2. Convert the standard virtual volume to an FPVV and assign it to a CPG by issuing the following
command:
# setvv -snp_cpg <snp_CPG> <VV_name>
where:
• <snp_CPG>—Name of the CPG to assign to the virtual volume and from which snapshot
space is to be allocated.
• <VV_name>—Name of the virtual volume to convert into an FPVV for use with remote
copy.
Growing Virtual Volumes
Follow these steps to grow a virtual volume:
1. Stop the primary volume group that contains the virtual volume you want to grow by issuing
either of the following commands:
# stoprcopygroup <group_name>
where <group_name> represents the volume group to stop.
or:
# stoprcopygroup -pat <pattern>
where <pattern> represents the pattern of volume group names to stop (for example,
Group*).
2. Increase the size of the virtual volume by issuing the following command:
# growvv <VV_name> <size>[g|G|t|T]
where:
• <VV_name>—Name of the virtual volume you are growing.
• <size>—Size (in multiples of 256 MB) to add to the virtual volume’s user space. If the
increase is in gigabytes or terabytes, specify g, G, t, or T, respectively.
3. Start the volume groups by issuing either of the following commands:
# startrcopygroup <group_name>
or:
# startrcopygroup -pat <pattern>
For more information about the policy variables that determine how to start volume groups,
see “About the Remote-Copy Commands” (page 261).
