Table 7 on page 50 lists and describes the consistency status descriptions for suspended URz secondary

data volumes.

When a URz pair is suspended, whether user-requested or due to failure, the primary storage system

generates sense information to notify the host(s).

The user suspended the pair from the primary storage system or

secondary storage system using the secondary data volume option.

The secondar

y storage system received a request from the primary

storage syst

em to suspend the volume pair. The primary data volume

suspend type

is PrimarydatavolumebyOperator or Secondary data

Primary data

volume

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.

Failure

Primary

data

volume

The prim

ary 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.

MCU IMPL

Primary data

volume, secondary

data volume

Theprimary storagesystem 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 (e.g., power failure and fully discharged

backup batteries).

Initial Copy

failed

Primary data

volume, secondary

data volume

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.
