5 suspend types – HP StorageWorks XP Remote Web Console Software User Manual
Page 49
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).

Description
Secondary
data volume
by operator
Primary data
volume, secondary
data volume
The user suspended the pair from the primary storage system or
secondary storage system using the secondary data volume option.
By MCU
Secondary data
volume
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.
By RCU
Primary data
volume
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.
Delete Pair to
RCU
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.
Secondary
Data Volume
Failure
Primary data
volume
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.
MCU IMPL
Primary data
volume, secondary
data volume
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 (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.
JNL Cache
Overflow
Primary data
volume, secondary
data volume
The data volume pair was suspended because it was highly likely that
journal data will overflow.
MCU P/S
OFF
Secondary data
volume
The primary storage system is powered off.
