124 Troubleshooting External Storage XP
Cannot detect port Status: The path was removed or the external
array’s port cannot be found. There is a problem
with the connection to the external array. The
following are possible causes:
• The fibre cable is not connected properly.
• The topology setting between the external and
target ports does not match.
• Because security is set on the port, the external
array’s device cannot be recognized from the
local array.
• If the external array is connected through
switches, the switches’ settings might not be
appropriate.
Corrective action: Check the condition of the
connection to the external array. If you cannot
restore the path, contact your HP account support
representative.
Internal error
Status: A program error occurred, or there is a
logical contradiction.
Corrective action: Contact your HP account support
representative.
Timeout Status: Processing was retried because an abnormal
reply (Response) was returned, but processing has
stopped due to a timeout.
Corrective action: The external array’s port of is
recognized. Check the condition of the connection
(for example, cables and switches) to the external
array. If you cannot restore the path, contact your
HP account support representative.
Target error Status: An error, such as blockade of the controller,
was found in the external array’s port.
Corrective action: Check the status of the external
array’s ports. If you cannot restore the path, contact
your HP account support representative.
Unavailable Status: The reply from the external array was
Unavailable. The external array requested a change
to the connected port. When the status becomes
Unavailable, the primary path changes to the
alternate path that is in Standby status. When the
primary path changes, the path status becomes
Normal.
Corrective action: If the path does not change
properly, check the external array’s status. If you
cannot restore the path, contact your HP account
support representative.
