5. Power on the RCU(s). Make sure that they are fully operational and ready to resynchronize
operations before powering on the MCUs.
6. Power on the MCU(s), and make sure that they are ready to resynchronize operations. If you
split any pairs in step 3, you can also resynchronize (pairresync) those pairs now.
Pinned Track Recovery for XP Continuous Access Volumes
To ensure full data integrity of the pair while recovering the pinned track, use the following
procedure:
1. Connect to the MCU of the XP Continuous Access pair that contains the volume with the pinned
track, and select the correct CU.
2. Release the XP Continuous Access pair (pairsplit-S) that contains the volume with the pinned
track.
If you release the XP Continuous Access Asynchronous pair, release only the pair that contains
the volume with the pinned track. To release only the XP Continuous Access Asynchronous
pair that contains the volume with the pinned track, select LU for Asynchronous Parameters
and Delete Range.
3. Perform your usual procedure for recovering data from a pinned track. See the pinned track
recovery procedures for your OS, or contact your HP Technical Support service representative
for assistance in recovering the pinned track.
4. Restart the pair using the Paircreate dialog box, and make sure to use the Entire Volume initial
copy option.
Make sure to specify the pair for which the pinned track recovery operation was performed.
