(see Table 5 for

split types)

Data volume pai

r is not synchronized

because you sp

lit this pair (pairsplit-r) or

deleted this p

air from the secondary array

(pairsplit-S

). For Continuous Access XP

Journal pair

s, the primary and secondary

arrays keep t

rack of any journal data

discarded du

ring the pairsplit-r operation.

While a pair

is split, the primary and

secondary a

rrays keep track of the updated

primary an

d secondary data volume tracks.

When you sp

lit a pair from the primary

array, the

primary array changes the status

of the primary and secondary data volumes

to PSUS. When you split a pair from the

secondary array, the secondary array

changes the secondary data volume's status

to PSUS.

The primary array detects this (if

When yo

PSUE (pair

suspended-error)

(see Table 7 for

suspend types)

Data volume pair is not synchronized

because the primary or secondary array

suspended the pair due to an error condition.

For Continuous Access XP Journal pairs, the

primary and secondary arrays keep track

of any journal data discarded during the

suspension operation. The primary array

keeps track of updated primary data volume

tracks while the pair is suspended.

For Continuous Access XP Journal pairs, if

the secondary array detects a Continuous

Access XP Journal suspension condition (see

Continuous Access XP Journal suspension

conditions), the primary array changes the

secondary data volume's status to PSUE.

For Continuous Access XP Journal pairs,

if the primary array detects a Continuous

Access XP Journal suspension condition (see

Continuous Access XP Journal suspension

conditions), the secondary array changes

the secondary data volume's status to PSUE.

The primary array detects this (if path

status is normal) and changes primary data

volume's status to PSUS.
