for Command View XP or XP Remote Web Console, this SIM results in an SNMP trap indicating the
reason for the suspension.
• Continuous Access XP Journal pair status
The Continuous Access XP Journal Suspending and Deleting transitional states occur when a request
to change the Continuous Access XP Journal pair status is accepted, but the requested status change
(PSUS, PSUE, or SMPL) is not complete yet. These states are not reported to the host. For Suspending,
either you or the primary array can request the status change. For Deleting, only you can request
the status change. If you requested the status change, the final status is reported at the end of the
transition. If an error caused the status to change to PSUE, the suspended status is reported at the
beginning of the transition.
After an array receives a request to split or delete a pair in Flush mode, the status of the pair remains
in the Suspending or Deleting state until the journal in the master journal group is restored to the
restore journal group and the pair is completely split or deleted. To calculate the time during which
the pair remains in the Suspending or Deleting state, use the following equation:
C × (u ч 100) Ч 1,024 ч V
where:
• C is the master journal volume's total capacity (in megabytes).
• u is the master journal volume's data usage rate (as a percentage).
• V is the data transfer speed between the primary and secondary arrays. The unit is MB/s
(megabytes per second).
To find a journal volume's usage rate, use the monitoring feature (see
Monitoring remote copy
operations ).

SMPL (simplex) Volume is not currently assigned to a
Continuous Access XP Journal data volume
pair and does not belong in the journal
group. When this volume is added to a
Continuous Access XP Journal data volume
pair, its status changes to COPY.
Read / Write Read / Write
COPY Initial copy operation for this pair is in
progress. This data volume pair is not yet
synchronized. When the initial copy is
complete, the status changes to PAIR.
Read / Write Read Only
PAIR Data volume pair is synchronized. Updates
to the primary data volume are duplicated
on the secondary data volume.
