Description
The user has split the pair or released the pair; the pair is no
longer synchronized.
The primary and secondary systems keep track of journal data
discarded during the pairsplit operation.
When the operation is performed at the primary system, the
status of both the P-VOL and S-VOL change to PSUS.
When the operation is performed at the secondary system,
the status of the S-VOL changes to PSUS; the primary system
detects this (if path status is normal) and changes P-VOL status
to PSUS.
When a pair is released from the secondary system, the
secondary system changes the status of the S-VOL to SMPL.
The primary system detects this (if path status is normal and
changes P-VOL status to PSUS. (The pair must be released
from the primary system to change P-VOL status to SMPL.)
See "PSUS types and behaviors" (page 71)
The pair is suspended due to an error; the pair is not
synchronized.
The primary and secondary systems keep track of any journal
data that are discarded during the suspension operation.
The primary system keeps track of P-VOL tracks that are
updated while the pair is suspended.
When a Cnt Ac-J suspension condition is detected, the primary
system changes P-VOL and S-VOL status to PSUE. If the
secondary system detects the condition, it changes the S-VOL
status to PSUE; the primary system detects this and changes
P-VOL status to PSUS.
See "PSUE types and behaviors" (page
