This pair is not yet synchronized.

• The pair is synchronized
• Updates from the host to the P-VOL are duplicated
in the S-VOL.

• When a pair is split from the primary system, that
system changes the status of the P-VOL and S-VOL
to Split.

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.
Read onlyRead/writePSUE (pair

• The primary system has suspended the pair due
to an error condition.
Read only if P-VOL
fence level is Data.
• 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.
Read onlyRead/writeThe status of the Continuous Access Synchronous
LUSE pair is COPY or PAIR, but the status of one or
PDUB
more individual LDEV pairs within the Continuous
Access Synchronous LUSE pair is SMPL or PSUE due
to an error condition.
