Table 4 URz Data Volume Pair Status (continued)
DescriptionPair Status
This data volume pair is synchronized. Updates to the
primary data volume are duplicated on the secondary data
volume.
Duplex
• When the primary storage system detects a URz
suspension condition (see Suspension Condition), 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), 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.
This data volume pair is not synchronized.
Suspended (see Suspend Types for suspend types)
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.
Suspending
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.
Deleting (releasing)
The secondary storage system encountered a
non-time-stamped journal data for a URz pair using the
System timer type option. This status can be displayed at
the primary storage system and secondary storage system,
but the primary storage system may not have the most
current information. Always use the pair status information
displayed at the secondary storage system for disaster
recovery.
