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. |
