A split (or suspended) XP Continuous Access Async S-VOL has an additional status called consistency
status. The consistency status is displayed only at the RCU and indicates the S-VOL's update
sequence consistency with respect to other S-VOLs in the same group.
Table 7 XP Continuous Access split types (PSUS)
Description Applies to Type
You split the pair from the MCU using the
P-VOL Failure option. S-VOL split type is
PSUS-by MCU. P-VOL (XP Continuous
Access Sync only) PSUS, P-VOL by
Operator
You split the pair from the MCU or RCU using
the S-VOL option. P-VOL, S-VOL PSUS, S-VOL by
Operator
The RCU received a request from the MCU to
split the pair. P-VOL split type is PSUS-P-VOL
by Operator or PSUS-S-VOL by Operator. S-VOL PSUS, by MCU
The MCU detected the S-VOL status changed
to SMPL because you deleted the pair
(pairsplit-S) from the RCU. The pair cannot be
resumed because the S-VOL does not have
the PSUS/PSUE status. P-VOL PSUS, Delete pair to
RCU
Table 8 (page 27) describes the consistency status for split or suspended XP Continuous Access
Async S-VOLs (consistency status is displayed only at the RCU).
Table 8 Consistency status descriptions for split/suspended XP Continuous Access Async S-VOLs
Description Consistency status
(displayed at RCU)
XP Continuous Access Asynchronous volume pair was probably
split or suspended alone. Update sequence consistency between
this S-VOL and other S-VOLs in this consistency group is not
ensured. This S-VOL cannot be used for disaster recovery at the
secondary site. This status is indicated when:
•
You split this pair using the Suspend Range-LU pairsplit-r
option.
•
This pair was suspended due to a failure that did not affect
the entire consistency group, and the Error Level pair option
for this pair is set to LU.
Volume
XP Continuous Access Asynchronous volume pair was split or
suspended with other pairs in its consistency group. Update
sequence consistency between this S-VOL and other S-VOLs in
this consistency group is ensured. This S-VOL can be used for
disaster recovery at the secondary (remote) system (after deleting
the XP Continuous Access Async pair from the RCU). This status
is indicated when:
• You split this pair using the Suspend Range-Group pairsplit-r
option.
•
All pairs in this consistency group were suspended due to a
failure that affected the entire consistency group, not just one
pair (for example, MCU-RCU communication failure).
•
One pair in the group was suspended due to a failure that
did not affect the entire group, and the Error Level pair option
for this pair is set to Group.

XP Continuous Access suspend types
“XP Continuous Access suspend types” (page 28) describes XP Continuous Access suspend types,
which indicate the reason for suspension. Only the MCU can suspend XP Continuous Access
