The Device Manager - Storage Navigator computer hangs, or TrueCopy operations do not function properly.

• Make sure that the problem is not being caused by the PC or Ethernet hardware or software, and restart the PC. Restarting the Device Manager - Storage Navigator computer does not affect storage system operations.

• Make sure that all TrueCopy requirements and restrictions are met (for example, same LU type).

• Make sure that the primary and secondary system and data paths are powered on and fully operational (NVS, cache).

• Check all input values and parameters to make sure that you entered the correct information about the Device Manager - Storage Navigator computer (for example, secondary system S/N and ID, path parameters, P-VOL and S-VOL IDs).

An initiator channel-enabled LED indicator (on the storage system's control panel) is off or flashing.

Contact Hitachi Data Systems customer support.

The pairs and/or remote systems are not displaying correctly.

Make sure that the correct CU is selected.

A TrueCopy error message displays on the PC.

Resolve the error, and then try the TrueCopy operation again.

The remote system path status is not normal.

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

Pair status is PSUE.

See Split pair problems.

The paircreate or pairresync operation resulted in a timeout error.

• Hardware failure: If the timeout error was caused by a hardware failure, a SIM is generated. If this occurs, call service personnel, then retry TrueCopy operations after the problem is fixed.

• Heavy workload: If no SIM was generated, wait 5 or 6 minutes then check the pair's status.

- If 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 operation from being completed. Retry the operation when the system has a lighter workload.

• A communication error may have occurred between the Device Manager - Storage Navigator computer and SVP. See the Hitachi Command Suite User Guide for information and instructions.

There is a pinned track on a TrueCopy volume.

See the troubleshooting topic in the Hitachi TrueCopy® User Guide for more information.

Monitoring data is not updated though the Monitoring Switch option is set to Enable.

Because the time setting of SVP is changed, the monitoring data might not be updated. Disable Monitoring Switch, then enable again. For more information about Monitoring Switch, see the Hitachi Virtual Storage Platform G200, G400, G600 Performance Guide.
