Figure 49 Business Copy cascade volume pairs

Restrictions for Business Copy cascading volumes

Pair Creation. Pair creation of S-VOL (oradb1) can only be performed after the pair creation of

S/P-VOL (oradb). If you create the oradb1 pair first without creating the oradb, the subsequent

oradb creation will be rejected with EX_CMDRJE or EX_CMDIOE.

Pair splitting. Pair splitting of S-VOL (oradb1) can only be performed after the S/P-VOL (oradb) is

in a SMPL or PSUS state, since Business Copy copies are asynchronous. If pair splitting of the

S-VOL (oradb1) is attempted while the S/P-VOL (oradb) is in a COPY or PAIR state, the pairsplit

command is rejected with EX_CMDRJE or EX_CMDIOE.

Pair restore. Pair restore (resync from S-VOL (oradb1) to S/P-VOL) can only be performed when

the S-VOL (oradb) and the P-VOL (oradb2) on the S/P-VOL are in a SMPL state. If the pair restore

of S-VOL (oradb1) is performed while either the S-VOL (oradb) or P-VOL (oradb2) on the S/P-VOL

are in a COPY, PAIR or PSUS state, the pairresync -restore command is rejected with EX_CMDRJE

or EX_CMDIOE.
