	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.

Troubleshooting the Mapping Path

Table 32 (page 127) shows the description on the path statuses that are displayed in the Status column in the Mapping Path Information dialog box and the reactions for them. See “Connecting External Storage Systems” (page 134) for notes on connecting each storage system as an external storage system and for settings of connection and examples of recovery procedure, and then take corrective actions.

Table 32 Mapping Path Statuses and Required Actions

Status	Description	Action
