are available
for the
setvv command.
