Troubleshooting startup problems 14-17

System fails to start completely

Standard 1.0 Option 11 EC Installation and Maintenance Guide November 1999

Troubleshooting stage

1 or 2 startup failure

If the terminal output stopped at stage 1 after the message

“Time C tick OK” but before the message “Enabling

Instruction Cache,” or in stage 2 during the “BTGA tests...,”

follow these steps.

Troubleshooting stage

3 startup failure

If the startup fails during stage 3, it could indicate problems

with the SCSI subsystems. To proceed with a disk subsystem

check, follow these steps.

Troubleshooting stage

4 startup failure

If the startup fails at stage 4, it could indicate that the system

can initialize the SCSI disk but is unable to start from it. To

proceed, follow these steps.

Step Action

1 Replace the Enhanced MMP40 or MMP40 card.

2 Check for EC 11 power problems.

3 Verify that all cards are properly seated.

Step Action

1 Ensure that the correct Install/Data tape has been

inserted into the external tape drive.

2 Check the SCSI cable installation and all SCSI

addresses.

3 Ensure that the power supply is functioning correctly

by examining the status of the LEDs as described in

“Power supply description” on page 7-3.

4 If this is Node 2, replace the Enhanced MMP40 or

MMP40 card.

5 Replace the disk drive.

Step Action

1 Perform the checks in the previous (stage 3)

procedure.

2 Check that the disk drives do not have terminating

resistors.

3 Check that the tape drive is terminated properly.

There should be an external terminating resistor

pack, but no internal terminating resistor pack.
