Managing the HOLDTRNS Status
If the pair status changes to HOLDTRNS before execution of the command YKRESYNC DELTAJNL
(delta resync pair synchronization), or if the pair status does not change from HOLDTRNS to HOLD
after execution of the command YKMAKE HOLD (delta resync pair creation), no differential update
has been kept in journal between the local site and the remote site because of an environmental
reason or the effect of the copy pair status of other copy group. In this case, perform the following
procedure to change the copy pair status to HOLD:
1. Check Table 108 (page 446) to see if all conditions are met. If any of the conditions is not met,
perform the action shown in Action Item.

Cnt Ac-S Z pairs. Make sure that the All Cnt Ac-S Z pairs have the same
copy direction.
copy direction of all Cnt Ac-S Z
pairs is set from the primary site
toward the local site, or from the
