Table 6 XP Continuous Access Asynchronous pair status descriptions (continued)
S-VOL access
P-VOL access
Description
Pair status
Read only; Read
and write, if
write enable split
option is
selected.
Read/write
Pair is not synchronized because
you split this pair (pairsplit-r) or
deleted this pair from the RCU
(pairsplit-S). For XP Continuous
Access Async pairs, the MCU and
RCU track recordsets discarded
during the pairsplit-r operation.
While a pair is split, the MCU and
RCU track P-VOL and S-VOL
cylinders updated.
When you split a pair from the
MCU, the MCU changes the status
of the P-VOL and S-VOL to PSUS.
When you split a pair from the RCU,
the RCU changes the status of the
S-VOL to PSUS. The MCU detects
this (if path status is normal) and
changes the P-VOL status to PSUS.
When you delete a pair from the
RCU, the RCU changes the S-VOL
status to SMPL. The MCU detects this
(if path status is normal) and
changes the P-VOL status to PSUS.
You must delete the pair from the
MCU to change the P-VOL status to
SMPL.
PSUS (pair
suspended-split)
(see
for
split types)
Read only
Read/write;
Read only if
fenced.
Pair is not synchronized because the
MCU or RCU suspended the pair
due to an error condition. For XP
Continuous Access Async pairs, the
MCU and RCU track recordsets
discarded during the suspension
operation. The MCU tracks P-VOL
cylinders updated while the pair is
suspended.
For XP Continuous Access
Synchronous pairs, if the MCU
cannot keep the pair synchronized
for any reason, the MCU changes
the status of the P-VOL and S-VOL
(if possible) to PSUE.
For XP Continuous Access
Asynchronous pairs, if the MCU
detects a suspension condition (see
“XP Continuous Access
Asynchronous suspension
conditions” (page 29)
), the MCU
changes the P-VOL and S-VOL status
(if possible) to PSUE.
For XP Continuous Access
Asynchronous pairs, if the RCU
detects a suspension condition (see
“XP Continuous Access
Asynchronous suspension
conditions” (page 29)
), the RCU
changes the S-VOL status to PSUE,
and the MCU detects this (if path
status is normal) and changes the
P-VOL status to PSUE.
