# pairsplit -g dg12
b. Resync the device group dg12
# pairresync -g dg12
c. Wait for PAIR state to come up.
# pairevtwait -g dg12 -t 300 -s pair
• If in step 1, the dg12 pair was not split to SMPL and the dg12 local volume is SVOL-SSWS
# pairresync -g dg12 -c 15 -swaps
a. Wait for PAIR state to come up
# pairevtwait -g dg12 -t 300 -s pair

TRI-LINK Data Recovery from DC3 to DC1
The following describes the process to recover the latest data at DC1 after the package fails over
to DC3 where Delta Resync pair is configured between DC1 or DC2, and DC3:
1. Delete all the three device group pairs configured for the package.
a. Split all the device group pairs into SMPL state using the pairsplit command. If you are
not able to delete the pairs using the RAID Manager Commands, delete the device group
pair using the XP Remote Web Console. For more information on P9000 or XP Remote
Web Console, see HP StorageWorks XP24000/XP20000 Remote Web Console User
Guide document available at: http://h20000.www2.hp.com/bc/docs/support/
SupportManual/c02254250/c02254250.pdf.
b. Ensure that all device group pairs are in SMPL state.
