HP 9000/755 crash

[Adriana Gadbois]

755 will begin to boot, after finding the boot device and starting to boot, it halts for about 5 minutes, then a bunch of characters start to scroll up the display very quickly. here is what I could jot down....

Boot
:disk (2/0/7.6.0.0.0.0.0;0)/stand/vmunix
3880092 + 458752 + 1021728 start 0x1941e8

after that is displayed, that is when the computer halts for about 5 minutes with the LEDs lit as so:

SHOWN HIDDEN
0100 1111

Then the screen starts to scroll up very quickly with a bunch of characters that I can not read, when it stops, it displays:

I/O hardware probe timed out at path 2/0/1.0

also...

System Panic:
B2352B HP-UX (B.10.20) #1 : Sun Jun 9 (and a time)
panic:(display==0xbf00, flags==0x0)I/O System hung

also....

PC-Offset Stack Trace (read across....)
0x002261f4 0x001d3818 0x0012cb98 0x00203e54
0x000b602c 0x002060a0 0x000d7dc8 0x000d64d0

then....

Could not determine the cause of this crash.


Warning:Early dump not configured, *Contact your HP Support Representative.*

Warning:Can't initialize dump device
Dumpsys () failed, returned 4294967295



After that the system will start to try to boot again. It will keep repeating this sequence over and over.
Any help would be GREATLY appreciated!!!

Hi

the LED lights

0100 1111 indicate failed CPU.

The LED pattern on these systems starts on the top and works down. The code that was given actually means "Kernel is about to Configure IO system" which falls more in line with the problem you are having.

As stated you are having a with your IO system. In this case it is probably your disk drive. If you have another drive to boot up, or even an Install CD you can determine if this is the case. If the CD boots to the install program you can pretty much say that your disk is the culprit here. If you get the same problem with the CD then you are looking at a controller issue (system board), or perhaps cabling, but I doubt that.

Hi,

Check and see if you have the SCSI channels terminated properly. A hung I/O probe is most of the time related to a faulty terminator or a unterminated scsi channel.

Hope this helps.

ok, I swapped the drives with a known good 755, and it booted up normally, I also swapped the system board into the known good 755 and it booted up fine. when I brought the known good drives from the other 755 to the faulty 755, I still received the same indications. tried the known good cables from the other 755 in the faulty 755, same indications. Last thing I could think of is the disk frames. what do you think?
