Problems Starting the System
This section discusses how to identify system startup problems by reading
front panel lights and console displays.
The most important thing to do when you are starting the system is to
watch the console and front panel lights.
Generally speaking, messages are displayed fairly rapidly during all
phases of startup. This is normal. A long delay (more than 3 or 4
minutes) in the display of messages may indicate a problem.
Power-on problems
Your computer performs certain self-tests whenever the power is turned
on. A display similar to the following appears at the bottom of the
console:
OSTAT: XXXX REMOTE: aaa bbb ccc ACCESS FAULT: nn
____________________________________________________________________________________________________________________________________
* Does OSTAT appear as WARN or FLT?
FLT indicates a fault and usually prevents your system from coming
up. WARN is a warning that indicates that something is not quite
right, but it usually won't prevent your system from coming up.
If your system does not come up, write down both of the contents
of OSTAT and the four characters (XXXX) next to it. Try the steps
under "Clearing your system," in the following pages. If they
don't work, call your service representative.
For example:
FLT : 1F3A REMOTE: aaa bbb ccc ACCESS FAULT: nn
____________________________________________________________________________________________________________________________________
In this case, a fault has occurred (OSTAT field is FLT) and you
would record 1F3A and call your service representative.
* Note the color of the indicator lights on the computer front
panel. Is the orange indicator light on? Is the green indicator
light off?
This indicates a fault. Try the steps under "Clearing your
system," in the following pages. If they don't work, call your
service representative.
* Does your system appear locked? Does it seem like nothing is
happening?
This may also be a fault. Try the steps under "Clearing your
system," in the following pages. If they don't work, call your
service representative.
* If you see the following display:
_______________________________________
| |
| |
| booted... |
| |
_______________________________________
and nothing happens for 40 to 60 seconds, try the steps under
"Clearing your system," in the following pages. If they don't
work, call your service representative.
CAUTION Do not access the internal parts of either the computer or any
peripheral equipment. Do not remove the back panel of the
computer or any other device.
Initial system load problems
If your machine passes self-test it proceeds to ISL, or initial system
load.
During ISL many messages are displayed on the console screen.
* Has your machine stopped displaying messages and is the ISL>
prompt not displaying?
If your machine is successfully coming up, it should continue to
display messages at intervals of no longer than 2 or 3 minutes
(usually faster). If ISL successfully completes, you will see the
ISL> prompt. If you don't see the ISL> prompt and nothing else
appears to be happening, you may have a problem. Copy down the
last message displayed, try the steps under "Clearing your
system," in the following pages, and start your system again. If
the problem recurs, call your service representative.
Operating system boot problems
Operating system boot begins when you enter a START command at the ISL
prompt.
* Do you see any message indicating that a disk is not available for
mounting?
You may have used the wrong configuration file name in the START
command. Verify your configuration file or try a different one.
Shut down the system and bring it up again by entering the
following commands:
CTRL A
= SHUTDOWN Return
The shutdown process displays several messages. When shutdown is
complete ((SHUT 6) displays or 4 or 5 minutes pass and it appears
that nothing is happening), enter the following:
CTRL B
CM>RS Return
When you see the ISL> prompt, enter the following with the correct
file name:
ISL> START FILENAME NORECOVERY
Remember that FILENAME is the appropriate file name from table
4-1.
* Do you see the following message?:
___________________________________________________
| |
| |
| Error - Unable to get the SYSGEN version |
| or the version is obsolete |
| |
| status - subsys: #204 info: #-9051 |
| |
___________________________________________________
This message suggests that the configuration files shipped with
your machine have been changed. Call your service representative
for the correct files.
* Have you seen any error messages like the following?
_________________________________________________________
| |
| |
| 13:31/24/ DCC warning 103-5, |
| Add ldev to class failure (hlio status FF6A00BD) |
| |
| 13:31/18/ DCC STARTUP - ERROR |
| |
_________________________________________________________
If so and if you are booting for the first time with a new
configuration file, please ignore them.
Clearing your system
The following steps may clear a machine that appears to have faulted or
otherwise won't come up. After trying the following, begin your startup
procedure over again. If you still can't bring the system up, call your
service representative.
* Check all cable connections. Be sure that they are in the correct
place and are securely attached.
* Be sure that all external equipment is plugged in and turned on.
All device display windows should indicate READY or ONLINE.
* Power cycle your machine. (Turn the power switch OFF, wait 30 or
40 seconds, and turn it ON again.)
Problems with EZCONFIG
EZCONFIG is an interactive command file that performs certain
configuration-related tasks after your system has come up. Most EZCONFIG
error messages are self-explanatory and tell you exactly how to respond.
If you have correctly responded to EZCONFIG and still encounter problems
be sure to check the following:
* Is the number of disks that you specified to EZCONFIG different
from the number of disks for the configuration file that you used
in the START command?
Before you start your system, this manual asks you to determine
how many disks you have and to select a configuration file based
on this number. It is very important that the number of disks
that you specify to EZCONFIG is the same number that you used to
select a configuration file.
* Have you correctly specified your DTC addresses?
If there is any question about the correctness of your DTC
addresses, check them again, start EZCONFIG over again, and be
sure to specify the correct addresses.
CAUTION You may restart EZCONFIG at anytime during your initial setup
procedure; however, if you restart EZCONFIG after you have been
using the system for awhile and have established data on it, and
if you specify a different number of disks, you may encounter
problems in data storage and retrieval.
Never attempt to change your disk configuration(s) without first
making a full system backup. If you have any questions about
disk configuration and possible data loss, call your service
representative.
Problems with MKACCT
MKACCT is a command file that helps you establish user names, groups,
accounts, and passwords. If you have any problems with MKACCT, you may
restart it at any time without damaging your system.
MKACCT is interactive and, if you make a mistake, it prompts you for the
correct response.
You may verify the results of MKACCT with the LISTACCT, LISTGROUP and
LISTUSER commands. You may override anything accomplished by MKACCT with
the ALTUSER, ALTGROUP and ALTACCT commands. For more information on
these commands refer to Using Your System, or the MPE/iX Help Facility.
