Resynchronization fails due to shortage of host resources
If a shortage of resources occurs in the host system, resynchronization of the Continuous Access
Synchronous Z pair may fail with host system messages: IOSHM0803E (HyperSwap Disabled)
and IOSHM0201I (Reason Code:40). In this case, correct the shortage of host resources by ensure
adequate resources. Do this first, then delete the failed Cnt Ac-S Z pair from TPC-R, and then
perform the pair create operation again.
Cache failure, unregistered TPC-R error
Both the pair create and pair resynchronization operations can fail if a cache failure occurs on
the storage system. You may receive an error code unregistered in TPC-R error messages, 0F0E,
in either of these instances.
In both cases, it is important to recover the cache failure first, then run the pair operation again.
NOTE: If you resynchronize before recovering from the cache failure, the resynchronization will
fail and TPC-R will delete the pair and then recreate the pair, copying the entire P-VOL to the S-VOL.
Pinned track recovery
This procedure ensures the pair’s full data integrity while recovering the pinned track.
Procedure 37 To recover a pinned track
1. Connect to the primary system of the pair containing a volume with the pinned track and select
the CU where the P-VOL is located.
2. Release the pair that contains the volume with the pinned track.
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 representative for assistance in recovering
the pinned track.
4. Recreate the pair. Make sure to use the Entire Copy in the Initial Copy Type option.
