Table 32 Mapping Path Statuses and Required Actions (continued)
Status | Description |
Device check error | An external volume is mapped, but |
| you cannot access the volume in the |
| external storage system. |
Action
Check the status of the volume in the external storage system and recover the volume if it is not normal.
Format the volume if it is not formatted.
Medium error | The volume in the external storage |
| system becomes inaccessible. |
Check the status of the volume in the external storage system and recover the volume if it is not normal.
Format the volume if it is not formatted.
Troubleshooting Volume Discovery
Table 33 (page 130) shows the causes of port discovery failure or volume discovery failure, and actions required to troubleshoot the failure.
Table 33 Causes of Volume Discovery Failure and Required Actions
Cause
Remote Web Console is not in the Modify mode.
Port of the local storage system and port of the external storage system are not connected.
Cable for the switch is not connected appropriately. Or the port of the switch is blocked.
Zoning for the switch is not set appropriately.
Action
Change to the Modify mode and retry the operation.
Connect the external port of the local storage system and the port of the external storage system.
Connect the cable to the correct port of the switch. Or change the port status of the switch into the normal status.
Make sure the zone configuration is correct so that the external port of the local storage system can communicate with the port of the external storage system.
External storage system is not connected to the port set to External of the local storage system.
External volume cannot be used because the used external port is in the Internal/External MIX mode. This problem occurs when the external volume is not a command device.
External volume returned RESERVATION CONFLICT. Port security is set on the external storage system.
Connect the external storage system to the External port of the local storage system. Or change the connected port to External.
Perform one of the following:
•Use the external port in the Standard mode.
•Change the Internal/External MIX mode of the external port to the Standard mode.
Release the reserved state of the external volume.
Cancel the port security setting or change the security of the external storage system so that the local storage system can access the port of the external storage system.
No LU is configured on the port of the external storage system.
Capacity of the external volume is less than the supported capacity of XP External Storage.
Configure an LU on the port of the external storage system.
Perform one of the following:
•Increase the capacity of the external volume so that the capacity of the external volume is equal to or larger than the capacity supported by XP External Storage.
•Use a security function or delete the LU setting from the port of the connected external storage system so that the local storage system cannot recognize the volume with insufficient capacity.
