S-VOL access P-VOL access Host status Description Status
Read/write-disabled Read/write-enabled S-VOL = PPRI-PNDG The pair is suspended by the storage system.

to the P-VOL. Update copy operations are
stopped to the S-VOL. The system marks the
entire P-VOL track map as differential data,
meaning that the entire P-VOL is copied to
the S-VOL when the suspended pair is
resynchronized.
* Starting time of the copy depends on the numbers of pairs and the system environment.
CAUTION: When you execute DEVSERVE to a read/write disabled volume, INTERVENTION
REQUIRED is returned. However, if you have created pairs with the volumes online, and then
execute DEVSERVE to a read/write disabled volume, a normal value is returned.
