• In RWC, when the operation is performed on the
primary system, the status of both the P-VOL and
S-VOL changes to Suspend.
ON, otherwise
No.
• In RWC, when the operation is performed on the
secondary system, the status of the S-VOL changes
to Suspend; the primary system detects this and
changes P-VOL status to Suspend.
BCM suspend statuses initiated by the user:
• SUSPOP (03): The user performed a split operation
on the P-VOL. The update information is not reflected
in S-VOL.
• SUSPOP (04): The user performed a split operation
on the S-VOL. The P-VOL can be updated, and the
update information is recorded as differential data.
• SWAPPING (04): The pair was split in the REVERSE
direction (S-VOL to P-VOL).
• SUSPER (07): The P-VOL was split by the system
because the user deleted the pair from the S-VOL
side.

• The primary system keeps track of P-VOL tracks that
are updated while the pair is suspended.
• In RWC, when a Cnt Ac-J Z suspension condition
is detected, the primary system changes P-VOL and
S-VOL status to Suspend. If the secondary system
detects the condition, it changes the S-VOL status
to Suspend; the primary system detects this and
changes P-VOL status to Suspend.
BCM suspend statuses initiated by the primary or
secondary system:
• SUSPOP (05): The secondary system received a
split request from the primary system and split the
pair.
• SUSPCU (06): The primary system split the pair
because it detected an error in the secondary
system.
• SUSPCU (08): The pair was split because the
primary system detected an error during
communication with the secondary system or
detected an I/O error during update copy.
• SUSPER (09): The pair was split because the
primary system detected volatilization of pair control
information on memory when power was ON
(IMPL). This error occurs when power-off status of
