D350 Hardware upgrade

I have an old HP 9000 D350 that is still running in production. We are upgrading the hardware on it this weekend but, I'm not 100% sure what to do. A third party vendor is going to come out and replace the parts but, since HP doesn't support the hardware or software (hp-ux 10.20) anymore, I'm kinda lost as to what to do after we boot it back up. I've never done a hardware upgrade before... just fresh installs and patching.

It currently has 1 100MHz processor and 128MB of ram. According to vendor, they are going to install a new mother board with 2 160Mhz processors, 1.5GB of ram and a new power supply (basically upgrading it to a D370). When I boot the box up, what do I need to do in order for the OS to recognize everything new?

Re: D350 Hardware upgrade

In your case, just replace the hardware. All pathes will remain the same (if you do all connections like the original). Just make sure the system will copy the serial number from the systemboard to the COU board (it will ask you, answer yes). Make a backup!

Hope this helps!

Re: D350 Hardware upgrade


Stephanie,

I have done this upgrade a couple times (although it was a couple of years ago)

There is no additional work more you as a sysadmin - all the system setting should remain the same.

The engineer doing the upgrade has to be careful (i.e. board placement and system serial number), but other than that is should go smoothly and relatively fast.

Re: D350 Hardware upgrade

One possible "gotcha" is that the MAC address of the built-in ethernet port has changed. It is not uncommon for software licenses to be tied to this value so that the license server now fails to verify your formerly valid codes.
If it ain't broke, I can fix that.

Re: D350 Hardware upgrade

BTW, AFAIR the systemboard will remain in the system, only the CPU board will be changed. In this case, the system will notice a difference between stored serialnuber in cpu and system-board. if I remember right in this case it doesn't ask and will just copy the value from the systemboard to the cpu board, but I'm not really sure.

Anyway, the upgrade should not be a problem.

If you increase the amount of RAM, you should increase the swap too. Either you restore an ignite backup and adjust the value while restoring or you add secondary swap (in this case also re-configure the dump device).

Hope this helps!

Torsten.

Re: D350 Hardware upgrade

This machine uses FDDI instead of ethernet. Is that going to cause an issue?

Re: D350 Hardware upgrade

All the time I talked about the serial number, but it is the MAC address!

The address is stored on the CPU and systemboard and will remain.

Hope this helps!

Re: D350 Hardware upgrade

I will explain this: Some software vendors will give you a licence to use their product on a certain machine. The software depends on the software ID (see man uname). The older systems calculate this value depending on the MAC address of the core I/O card stored in the system.

If the software ID is changed, the software won't run, because it's "thinking" this is another (not licenced) machine.

Hope this helps!

Torsten.

Re: D350 Hardware upgrade

In this case, it is the systemboard that will be changed and the MAC addreess will be different. I have even seen a case where the HP_ETHER_STATION_ADDRESS was set to the original board's MAC address and still the license wouldn't work. I was rather surprised that the explicit MAC address override wasn't recogized by the license server but I was never sufficiently curious to attempt to disassemble and analyze the code.

If it ain't broke, I can fix that.

Re: D350 Hardware upgrade

So, my question now would be... how do I fix it if the address is different and the software has fits because of it? The software hasn't been updated since the mid 90s. :)

Re: D350 Hardware upgrade

@ A. Clay:

There is only one type of systemboard for all D3xx systems. So the MAC address will remain (see my explanation). For SW ID the value from the board is used, not the "faked" one from the OS.

Hope this helps!

Torsten.

Re: D350 Hardware upgrade

This may not even be an issue -- it depends upon the existence of license servers and how they are implemented. Some only care about the IP address of lan0, for example -- and you would then be fine. The HP_ETHER_STATION_ADDRESS value in /etc/rc.config.d/hpetherconf may also be recogized by your license server. Your vendor (if still alive) may be able to generate new keys. Bear in mind that many UNIX software packages rely upon your honor and do no license checking, so all may be well as long as your upgraded machines conforms to the original license agreement.

The ultimate license "fix" may be to put everything back as it was.
If it ain't broke, I can fix that.

Re: D350 Hardware upgrade

Well, things did not go well. The 3rd party vendor sent 6 512MB modules. In order to get those to work, you have to update the pdc code... which you can't do anymore since hp doesn't supply it.

