Device Manager - Storage Navigator hangs, or Universal Replicator operations do not function properly.

Make sure that the problem is not being caused by the computer or Ethernet hardware or software, and restart the computer. Restarting the Device Manager - Storage Navigator computer does not affect Universal Replicator operations in progress.

Make sure that Universal Replicator requirements are met.

Make sure that the primary and secondary systems and remote copy connections are powered on, and that NVS and cache are fully operational.

Check all the entered values and parameters to make sure that you entered the correct information on the Device Manager - Storage Navigator computer (for example, secondary system serial number, path parameters, P-VOL and S-VOL IDs).

If you are using Performance Monitor, refrain from using it.

An initiator channel-enable LED indicator (on the control window of the storage system) is off or flashing.

Please call Hitachi Data Systems customer support for assistance.

Status of pairs or remote paths is not displayed correctly.

Check whether you selected the correct items and options in the Device Manager - Storage Navigator windows.

A Universal Replicator error message appears on the Device Manager - Storage Navigator computer.

Remove the error cause, and then retry the Universal Replicator operation.

The status of a remote path is not normal.

Check the path status in the View Remote Connection Properties window, and see Remote path status problems.

The pair status is suspended.

Check the pair status in the View Pair Properties window, and see Troubleshooting by suspension type for suspend types and corrective action.

The create pair or resync pair operation resulted in a timeout error.

• If the timeout error was caused by a hardware failure, a SIM is generated. See Service information messages (SIMs) . If necessary, call Hitachi Data Systems customer support, and retry Universal Replicator operations after the problem is solved.

• If no SIM was generated, wait for a while (5 or 6 minutes), and then check the status of the pairs being created or resynchronized. If the pair status changed correctly, the failed operation completed after the timeout message was issued. If the pair status did not change as expected, heavy workload might have prevented the Universal Replicator operation from being completed. In this case, retry the Universal Replicator operation when the system has a lighter workload.

• If a timeout error occurs during the paircreate operation, the copy operation might not have been executed correctly in the order specified in the Priority field. A timeout error can be caused by a CU configuration or remote copy path error. Review the error, release the pair with the error, and then retry the paircreate operation.

A communication error between Device Manager - Storage Navigator and the SVP occurred.

See the Hitachi Command Suite User Guide for instructions.

Journal volumes are not registered in the journal

The error caused the delete journal operation to suspend. Re-register the journal volumes that belong to the journal, and then delete the journal again.

The pairresync operation suspends with a warning message.

This is caused when the following two conditions exist:

• The Preview list contains two or more pairs belonging to the same mirror.

• Mirror is defined in the Range column for at least one of the above pairs.

To continue processing, do either of the following:

• Ensure that the Range column displays LU for all pairs in the same mirror.

• In the Preview list, delete all but one pair in the same mirror.

An error occurs when Apply is clicked for a pair operation.

The error code appears in the right-most column of the Preview list. To view detailed information about the error, right click the error code and select Error Detail.

The pairs cannot be deleted after the pair operations because the pair status changed to Suspending or Deleting.

See Deleting the pairs in a mirror and specify Force for Delete Mode.
