Rules for Creating Remote Copy Virtual Volumes
•
The primary and secondary virtual volumes to be linked (for example, vv1 and vv1_remote)
must be the same size.
•
Volumes can have different RAID levels and availability levels (Cage, Magazine, and so on).
•
Volumes must be one of the following:
TPVVs ◦
◦ Fully provisioned virtual volumes
•
You can save read/write (RW) snapshots to Remote Copy volume groups.
For more information, see “Rules for Adding Snapshots to Volume Groups” (page 191) .
•
If you configure a TPVV as a primary virtual volume in a Remote Copy volume group, the
secondary volume should either:
◦ Have no data written to it before you add it to the Remote Copy volume group, or
◦ Match the primary volume exactly so the primary and secondary volumes match during
initial synchronization
