HP XP7 Storage - Manual (Page 90)

Narrowing Down the Hardware That Might Have Caused the Error
Check the DskName, iLU, ChaPort, and HBAPortWWN columns of the path with
the error to narrow down the hardware that may be the cause of the error.
To physically identify the hardware corresponding to DskName, iLU, and
ChaPort, use the information provided by the storage-system management
program.
Identifying the Error Location and Correcting any Hardware Error
Use the VMware vSphere and hardware management tools to identify the
error location, and then resolve the problem. For hardware maintenance,
contact your hardware vendor or maintenance company, if there is a
maintenance contract.
Placing the Path Online
After the path has recovered from the error, use the dlnkmgr command's
online operation to place the path back online. For details on the online
operation, see online (Places Paths Online) on page 6-11 .
Execute the following command from the remote management client:
dlnkmgr -s host-name -u user-name -p password online
Executing this command places all the offline paths online.
If any path cannot be placed online due to an error, the KAPL01039-W
message will appear. To ignore such paths and to continue processing, type
y. Type n to cancel processing.
Check the statuses of the paths that cannot be placed online, and resolve the
problem.
