K220 will not boot

[Robert Bryan]

K220 server will not boot...
Receive error: Warn A008 (no boot device found)
I attempt to perform a "SEA" for bootable devices, but the search is terminated without displaying any error. The "IN" shows the pri boot path is OK...

The system board has been replaced and the PAL chip was transfered over no help...Need Help

[Robert Bryan]

I have removed all hard drives and attempted to run the SEA command again, no help. Removed all external devices from the server, no help.

Hi,

if the system cannot find a disk using "ser" or "ser ipl" command, there is a good change of having a failed drive.

Does the "search" command shows the other drives?

[A. Clay Stephenson]

The INformation can only tell you that the primary boot path is set correctly; it cannot tell you that the device is working.

I assume that you are trying to boot from one of the internal disks (I never did that on a K-box because the internal disks are not hot-plug); the HBA for the internal disks is located on the CORE I/O board. You either have a bad disk or a bad core i/o board or something as simple as a bad terminator.

[Patrick Wallek]

So do you have a valid boot device?

The error seems self explanatory. You need something to boot from.

If you removed all the hard drives, what do you expect to boot from?

[Robert Bryan]

The purpose of removing the drives was to eliminate anything from hanging the search...

The Server will not look for a bootable drive.

I have installed drives but receive the same error.

The drive I am trying to boot from is internal

[Robert Bryan]

LCD is also now showing 80F5 along with A008...When attempting to boot...If the boot process is interupted, that is when the SEA will not run...Without being able to search I dont know what the server thinks is installed as far as hard drives are concerned

[Robert Bryan]

LCD does show INIT C640 CPU 01 when the search is terminated...There are two CPU's in the system

You have an I/O error. Either the disk is bad, but since it does not show up in a search, the next most likely culprit is the SCSI card.

Dumb question - but it needs to be asked - If you have more than one disk on the internal channel are the SCSI adresses unique?

[Robert Bryan]

No SCSI card installed...Hard drive cage assembly plugs dirrectly into the system board...I believe the core I/O board performs all the work...The Core I/O board has been replaced (I have tried 3 different boards from know good systems.)I have also replaced the Hard drive cage 3 times and the cables once.

The drives all have different SCSI ID's.

[A. Clay Stephenson]

Here's a K-box manual that will preobably prove helpful.

Is the SCSI channel properly terminated?

[Robert Bryan]

I believe it to be...
There is one cable tha runs from the back card of the hard drive cage to the tape drive and CDrom and is then terminated... There is another cable that runs from the back card of the hard drive cage to the drives and is them terminated.
Both those cables have been replaced

[Steven E. Protter]

Shalom,

Its not going to boot any time soon.

Most likely the boot disk has gone bad.

The system has scsi cables and a drive cage, through which i/o and power is routed to internal disks. Any of this could be the problem.

If the system is really important you should pay time and materials to have HP hardware come and fix it. They probably can, in spite of the age of the box.

If it has a cd-rom, boot off the core OS and see what information you can gather on the system.

[A. Clay Stephenson]

You should note that the FWD SCSI cable that serves the internal hard drives has a terminator built-in but that same bus also has an external connection so if there is no terminator on the external FWD SCSI connector on the CORE I/O card then you have an unterminated SCSI bus. Because you are not detecting either the CR-ROM which is a separate SE-SCSI bus and you are not detecting any of the internal drives, (and since you have replaced the systemboard), I am leaning towards a bad Core I/O Card.

[Robert Bryan]

The hard drives have been replaced...

Tha main problem is the server is unable to perform a SEA... Without being able to search for bootable device I cannot boot from the CDrom.

What would cause a server to terminate a search for bootable devices?

My understanding is that the following components could cause the I/O problem
1. I/O Board (Replaced)
2. System Board (Replaced)
3. Hard drive Cage assembly (Replaced)
4. Hard drives (Replaced and
removed all together)
5. Cabling between the cage and hard dirves
(Replaced)

Is their something that I am missing

[A. Clay Stephenson]

If "I/O Board" means "Core I/O" then you have pretty much covered the bases except for a processor board. I assume that you have performed basic troubleshooting to make certain that all the voltages are within spec. The other thing is to determine exactly what "replace systemboard" means because if that was simply remove from one K-box and put it in another K-box then that is not sufficient. You also have to run SS_CONFIG to tell this systemboard among other things that it is indeed a K-220.

hi robert,

The most obvious thing to me which hasnt been mentioned yet is the local console?

what are these settings?

Check that scroll lock isnt on, if it is then this will terminate any search immediatley.

is it a HP terminal your using or?

Also a stuck key on the terminal keyboard would cause it to terminate
