If you have a problem with the Command View XP computer or Command View XP or XP Remote
Web Console software, see the HP StorageWorks Command View XP user guide for XP Disk Arrays or
the HP StorageWorks XP Remote Web Console for XP12000/XP10000/SVS200 for troubleshooting
information.
For additional assistance, contact your HP account support representative.

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.
Thereasonfortheerrorcouldbeoneofthefollowing:
• 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 array changed, and the external LU was
deleted.
• An error occurred with the external LU in the external array.
• The path in the external array changed.
• The port attribute of the local array is no longer external.
• The topology information is not set correctly.
The external LU cannot be
mapped as an internal
LDEV of the local 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/SVS200) available for the local
array.
• There are not enough CU:LDEV numbers available for external LU mapping.
The path to the external
LU is blocked.
1. The errors listed in the first row of this table (Error: The Command View XP
management station 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 2b.
2. Try the following procedures. If they do not work and the path is not restored,
contact your HP account support representative.
a. Verify that the cable between the local array and external array is
connected properly.
b. If the cable between the local array and external 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.
TheLDEV'sstatuscannotbedetermined.ThisoccurswhentheLDEVdoesnot
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 Volume Manager function.
If LDEV Status becomes Unknown by any reason other than above, contact you
HP account support representative.
