3. Click Start d eletion process.
After a prompt for confirmation, a list of failed DR groups is displayed.
4. One at a time, select the affected DR groups and click Delete. Deleting a DR group removes the
relationship between the virtual disk members. It does not delete data from the virtual disks.
5. Select an

to cr eate disk groups, see EVA and HP Command View EVA user guides.
9. Refresh the new source array, and re-create the DR groups.
10. On the repaired array (new destination), present the destination virtual disks.
11. After n
ormalization occurs between the source and destination arrays, fail over the DR groups on the
desti
nation a rray, using the procedure described in Planned failover.
If dat
a is logging when a source disk group hardware failure occurs, the data on the destination array is
stale
(not current). You have the following options:
• Recover using the stale data on the destination array (see Disk group hardware failure on the
source array).
• Reco
ver from a known, good point using a b ackup.
• If you want to perform a failover to activate the destination array before repairing the inoperative
disk group, use the procedure on Disk group hardware failure on the source array.
• If you want to repair the inoperative disk g roup first, perform the repair, delete the inoperative DR
groups and virtual disks on the failed system, re-create virtual disks and DR groups, and then
restore your data from an external backup.
