This pair is not synchronized. This pair is in
transition from PAIR or COPY to PSUS/PSUE.
When the split/suspend pair operation is
requested, the status of all affected pairs
changes to Suspending. When the
split/suspend operation is complete, the status
changes to PSUS/PSUE. Suspending

This pair is not synchronized. This pair is in
transition from PAIR, COPY, or PSUS/PSUE to
SMPL. When the pairsplit-S operation is
requested, the status of all affected pairs
changes to Deleting (releasing). When the
pairsplit-S operation is complete, the status
changes to SMPL. Deleting (releasing)

The pair is prepared for the delta resync
operation. When the status of the primary data
volume is HOLD, the write data for the XP
Continuous Access Synchronous S-VOL is stored
in the master journal volume.
Only the delta resync, releasing, or the
changing pair option operation is allowed on
the pairs in HOLD status.
If the environment of the delta resync operation
to support remote command devices is used,
this status indicates that the conditions to
successfully execute the delta resync operation
are satisfied.
HOLD
- Read / Write
*1
The pair status changes to HOLDING while the
delta resync pair creation is in progress. Only
a delta resync operation, a releasing operation,
or a changing pair option are allowed on the
pairs while in the HOLDING status.
This status is displayed when the environment
of the delta resync operation to support remote
command devices is used.
If you execute the delta resync operation on a
pair in the HOLDING status, the operation may
fail. If you change Entire to Delta resync Failure
in the Change JNL Option dialog box, all
differential data will be copied to a secondary
data volume.
HOLDING
*4
Read Read / Write
*1
An error occurred on the pair in HOLD status.
When the status of the primary data volume is
HLDE, the write data for the XP Continuous
Access Synchronous S-VOL is not stored in the
master journal volume.
Only the recovering pair status to standby
(HOLD), releasing, or the changing pair option
operation is allowed on the pairs in HLDE
status.
HLDE
*1: Whether you can access the primary data volume depends on the status of the XP Continuous
Access Synchronous pair that shares the volume.
*2: The secondary data volume of the XP Continuous Access Journal pair in HOLD status uses two
mirrors. Whether you can access the secondary data volume depends on the status of the mirror
