1. With BCM, the command terminates normally but pair status does not change because resync processing is not performed.
2. If you use the PPRC TSO command, the command terminates normally but pair status does not change because resync
processing is not performed. However, if you specify YES in the MSGREQ parameter, the command terminates abnormally
with CC=8.
If you use the ICKDSF PPRCOPY command, the command terminates abnormally with CC = 12.
3. If the pair status changes from Suspend/SUSPER to Resync/PENDING, the PPRC TSO command ends abnormally with CC=8.

Status of unaffected S-VOLs, operations permitted
The pair operations you can perform depend on the pair’s status, but also on the status of unaffected
S-VOLs. The following table shows which operations can be performed, given the status of S-VOLs
related to the P-VOL in other pairs.
