TrueCopy pairs in the reverse direction using the None initial copy
option. If the original P-VOLs will be temporarily unavailable for
update copy operations, you can split the new pairs (pairsplit-r) so
that the new primary system keeps track of changes.

If the original P-VOL is temporarily unavailable for update copy operations,
split the new pair so that the new primary system keeps track of changes.
