Table 5 Continuous Access XP Journal split types (PSUS)
Type Applies to Description
PSUS, P-VOL by
Operator
Primary data
volume
The secondary data volume's split type is PSUS-by MCU.
PSUS, S-VOL
by Operator
Primary data
volume, Secondary
data volume
You split the pair from the primary or secondary array using the
secondary data volume option.
PSUS, by MCU Secondary data
volume
The secondary array received a request from the primary array to
split the pair. The primary data volume's split type is PSUS-P-VOL
by Operator or PSUS-S-VOL by Operator.
PSUS, by RCU Primary data
volume, Secondary
data volume
The primary array detected an error condition at the secondary
array that caused the primary array to suspend the Continuous
Access XP Journal data volume pair. The secondary data volume
suspend type is PSUE-S-VOL Failure.
PSUS,
Pairsplit-S to
RCU
Primary data
volume
The primary array detected that the secondary data volume's status
changed to SMPL because you deleted the pair (pairsplit-S) from
the secondary array. The pair cannot be resumed because the
secondary data volume does not have the PSUS/PSUE status.
PSUS, JNL
Cache
Overflow
Primary data
volume, Secondary
data volume
The data volume pair was suspended because it was highly likely
that the journal data would overflow.
NOTE:
RAID Manager XP displays this split type as PFUS.
Table 6 Consistency status for split/suspended Continuous Access XP Journal
secondary data volumes
Consistency status
(displayed at
secondary array)
Description
Volume This Continuous Access XP Journal data volume pair was split or suspended from
by itself (as opposed to split as a group). Update sequence consistency between
this secondary data volume and the other secondary data volume in this journal
group is not ensured. You cannot use the secondary data volume for disaster
recovery at the secondary site. This status is indicated when:
• You split the pair using the Suspend Range-Volume (LU) pairsplit option.
• The pair was suspended due to a failure that did not affect the entire journal
group.
Group This Continuous Access XP Journal data volume pair was split or suspended with
the other pairs in its journal group. Update sequence consistency between the
secondary data volume and other secondary data volumes in this journal group
is ensured. You can use this secondary data volumes for disaster recovery at the
secondary system (after deleting the Continuous Access XP Journal data volume
pair from the secondary array). This status is indicated when:
• You split the pair using the Suspend Range-Group pairsplit option.
• All pairs in this journal group were suspended due to a failure that affected the
entire journal group, not just one pair (for example, a primary array-secondary
array communication failure).
• One pair in the group was suspended due to a failure that did not affect
the entire group.
