Solution Problem
Ensure links are up on both systems and try the command
again. For more information, see
“Checking the Links
between Systems” (page 70) .
If the mirror system does not respond to a command after
5 minutes (the timeout limit), an error message appears:
target system could not be
contacted
Converting Standard Virtual Volumes
1. Ensure the virtual volume you want to use with Remote Copy does not share snapshot admin
or snapshot data space with any other virtual volume.
If the virtual volume shares these resources with other volumes, the conversion will fail.
2. Convert the standard virtual volume to a fully provisioned virtual volume and assign it to a
Common Provisioning Group (CPG).
# setvv -snp_cpg
•
- Name of the Common Provisioning Group to assign to the virtual volume
and from which snapshot space is to be allocated
•
- Name of the virtual volume to convert into a fully provisioned virtual volume
for use with Remote Copy
Growing Virtual Volumes
1. Stop the primary volume group that contains the virtual volume you want to grow.
# stoprcopygroup
•
- The volume group to stop
or:
# stoprcopygroup -pat
•
- Pattern of volume group names to stop (for example, Group*)
2. Increase the size of the virtual volume.
# growvv [g|G|t|T]
