You can use this procedure to find information about a
problem with your server hardware that is running the IBM® i operating system.
If you experience a problem with your system or logical partition,
try to gather more information about the problem to either solve it,
or to help your next level of support or your hardware service provider
to solve it more quickly and accurately.
This procedure refers to the IBM i control language (CL)
commands that provide a flexible means of entering commands on the IBM i logical partition or
system. You can use CL commands to control most of the IBM i functions by entering
them from either the character-based interface or System i® Navigator. While the CL commands
might be unfamiliar at first, the commands follow a consistent syntax,
and IBM i includes
many features to help you use them easily. The Programming navigation
category in the IBM i Information Center includes a
complete CL reference and a CL Finder to look up specific CL commands.
Remember the following points while troubleshooting problems: - Has an external power outage or momentary power loss occurred?
- Has the hardware configuration changed?
- Has system software been added?
- Have any new programs or program updates (including PTFs) been
installed recently?
To make sure that your IBM software
has been correctly installed, use the Check Product Option (CHKPRDOPT)
command.
- Have any system values changed?
- Has any system tuning been done?
After reviewing these considerations, follow these steps:
- Is the IBM i operating
system up and running?
- If you have a management console,
ensure that you performed the steps in Beginning problem analysis, and then
return here if you are directed to do so.
- Are you troubleshooting a problem related to the System i integration
with BladeCenter® and System x® within an
internet small computer system interface (iSCSI) environment?
- Are you experiencing problems with the Operations Console?
- The reference code description might provide information or an
action that you can take to correct the failure.
| Go to the Reference code finder and type the reference code
in the field provided. Read the reference code description and return
here. Do not take any other action at this time. Was there a reference
code description that enabled you to resolve the problem?
|
- Yes: This ends the procedure.
- No: Continue with the next step.
|
- Does the console show a Main Storage Dump Manager display?
- Is the console that was in use when the problem occurred (or
any console) operational?
Note: The console is operational if a
sign-on display or a command line is present. If another console is
operational, use it to resolve the problem.
- Yes: Continue with the next step.
- No: Choose from the following options:
|
- Is a message related to this problem shown on the console?
- Yes: Continue with the next step.
- No: Go to step 13.
|
- Is this a system operator message?
Note: It is a system operator
message if the display indicates that the message is in the QSYSOPR
message queue. Critical messages can be found in the QSYSMSG message
queue. For more information, see the
Create message queue QSYSMSG
for severe messages topic in the Troubleshooting navigation category
of the
IBM i Information Center.
- Yes: Continue with the next step.
- No: Go to step 11.
|
- Is the system operator message highlighted, or does it have an
asterisk (*) next to it?
- Yes: Go to step 20.
- No: Go to step 15.
|
- Move the cursor to
the message line and press F1 (Help). Does the Additional Message
Information display appear?
- Yes: Continue with the next step.
- No: Go to step 13.
|
- Record the additional message information on the appropriate
problem reporting form. For details, see Problem reporting form.
Follow the recovery instructions
on the Additional Message Information display.
Did this solve
the problem? - Yes: This ends the procedure.
- No: Continue with the next step.
|
- To display system
operator messages, type dspmsg qsysopr on any
command line and then press Enter.
Did you find a message that
is highlighted or has an asterisk (*) next to it? - Yes: Go to step 20.
- No: Continue with the next step.
Note: The message monitor in System i Navigator can also inform you
when a problem has developed. For details, see the Scenario: Message
monitor topic in the Systems Management navigation category of
the IBM i Information Center.
|
- Did you find a message with a date or time that is at or near
the time the problem occurred?
Note: Move the cursor to the message
line and press F1 (Help) to determine the time a message occurred.
If the problem is shown to affect only one console, you might be able
to use information from the JOB menu to diagnose and solve the problem.
To find this menu, type GO JOB and press Enter on
any command line.
- Yes: Continue with the next step.
- No: Go to step 17.
|
- Perform the following
steps:
- Move the cursor to the message line and press F1 (Help) to display
additional information about the message.
- Record the additional message information on the appropriate problem
reporting form. For details, see Problem reporting form.
- Follow any recovery instructions that are shown.
Did this solve the problem?
|
- Yes: This ends the procedure.
- No: Continue with the next step.
|
- Did the message information indicate to look for additional messages
in the system operator message queue (QSYSOPR)?
- Yes: Press F12 (Cancel) to return to the list of messages
and look for other related messages. Then return to step 13.
- No: Continue with the next step.
|
- Do you know which
input/output device is causing the problem?
- Yes: Continue with step 19.
- No: Continue with the next step.
|
- If you do not know which input/output device is causing the problem,
describe the problems that you have observed by performing the following
steps:
- Type GO USERHELP on any command line and
then press Enter.
- Select option 10 (Save information to help resolve a problem).
- Type a brief description of the problem and then press Enter.
If you specify the default Y in the Enter notes about problem field,
you can enter more text to describe your problem.
- Report the problem to your hardware service provider.
|
|
- Perform the following steps:
- Type ANZPRB on the command line and then press Enter.
For details, see Using the Analyze Problem (ANZPRB) command in
the Troubleshooting navigation category in the IBM i Information Center.
- Contact your next level of support. This ends the procedure.
Note: To describe your problem in greater detail, see Using
the Analyze Problem (ANZPRB) command in the Troubleshooting navigation
category in the IBM i Information Center. This command
also can run a test to further isolate the problem.
|
- Perform the following
steps:
- Choose from the following
options:
- If there are reference codes appearing on the control panel or
the management console, record
them. Then go to the Reference codes to see if there are additional
details available for the code you received.
- If there are no reference codes appearing on the control panel
or the management console, there
should be a serviceable event indicated by a message in the problem
log. Use the WRKPRB command. For details, see Using
the Work with Problems (WRKPRB) command.
