Description
This volume is not currently assigned to a Continuous
Access Synchronous pair.
The initial copy operation for this pair is in progress.
This pair is not yet synchronized.
The pair is synchronized
Updates from the host to the P-VOL are duplicated
in the S-VOL.
The user has split the pair.
The pair is not synchronized.
When a pair is split from the primary system, that
system changes the status of the P-VOL and S-VOL
to Split.
When a pair is split from the secondary system,
the secondary system changes the status of the
S-VOL to Split. The primary system detects this (if
path status is normal) and changes P-VOL status
to Split.
When a pair is release from the secondary
system, that system changes the S-VOL status to
SMPL. The primary system detects this (if the path
status is normal) and changes the P-VOL status to
Split. The pair must be released from the primary
system in order to change P-VOL status to SMPL.
The primary system has suspended the pair due
to an error condition.
The pair is not synchronized.
If the primary system cannot keep the pair
synchronized for any reason, it changes the status
of the P-VOL and S-VOL (if possible) to Split.
The status of the Continuous Access Synchronous
LUSE pair is COPY or PAIR, but the status of one or
more individual LDEV pairs within the Continuous
Access Synchronous LUSE pair is SMPL or PSUE due
to an error condition.
