Action D:

A PPRC path exists from the primary to the secondary, but not in the reverse direction. The primary and secondary volumes do not have the same physical capacity. P/DAS takes no special action to use the additional capacity on the target volume. 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. If you reply with "2" (Try Again), P/DAS issues the following message, which requires an operator reply:
IGF522A UNABLE TO SWITCH, FROM DEVICE IS SMALLER THAN TO DEVICE:
   REPLY 1 TO CONTINUE SWAP │ 2 TO TERMINATE SWAP

Select one of the message options, as described in Table 1.
