Check the following table for the problem. After removing an error, retry the operation.

Possible causes

volume.

An error occurred in the switch, or the switch is off.

The cables are not properly connected.

The external volume was deleted in the external system.

An error occurred in the external volume.

The path is changed in the external system.

The number of mapped volumes exceeds the maximum number
(63,232) available for the local storage system.

There are not enough LDKC:CU:LDEV numbers available for
external volume mapping.

The external path is blocked.

See the problem above, “Remote Web Console cannot access
the external volume”. If the problem persists after correcting any
errors, continue to the next item.

Confirm that the cable between the local and external system is
connected properly.

If the cable is properly connected, disconnect it and then
reconnect. After 30 seconds, check the path status.

If the path is not restored, call the HP Technical Support.

See

“Troubleshooting external path status” (page 69)

.

Action is required for a path status in the View
External LUN Properties dialog box.

Perform any required action in the message and then retry the
operation. If the problem persists, see

“Troubleshooting port and

volume discovery problems” (page 75)

.

The volume in the external system cannot be found
even after port discovery or volume discovery was
performed.
