A PPRC path exists from the primary to the secondary, but not in
the reverse direction. The primary and secondary volumes have the
same physical capacity. In this situation, your
"switch pair, and
swap" choice directs P/DAS to issue the following additional message
to the system operator:
IGF521A NO PATH IN OPPOSITE DIRECTION: REPLY 1 TO CONTINUE SWAP │
2 TRY AGAIN │ 3 TERMINATE SWAP
Select one of the message options, as described in Table 1.
