Table 5 Suspend Types
Description Applies to Suspend Type
The user suspended the pair from the primary storage system or
secondary storage system using the secondary data volume option. Primary data

by operator
The secondary storage system received a request from the primary
storage system to suspend the volume pair. The primary data volume
suspend type is Primary data volume by Operator or Secondary data
volume by Operator. Secondary data
volume By MCU
The primary storage system detected an error condition at the secondary
storage system which caused the primary storage system to suspend the
URz volume pair. The secondary data volume suspend type is By MCU. Primary data volume By RCU
The primary storage system detected that the secondary data volume
status changed to simplex because the user released the pair from the
secondary storage system. The pair cannot be resumed because the
secondary data volume does not have the suspended status. Primary data volume Delete Pair to
RCU
The primary storage system detected an error during communication
with the secondary storage system or an I/O error during update copy.
In this case, the secondary data volume suspend type is usually By MCU. Primary data volume Secondary
Data Volume
Failure
The primary storage system could not find valid control information in
its nonvolatile memory during the IMPL procedure. This condition occurs
only if the primary storage system is completely without power for more
than 48 hours (for example, power failure and fully discharged backup
batteries). Primary data

The volume pair was suspended before the initial copy operation was
complete. The data on the secondary data volume is not identical to the
data on the primary data volume. Primary data

The data volume pair was suspended because it was highly likely that
journal data will overflow. Primary data

Table 6 Consistency Status for Suspended URz Secondary Data Volumes
Description Consistency Status
This URz volume pair was suspended alone. Update sequence consistency between this
secondary data volume and other secondary data volumes in this journal group is not
ensured. This secondary data volume cannot be used for disaster recovery at the secondary
system. This status is indicated when:
• This volume pair was suspended by a user-initiated suspend pair operation with the
URz Suspend option set to Volume.
•
This volume pair was suspended due to a failure that did not affect the entire consistency
group, and the Error Level pair option for this pair is set to Volume.
Volume
This URz volume pair was suspended along with the other pair in its journal group. Update
sequence consistency between this secondary data volume and other secondary data
volumes in this journal group is ensured. This secondary data volume can be used for
disaster recovery at the secondary system (after releasing the URz volume pair from the
secondary storage system). This status is indicated when:
•
This volume pair was suspended by a user-initiated suspend pair operation with the
URz Suspend option set to Group.
• All volume pairs in this journal group were suspended due to a failure that affected
the entire journal group (not just one pair) (for example, primary storage
system-secondary storage system communication failure).
•
The volume pair was suspended due to a failure that did not affect the entire group.
