5.3.3 Identifying the Error Path
Check the obtained path information to find the path with the error. In the Status
column, the error path has the status
Offline(E) or Online(E).
5.3.4 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.
5.3.5 Identifying the Error Location and Correcting any Hardware
Errors
Use the AIX and hardware management tools to identify the error location, and then
take appropriate, corrective action. For hardware maintenance, contact your hardware
vendor or maintenance company if there is a maintenance contract.
5.3.6 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
6.5 online (Places Paths Online). Execute the following command:
# /usr/DynamicLinkManager/bin/dlnkmgr 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.
