Table 12 Status of the Mapping Paths in the Mapping Path Information Dialog Box (continued)
Displayed Item | Description |
External device | The setting of the external storage system has been changed. For example, the |
setting changed | path definition was deleted, or the external storage system itself was replaced |
| by another device. |
|
|
LDEV size reduced | The setting of the volume capacity of the external storage system has been |
| changed (the volume capacity was reduced). |
|
|
Not ready | The reply from the external storage system was NOT READY. |
|
|
Illegal request | The reply from the external storage system was ILLEGAL REQUEST. |
|
|
Command aborted | The reply from the external storage system was ABORTED COMMAND. |
|
|
Busy | The external storage system is busy. |
|
|
LDEV reserved | The external storage system is reserved. |
|
|
Response error | The external storage system is blocked due to an abnormal reply. |
|
|
Initiator port | The port attribute of the external storage system has been changed to the initiator |
| port. |
|
|
Unknown port | The port attribute of the external storage system is unknown. |
|
|
Cannot detect port | The path has been removed or the port of the external storage system cannot be |
| found. |
|
|
Internal error | The program error occurred or there is a logical contradiction. |
|
|
Timeout | Processing was retried because an abnormal reply was returned, however, the |
| processing has timed out. |
|
|
Passive | The port of the external storage system is not active. The port status is normal but |
| the port is not used for I/O. |
|
|
Standby | The port of the external storage system is standing by. The port status is normal |
| but cannot receive I/O. |
|
|
Target error | Port failures, such as controller blockade, are detected on the external storage |
| system side. |
|
|
Checking | The process of checking the mapping path status is in progress. |
|
|
Disconnect | Connection to the external storage system or the external volume is intentionally |
| stopped using the Disconnect Subsystem command or the Disconnect Volume |
| command. |
|
|
Unavailable | The reply from the external storage system was Unavailable. The external storage |
| system demands to change the connected port. Once the status becomes |
| Unavailable, the primary path is changed to the alternate path that is in the |
| Standby status. When the primary path changes, the status of the path becomes |
| Normal. |
|
|
Backoff | The reply from 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 is changed to the other status. |
Device check error An external volume is mapped, but you cannot access the volume in the external storage system.
Medium error | The volume in the external storage system becomes inaccessible. |
