7. Reconfigure scripts for failover on the application servers.

Setting up a new production site

Setting up a new production site involves creating a new primary volume and synchronizing the acting
primary volume before returning it to its original state as a remote volume. The steps are the same as
those for creating a new primary volume at the original production site.

Making the backup site into the new production site

Turn the backup site into the new production site and designate a different backup site. The steps are
similar to those for initially configuring Remote Copy.
1. Create a remote snapshot or a timetable for a scheduled remote snapshot on the acting primary
volume.
2. Make a new remote volume on the new backup site as part of creating that remote snapshot or
timetable for a scheduled remote snapshot.
3. Reconfigure scripts for failover on the application servers.

Rolling back primary and remote volumes

Rolling back a volume from a snapshot is one method for reverting to an earlier copy of the data on
a volume. Rolling back procedures requires that you delete any snapshots that were created after the
snapshot that is rolled back to.

Using SmartClone to clone a volume from a snapshot

Consider using the SmartClone feature to clone a volume from a snapshot that contains the earlier
copy of the data you want to use. Creating a SmartClone volume preserves all snapshots while
providing an exact copy of the desired data. The SmartClone volume consumes no extra space on
the SAN.

Rolling back a primary volume

Rolling back a primary volume to a snapshot replaces the original volume with a volume that contains
the snapshot's data. The new volume has the same name as the original.
If a volume is part of a volume set, typically you want to roll back each volume using its corresponding
snapshot. The system allows you to automatically roll back all associated volumes. To see any
associated snapshots, select a snapshot, click the Details tab, and then look at the Snapshot Set field.
For more information about volume sets and snapshot sets, see the HP StorageWorks P4000 SAN
Solution user guide or online help.

Prerequisites

Stop applications from accessing the volume.
CAUTION:
Any remote snapshot that has not completed copying is canceled.
