Primary

system
hardware or
secondary
storage
system
hardware Hardware redundancy has been lost due to
some blockade condition. As a result, one of the
following could not complete: primary-secondary
storage system communication, journal creation,
copy operation, restore operation, staging
process, or de-staging process.
Journals cannot be retained because some portion of
the cache memory or the shared memory has been
blocked due to hardware failure.
The primary storage system failed to create and
transfer journals due to unrecoverable hardware
failure.
The secondary storage system failed to receive and
restore journals due to unrecoverable hardware
failure.
The drive parity group was in correction-access
status while the URz pair was in Pending Duplex
status.
DC0

DC1

DC2
x According to SIM, remove the
hardware blockade or failure.
Restore the failed volume pairs (Resume
Pair).
If a failure occurs when Business
Continuity Manager is being used,
secondary volumes in Suspend
(equivalent to SWAPPING in Business
Continuity Manager) may remain in the
master journal group. If these volumes
remain, execute the YKRESYNC
REVERSE option on the secondary
volumes whose pair status is Suspend,
which is equivalent to SWAPPING in
Business Continuity Manager
terminology (YKRESYNC is the
Business Continuity Manager command
for resynchronizing pair). This operation
changes all volumes in the master
journal group to primary volumes. After
this operation, restore the volume pairs
(Resume Pair).
Communicatio
n between the
primary and
secondary
storage
systems Communication between the storage systems
failed because the secondary storage system or
network relay devices were not running.
Journal volumes remained full even after the timeout
period elapsed.
DC0
x
DC1
x Remove the failure from the primary
and secondary storage systems or
the network relay devices.
If necessary, increase resources as
needed (e.g., the amount of cache, the
number of paths between primary and
secondary storage systems, the parity
groups for journal volumes, etc.).
Restore the failed pairs (Resume Pair).
RIO overload
or RIO failure An unrecoverable RIO (remote I/O) timeout
occurred because the storage system or
networks relay devices were overloaded. Or, RIO
could not be finished due to a failure in the
storage system. DC2
x Release failed pairs (Delete Pair).
If necessary, increase resources as
needed (e.g., the amount of cache, the
number of paths between primary and
secondary storage systems, the parity
groups for journal volumes, etc.).
Re-establish failed pairs (Add Pair).
Planned power
outage to the
primary
storage
system The URz pairs were temporarily suspended due
to a planned power outage to the primary
storage system. DC8
x No recovery procedure is required.
The primary storage system will
automatically remove the suspension
condition when the storage system is
powered on.
Universal Replicator for z/OS ® Software Error Codes
Storage Navigator computers display an error message when an error occurs
during URz operations. The error message describes the error and displays an
error code consisting of four digits. The error message may also include a
USP V SVP error code. If you need to call the Hitachi Data Systems Support
Center for assistance, please report the URz and SVP error code(s). Please
refer to Storage Navigator Messages for a list of error codes displayed on the
Storage Navigator computers.
