108 Troubleshooting
Applies to Description
P-VOL, S-VOL The primary storage system could not find
valid control information in its nonvolatile
memory during the IMPL procedure. This
error occurs only if the primary storage
system is without power for more than 48
hours (power failure and fully discharged
batteries).
P-VOL, S-VOL The primary storage system suspended
this pair during the initial copy operation.
The data on the S-VOL is not identical to
the data on the P-VOL.
S-VOL The primary storage system suspended all
Cnt Ac-J pairs because the primary
storage system was powered off.
Causes of suspension
Hardware redundancy has been lost due
to some blockade condition. As a result,
one of the following could not complete:
primary-secondary 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 system failed to create and
transfer journals due to unrecoverable
hardware failure.
The secondary system failed to receive
and restore journals due to
unrecoverable hardware failure.
The drive parity group was in
correction-access status while the Cnt
Ac-J pair was in COPY status.
Communication between the systems
failed because the secondary system or
network relay devices were not running.
Journal volumes remained full even after
the timeout period elapsed.
Corrective action
Restore the pair (pairresync) from the
primary storage system. The primary storage
system performs an initial copy operation in
response to the pairresync request, so that
the entire P-VOL is copied to the S-VOL.
Release the pair from the primary storage
system. Clear all error conditions at the
primary storage system, P-VOL, secondary
storage system, and S-VOL. Restart the initial
copy operation by using the Paircreate
dialog box.
None. The primary storage system
automatically restores these Cnt Ac-J pairs
when the primary storage system is powered
on.
SIM Recovery procedure
DC0x According to SIM, remove the hardware
DC1x blockade or failure.
DC2x
Restore the failed volume pairs (Pairresync) .
If a failure occurs during execution of the
RAID Manager horctakeover command,
secondary volumes in SSWS pair status may
remain in the master journal . If these volumes
remain, execute the pairresync -swaps
command on the secondary volumes whose
pair status is SSWS (pairresync is the RAID
Manager command for resynchronizing pair
and -swaps is a swap option. This operation
changes all volumes in the master journal to
primary volumes. After this operation, restore
the volume pairs (Pairresync).
DC0x Remove the failure from the primary and
secondary systems or the network relay
DC1x
devices.
If necessary, increase resources as needed
(for example, the amount of cache, the
number of paths between primary and
secondary systems, the parity groups for
journal volumes, etc.).
Restore the failed pairs (Pairresync).
