Appendix C.1 RDAREA status transitions

Tables C-1 and C-2 describe the RDAREA status transitions during execution of operation commands.

Table C-1 RDAREA status transitions (1/2)

RDAREA status (before transition) RDAREA status (after transition)
Open Shutdown Closed Shutdown and closed Reference-possible shutdown Reference-possible shutdown and closed
Open1 [Figure] pdhold Transaction termination3 pdhold -c pdhold -i N
Shutdown pdrels or pdrels -o [Figure] N pdclose pdhold -i N
Closed pdopen, pdrels -o, or transaction startup2 N [Figure] pdhold or pdhold -c N pdhold -i

N: Cannot be in this RDAREA status after the transition
Ref: Reference
Synchro: Synchronization

1 The pdclose command will result in an error because the RDAREA is not shut down.

2 This status changes if the RDAREA open timing is either DEFER or SCHEDULE.

3 This status changes if the RDAREA open timing is SCHEDULE.

1 The pdclose command will result in an error because the RDAREA is not shut down.

2 This status changes if the RDAREA open timing is either DEFER or SCHEDULE.

3 This status changes if the RDAREA open timing is SCHEDULE.

4 This status changes if the RDAREA is not in reference-possible backup hold (update WAIT mode).

5 This status changes if the RDAREA open timing is DEFER.
