Pair Status

Description

Simplex

This volume is not currently assigned to a URz data

volume pair. This volume does not belong in the

journal group. When this volume is added to a URz

data volume pair, its status will change to pending

duplex.

Pending Duplex

The initial copy operation for this pair is in progress.

This data volume pair is not yet synchronized. When

the initial copy is complete, the status changes to

duplex.

Duplex

This data volume pair is synchronized. Updates

to the primary data volume are duplicated on the

secondary data volume.

Suspended (see

Suspend Types

” on page 48 for

suspend types)

This data volume pair is not synchronized.
− When the primary storage system

detects a URz suspension condition (see

Suspension Condition

” on page 50), the primary

storage system changes the primary data volume

status and secondary data volume status (if possible)

to suspended.
− When the secondary storage system

detects a URz suspension condition (see

Suspension Condition

” on page 50), the secondary

storage system changes the secondary data volume

status to suspended.
− When you suspend a pair from the primary storage

system, the primary storage system changes the

status of the primary data volume and secondary

data volume (if possible) to suspended. When you

suspend a pair from the secondary storage system,

the secondary storage system changes the status of

the secondary data volume to suspended.
− When the primary storage system detects that the

pair was suspended or released from the secondary

storage system, the primary storage system changes

the status of the primary data volume to suspended.

Suspending

This pair is not synchronized. This pair is in transition

from duplex or pending duplex to suspended. When

the suspension is requested (by user, primary storage

system, or secondary storage system), the status of

all affected pairs changes to suspending. When

the suspension is complete, the status changes to

suspended.

Deleting (releasing)

This pair is not synchronized. This pair is in transition

from duplex, pending duplex, or suspended to

(by user), the status of all affected pairs changes to
