Remote path status problems

The following table provides troubleshooting information for remote paths between storage systems.

Path status

Description

Recommended action

Normal

This path has been successfully established and can be used for UR copy activities.

None required.

Initialization Failed

The link initialization procedure to the secondary system failed because the physical path connection was missing between the primary and secondary systems.

  • Make sure that the primary and secondary systems are physically and correctly connected.

  • Make sure that you entered the correct secondary system serial number, model, and primary and secondary system port numbers.

  • Make sure that the topology settings (fabric, FC-AL, point-to-point) for the local storage system's port and the remote storage system's port are correct.

Communication Time Out

Communication between the primary and secondary systems timed out.

  • Make sure the secondary system is powered on and that cache is fully functional.

  • Make sure that network relay devices are properly configured and functional. This includes cables, connectors, switches, extender devices, communication lines, and all other devices connected to the extenders.

Port Rejected

The primary system rejected the logical path link control function because all logical path resources in the primary system are being used for other connections.

  • Delete all paths and secondary systems not in use.

  • Reconfigure the ports, and then add the paths and configure the secondary systems to the primary systems again.

Pair-Port Rejected

The secondary system rejected the logical path link control function because all logical path resources in the secondary system are being used for other connections.

Follow the same corrective actions in Port Rejected.

Serial Number Mismatch

The secondary system's serial number does not match the specified serial number.

  • Make sure that you entered the correct secondary system serial number and model, and primary and secondary system port numbers.

  • Make sure that the topology settings (fabric, FC-AL, point-to-point) for the local storage system's port and the remote storage system's port are correct.

  • Make sure that the data path relay equipment is properly configured and functional, including cables, connectors, switches, extender devices, communication lines, and all other devices connected to the extenders.

Invalid Port Mode

The specified port is not configured, or this path already exists.

  • Make sure that no two paths between primary and secondary system ports have the same settings.

  • Make sure that you entered the correct secondary system serial number and model, and primary and secondary system port numbers.

  • Make sure that the primary and secondary system ports are configured correctly.

  • Make sure that the data path relay equipment is properly configured and functional, including cables, connectors, switches, extender devices, communication lines, and all other devices connected to the extenders.

Communication Failed

The primary system connected to the secondary system successfully, but logical communication timeout occurred.

  • Make sure that the secondary system port and the relay equipment are configured correctly.

  • Make sure that the data path relay equipment is properly configured and functional, including cables, connectors, switches, extender devices, communication lines, and all other devices connected to the extenders.

In Progress

Paths are being created or deleted, or the port attribute is being changed.

Wait until processing is completed.

Logical Blockade

Blockaded due to continual path or link failure.

See the following.

The primary system port does not work.

Repair the port on the primary system, and then restore the path*.

The secondary system port does not work.

Repair the port on the secondary system, and then restore the path*.

The path relay equipment does not work.

Repair the path relay equipment, and then restore the path*.

The connection cable is physically broken.

Replace the broken cable, and then restore the path*.

Program Error

A program error is detected.

Restore the path*.

* To restore a path, delete and then add the path again. It might be necessary to delete and then add the secondary system again.

To delete the secondary system or path, see Deleting the Universal Replicator relationship or Deleting remote paths. To re-register, see Adding remote connections. If you cannot restore the path after performing these operations, contact Hitachi for assistance.
