Table 32 Mapping Path Statuses and Required Actions (continued)
Status | Description |
Unknown port | The port attribute of the external |
| storage system is unknown. |
Action
The port of the external storage system is recognized. Check the condition of the connection (for example, cables, switches) to the external storage system. If you cannot restore the path, call HP technical support.
Cannot detect port | The path has been removed or the port |
| of the external storage system cannot |
| be found. There is a problem with the |
| connection to the external storage |
| system. The possible causes are: |
| • The fiber cable is not physically |
| connected in the proper way. |
| • The setting of the topology does |
| not match between the external |
| port and the target port. |
| • Because the security is set on the |
| port, the device of the external |
| storage system cannot be |
| recognized from the local storage |
| system. |
| • If the external storage system is |
| connected through switches, the |
| settings for the switches may not |
| be appropriate. |
Internal error | The program error occurred. Or there |
| is a logical contradiction. |
Timeout | The processing was retried because |
| the abnormal reply (Response) was |
| returned, however, the processing has |
| been stopped by timeout. |
Check the condition of the connection to the external storage system. If you cannot restore the path, call HP technical support.
Call HP technical support.
The port of the external storage system is recognized. Check the condition of the connection (for example, cables, switches) to the external storage system. If you cannot restore the path, call HP technical support.
Target error | An error such as the blockade of the |
| controller has been found in the port |
| of the external storage system. |
Check the status of the ports of the external storage system. If you cannot restore the path, call HP technical support.
Unavailable | The reply of the external storage |
| system was Unavailable. The external |
| storage system demands to change |
| the connected port. When the status |
| becomes Unavailable, the primary |
| path changes to the alternate path that |
| is in the Standby status. When the |
| primary path has been changed, the |
| status of the path becomes Normal. |
If the path is not changed over properly, check the status of the external storage system. If you cannot restore the path, call HP technical support.
Backoff | The reply of the external storage |
| system was Backoff. The status of the |
| path is waiting for recovery because |
| a temporary error has occurred in the |
| volume of the external storage system. |
| Even if the status of the primary path |
| becomes this status, the primary path |
| is not changed to the alternate path |
| immediately. After the error recovery, |
| the status becomes Normal. |
If the status cannot be recovered from the error, the path status changes to another status. React to the new path status after the status is changed. If you cannot restore the path, call HP technical support.
