Troubleshooting by suspension type
The following table provides troubleshooting information for suspended pairs by suspension type.

|
PSUE, by RCU |
P-VOL |
The primary system suspended a pair because it detected an error condition in the secondary system. The suspend type for the S-VOL is by MCU. |
Clear the error condition at the secondary system or S-VOL. If you need to access the S-VOL, release the pair from the primary system. If data in the S-VOL has been changed, release the pair from the primary system and then re create the pair by using the paircreate dialog box. If data in the S-VOL has not been changed, resynchronize the pair from the primary system. |
|
PSUE, S-VOL Failure |
P-VOL |
The primary system detected an error during communication with the secondary system or detected an I/O error during update copy. In this case, the suspend type for the S-VOL is usually by MCU. |
Check the path status on the DKC Status dialog box (see Remote path status problems).Clear any error conditions at the secondary system and the S-VOL. If you need to access the S-VOL, release the pair from the secondary system. If data in the S-VOL has been changed, release the pair from the primary system and then re create the pair by using the paircreate dialog box. If data in the S-VOL has not been changed, resynchronize the pair from the primary system. |
|
PSUE, MCU IMPL |
P-VOL, S-VOL |
The primary system could not find valid control information in its nonvolatile memory during the IMPL procedure. This error occurs only if the primary system is without power for more than 48 hours (power failure and fully discharged batteries). |
Resynchronize the pair from the primary system. The primary system performs an initial copy operation in response to the pairresync request, so that the entire P-VOL is copied to the S-VOL. |
|
PSUE, Initial Copy Failed |
P-VOL, S-VOL |
The primary 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. |
Release the pair from the primary system. Clear all error conditions at the primary system, P-VOL, secondary system, and S-VOL. Restart the initial copy operation by using the Create UR Pairs window. |
|
PSUE, MCU P/S OFF |
S-VOL |
The primary system suspended all Universal Replicator pairs because the primary system was powered off. |
None. The primary system automatically resynchronizes these Universal Replicator pairs when the primary system is powered on. |
