Procedure
1. Enable failsafe mode for any DR group containing more than one replication pair.
2. Set synchronous write mode for any DR groups in this procedure.
3. If normalization is occurring to m em bers of the DR group to be moved, wait for the members to
normalize.
4. If an application requires that I/O be suspended before creation of a snapclone, suspend I/O
at this time.
5. Create a sna
pclone of each virtual disk on the intermediate array (Site 2 in Figure 14).
6. Set the DR gr
oup back to asynchronous, if applicable.
7. Set failsa
fe mod e back to Disabled for the DR group, if applicable.
8. If the appl
ication was suspended in step 4, restart the host application.
9. Present the snapclone(s) to the host on the intermediate site (site 2 in Figure 14).
10. Place the snapcloned virtual disks into a new DR group.
11. Wait for normalization to complete.
12. Unprese
nt the host from the snapcloned virtual disks in the DR group on the intermediate array
(Site 2 in Figure 14).
13. Remove the remaining snapcloned virtual disks from the DR group by d eleting the DR group. Leave
the remote virtual disks intact by not discarding them during the deletion.
14. Delete the remaining snapcloned virtual d isk s from the intermediate array (Site 2 in Figure 14).
Post procedure
1. InHPCommandViewEVA,ontheremotearray(Site3inFigure 14), change the write protection of
the mirrored snapcloned virtual disks to that of no write protection.
2. Rename the virtual disk to a useful name in the H P Command View EVA interface.
The virtual disks are now available on the remote array for any pu rpose.
