Booting a root drive with different server

[Dennis Trice]

I have a K450 server with the root drive on EMC. When I try to replace the server with a another K450 and boot from the EMC I can't boot. The firmware rev is different, could that be the problem?

Depending on how the EMC connects to the K, the PDC (firmware) of the K could very well be your problem.
You do not say how it is connected or the OS revision. Also, what is the Firmware version of the Kclass system,?

[Dennis Trice]

It connects through the Scsi channel on the core IO. I'm running 10.20 and the firmware thats on there is 38.xx and the newserver i'm having trouble with has PDC firmware rev of 39.12

This is similar to the case when you are having a CPU upgrade. You would need to request for HP Engineer to set the CPU-ID of the new server using a utility call SS_CONFIG to be the same as the CPU-ID of your old server.

There is no need to change the system ID with SS_Config.
It's strange that the server with 39.12 does the problems, so it is no PDC issue.
Which SCSI host bus adapter on the core IO do you use? The optional HSC card?
I'm asking that question, because I assume it's a problem with termination or cables.

[melvyn burnard]

Interesting!
When you attempt to boot the new server, if you interrupt the auto boot, can you see the boot disk by doing a search for bootable devices?
I assume the SCSI cable is the same one that connects to the working node, i.e. you just move the cable across?
Could be the SCSI card, termination.

[Dennis Trice]

If I interupt the boot process. I can search the drives, but when I search for ipl then it doesn't find anything. I don't think its the terminator because termination is the same as the old server.

[Patrick Wessel]

I doubt that we deal with a PDC issue. I assume it's a SCSI bus related
The SCSI bus is terminated on bot ends. One on the EMC box, the other one on the SCSI host bus adapter. This is, why I asked you about the SCSI interface in the Server. You didn't move the whole Core IO, did you?

Where was the EMC connected to on the first system (where it was working) and which SCSI connect do you use now? Do you use terminating cables?
