Problems Starting the System

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.

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.

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 name of the configuration group.

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.

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.)

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.
