Table 11 General External Storage XP troubleshooting
Error Corrective action
The Command View XP
management station or XP
Remote Web Console cannot
access the external LU.
Correct the error and retry the operation.
The reason for the error could be one of the following:
• The Fibre Channel (FC) switch is off or an error occurred in the switch.
• The FC cables are not properly connected.
• The configuration of the external disk array changed, and the external LU was
deleted.
• An error occurred with the external LU in the external disk array.
• The path between the local disk array and external disk array changed.
• The port attribute of the local disk array is no longer external.
• The topology information is not set correctly.
If none of these are the problem, disconnect the cable between the local disk
array and external disk array, and reconnect it. Retry the operation after
30 seconds.
The external LU cannot be
mapped as an internal XP
LDEV of the local disk array.
Correct the error and retry the operation.
The source of the error could be any of the following:
• The number of mapped external LUs exceeds the maximum number (15,360
LUs for XP12000 or 8,192 LUs for XP10000) available for the local disk
array.
• There are not enough CU:LDEV numbers available for external LU mapping.
The path to the external LU is
blocked.
An error in the first row of this table (Error: The Command View XP or XP Remote
Web Console cannot access the external LU) could be the reason for this error.
Check the reasons in the first row, correct the error, and retry the operation. If the
error persists, try step 2.
Try the following procedures. If they do not work and the path is not restored, save
the HP disk array configuration information using
FD Dump and contact your
HP account support representative.
1. Verify that the cable between the local disk array and external disk array is
connected properly.
2. If the cable between the local disk array and external disk array is connected
properly, disconnect and reconnect it. After 30 seconds, check the path status
from Command View XP or XP Remote Web Console.
The status appearing in the
Ex-Dev. Status column is
Normal, but the status
appearing in the LDEV Status
is Unknown.
The LDEV’s status cannot be determined. This occurs when the LDEV does not
exist. The reason for the error could be:
• The LDEV was been created when the volume was mapped.
• The LDEV in the external LU was deleted by the Customized Volume function.
• If LDEV Status becomes Unknown by any reason other than above, contact
you HP account support representative.
