pathinfo.txt
is the redirection-output file name. Use a file name that matches your
environment.
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 Windows and hardware management tools to identify the error location, and
then resolve the problem. If an error occurs in a path, HDLM will output an error
message to the host event log. Information about the path in which the error has
occurred is also output to the event log. 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:
>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.
Notes:
If path errors occur on all of the paths, and Windows recognizes some or all of the
paths, disk numbers might be changed over from the ones that were being used
before. If this happens, restarting the host will cause the disk numbers to be
returned to their original values. After the disk numbers have changed back, use
Symantec Backup Exec for Windows or the Intelligent Disaster Recovery
function of Veritas NetBackup.