The only thing that got upgraded was the power supply. Now we are running into another issue:
The D350 boots from a Jamaica box thru SCSI connections. It doesn't boot. I get a "Warn A008" message and it won't go any further. We tried to seach for boot devices but, it just doesn't see them. We have rebooted the server and the jamaica box several times. Any suggestions?

Re: D350 Hardware upgrade

Try to upgrade again, use the small DIMMs and update the firmware:

ftp://ftp.itrc.hp.com/firmware_patches/hp/cpu/PF_CULU4211.frm

description:

ftp://ftp.itrc.hp.com/firmware_patches/hp/cpu/PF_CULU4211.txt

Are you sure you inserted all I/O cards and connected all cables to the original positions?

Hope this helps!

Torsten.

Re: D350 Hardware upgrade

Maybe the boot path was reset to default while you was upgrading the hardware. Try a "search ipl" at the boot prompt. It's important to cable the system exactly like before the upgrade.

Hope this helps!

Re: D350 Hardware upgrade

The tech didn't have the power plugged into the board correctly. We've gotten that fixed. We were having an issue with the boot path but, that has been fixed, too. Now, the issue we are having is that it is sitting at "INIT CEDF" and won't go past there. We've left it for about 1/2 an hour. Any more suggestions?

Re: D350 Hardware upgrade

It appears that the kernel does not recognize the new equipment. I know that the kernel needs to be rebuilt but, have no idea how to do this. In the past, I would always make some kind of kernel change and then rebuilt it but, don't know what needs to be changed now.

"It appears that the kernel does not recognize the new equipment" - Why do you think so?

Re: D350 Hardware upgrade

The kernel will not boot. And, after further research, I have found that the OS is 10.01 instead of 10.20. So, our only options are to max out the memory on the current motherboard (1536MB) or upgrade the OS to 10.20 to be able to upgrade the motherboard to one from a D370. Unless you guys can think of another option.

Re: D350 Hardware upgrade

I think to remember the kernel parameter swapmem_on have to be set to 1, but I don't know if this applies here. Just check it.
(remove the new CPU board, insert the old, boot and check).

Hope this helps!

Torsten.

Re: D350 Hardware upgrade

That kernel parameter is already set correctly. The problem seems to be that in order to upgrade this machine to a D370 (with the D370 motherboard), the OS level has to be at least 10.20.

Re: D350 Hardware upgrade

Maybe. Support end for all 10.xx was mid 2003 or earlier. HP-UX 10.01 was introduced 1995. Information about this is disappeared.

If you need the system for your business, you should consider to go with a new system with a supported OS version in preference to thinking about an update from 10.01 to 10.20.

At least consider to load HP-UX 11i v1 on the D370.

Hope this helps!

Torsten.

Re: D350 Hardware upgrade

If you refer to Torsten's respone above you can find the D350 firmware. I've pasted in the ftp link that should allow you to right click and 'save target as' or copy. Else, ftp to the site.

ftp://ftp.itrc.hp.com/firmware_patches/hp/cpu/PF_CULT3634.frm

This seems to be the latest firmware available for the D350, so your HW upgrade should be able to proceed.

If the issue continues you can upgrade to 42.11 ( see Torsten's response )and install HP-UX 11.00. See D370 compatiblity matrix link.

http://docs.hp.com/en/B3782-90726/ch02s02.html#d0e351

I've attached the 10.20 and 11.00 compatibility matrix. A D350 will support 32 bit HP-UX 11.00. So what level is your PDC firmware that it can't support 11.00?

Re: D350 Hardware upgrade

Michael Steele:

It is not the firmware that can't handle the upgrade, it's the application. It is a legacy app that is being "put out to pasture" as of April 07. They don't want to spend big $ on fixing the app so it can run on 11. The last time they looked at upgrading the hardware, OS and software... it was $250k. Since they are moving to SAP, this is not an option. They are trying to do this upgrade for under $5k. :) It sux to work on old systems.

Re: D350 Hardware upgrade

AFAIR, the D350 has PA7200 CPU 100 MHz max. mem 1532 MB, D370 has PA 8000 CPU 160 MHz max mem 3072 MB.

Beside different firmware and different CPU type (and power supply) the systems are very similar (even the same system board!). So IMHO an application cannot see *any* difference, it is just a bit "faster".

I did such kind of upgrades many times years ago and cannot see a reason why this should go wrong.

Hope this helps!
