Pair Status - HP StorageWorks P9000 User Manual

The number of bitmap areas affects the maximum possible number of pairs that can be created in
the storage system.

Pair status

Every pair operation results in a change in pair status. You should monitor pair status to insure
that an operation completed successfully. Also, pairs must have a specific status in order for specific
operations to be executed.
The following provides a brief description of the pair statuses. For complete details, see
definitions" (page 67)
SMPL: A volume that is not assigned to a pair is in Simplex status, SMPL.
COPY: When copy processing is started, the primary system changes the status of the P-VOL
and S-VOL to COPY.
PAIR: When the initial copy processing is complete, the primary system changes the status of
both data volumes to PAIR.
PSUE: When a pair is suspended due to an error condition, the primary system changes the
P-VOL and S-VOL status to PSUE (if the path status is normal).
PSUS:
When a pair is split by the user (pairsplit-r), the primary or secondary system changes
◦
the status of the P-VOL and S-VOL to PSUS (if the path status is normal).
If a pair is split from the secondary system, it changes the S-VOL status to PSUS. The
◦
primary system detects the split (if path status is normal) and changes the P-VOL status to
PSUS.
