HP 3PAR Remote Copy Software - Manual (Page 83)

3.21 Setting Up Remote Copy
InForm OS Version 2.3.1 Remote Copy User’s Guide
returns a Status of Up, the links have come up. Be sure to check that links are up on both
systems (the previous example shows output for InServ2 only).
After all links come up between the Remote Copy pair, you can proceed with creating
volume groups on the systems.
3.5.1.3 Creating Remote Copy Volume Groups
Before creating volume groups, you must create volumes on each storage server separately
through the normal volume creation commands. The volumes must be the same size, though
they can have different RAID levels and availability levels (e.g., Cage versus Magazine). In
addition, they must be TPVVs or fully provisioned virtual volumes. See the 3PAR InForm OS CLI
Administrator’s Manual for instructions on creating volumes.
Follow these steps to create the Remote Copy volume groups on the primary and backup
storage servers.
1 Set up a volume group on the primary storage server as follows:
In order to use this command, you must specify a (for example, Group1),
the (for example, InServ2) and a mode ( sync for synchronous or
periodic for asynchronous periodic).
NOTE: If there are any problems with the way that the links were created, use the
dismissrcopylink : command to
remove links and then try again.
NOTE: When a TPVV is configured as a primary volume in a Remote Copy group,
the secondary volume should have no data written to it prior to adding it the
Remote Copy group, or it must match the primary volume in order for the primary
and secondary volumes to match during initial synchronization.
On InServ1:
