Appendix C.1 RDAREA status transitions

The table below and Table C-2 RDAREA status transitions (2/2) show 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
Open#1 -- pdhold Transaction termination#3 pdhold -c pdhold -i N
Shutdown pdrels or pdrels -o -- N pdclose pdhold -i N
Closed pdopen, pdrels -o, or transaction startup#2 N -- pdhold or pdhold -c N pdhold -i
Shutdown and closed pdrels -o pdopen pdrels -- N pdhold -i
Ref-possible shutdown pdrels or pdrels -o N N N -- pdclose or transaction termination#3
Ref-possible shutdown and closed N N pdrels pdhold or pdhold -c pdopen or transaction startup#2 --
Ref-possible backup-hold pdrels or pdrels -o N N N N N
Ref-possible backup-hold and closed pdrels -o N pdrels N N N
Updatable backup-hold pdrels or pdrels -o N N N N N
Updatable backup-hold and closed pdrels -o N pdrels N N N

Legend:
--: Not applicable
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.
