Table 5 General troubleshooting for External Storage (continued)
Corrective action Error
The reason for the error could be as follows:
• All the set paths are blocked (paths are not connected).
•
The attribute of external volume is not set to Read/ Write
attribute.
• The external volume is blocked by error.
A corresponding external volume was not found from the external
path with the highest priority. “?” is displayed in the LUN ID(Highest Priority)
column of the Discovered External Volumes table.
Confirm the connection with the external storage system that has
failed in the volume discovery, and perform the operation again.
Confirm the detail of the error from the discovery result, and confirm
the connection with an external storage system and the setting of
the external storage system, and perform the operation again. The external volume discovery process was not
completed because of failure.

The time required for the writing processing of data from the cache
to the external volume (destaging processing) depends on the
volume capacity (more time is required for the larger volume than
the smaller one). The processing speed is about 20 MB/s. However,
the processing speed depends on the performance and the status
of the external storage system.

If the device is blocked as a result of the device status transition,
see the error description "The external volume is blocked." in
“General troubleshooting for External Storage” (page 61) for the
corrective action.

Troubleshooting the mapping path
The following table describes the path statuses displayed in the Status column in the View External
LUN Properties window and the actions for them. The notes on connecting each storage system
as an external storage system are in
“Connecting external storage systems” (page 69) . See “Path
status and examples of recovery procedure (AMS/WMS)” (page 71) for settings of connection
and examples of recovery procedure, and then take corrective actions.
