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 “
” on page 48 for
suspend types)
This data volume pair is not synchronized.
− When the primary storage system
detects a URz suspension condition (see
” 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
” 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
simplex. When the delete pair operation is requested
(by user), the status of all affected pairs changes to
deleting (releasing). When the delete pair operation
is complete, the status changes to simplex.
