* To restore a path, delete and then add the path again. It may be necessary to delete and then add the RCU again.
To delete the RCU or path, see “Deleting Continuous Access Synchronous” (page 71) or “Deleting remote paths”
(page 70) . To re-register, see “Setting up primary and secondary systems for Cnt Ac-S” (page 46) . If you cannot restore
the path after performing these operations, contact HP for assistance.
Split pair problems
The following table provides a list of split pair problem types.
Corrective action Description Applies to Pair status/type
Clear the error condition at the secondary system
or S-VOL, then resynchronize the pair from the
primary system. The primary system detected an
error condition at the secondary
system, which caused the primary P-VOL PSUE (pair

/ by RCU
If you need to access the S-VOL to clear the error
conditions, release the pair from the secondary
system to split the pair. The S-VOL
split type is S-VOL Failure.

S-VOL, restart the pair.

the secondary system, or detected
an I/O error during update copy.
•
Clear any error conditions at the secondary
system or S-VOL, then resynchronize the pair
from the primary system.
In this case, the split type for the
S-VOL is usually S-VOL Failure.
•
If you need to access the S-VOL to clear the
error conditions, release the pair from the
secondary system. After you clear the error
conditions, recreate the pair.
Resynchronize the pair from the primary system.
An entire initial copy operation will be performed
in response to the pairresync request. The primary system could not find
valid control information in its
nonvolatile memory during the P-VOL,

IMPL procedure. This error occurs
only if the system is without power
for more than 48 hours (for
example, power failure or fully
discharged batteries).
Release the pair from the primary system. Clear
all error conditions on the primary system, P-VOL,
secondary system, and S-VOL. Recreate the pair. The primary system split this pair
during the initial copy operation.
The data on the S-VOL is not
identical to the data on the P-VOL. P-VOL,

Troubleshooting using RAID Manager
When an error occurs in pair operations using RAID Manager, you can identify the cause of the
error by referring to the RAID Manager operation log file. This file is stored in the following directory
by default:
/HORCM/log*/curlog/horcmlog_HOST/horcm.log
