Corrective action Error
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 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 XP Command
View Advanced Edi-
tion Software manage-
ment station or Re-
mote Web Console
cannot access the ex-
ternal LU.
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 external LU can-
not be mapped as an
internal LDEV of the
local array.
1. The errors listed in the first row of this table (Error: The XP Command View Advanced Edition Software
management station or 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 recon-
nect it. After 30 seconds, check the path status from XP Command View Advanced Edition Software
or Remote Web Console.
The path to the extern-
al LU is blocked.
