startup setup of old K class server

Hi managers,

Someone knows how to configure the startup process of a K class server with OS: B.11.11 U 9000/899 (May be something like the OK prompt of a Sun server)

Hoping for your response

Re: startup setup of old K class server

You can interrupt the boot process at the "Press any key within 10 seconds" prompt and do some of your ISL configuration there.

What exactly are you trying to accomplish? What do you need to change?

Re: startup setup of old K class server

Currently the startup process takes almos 40 mins and makes a many memory tests, is there a way to make the startup process faster?

(May be I can not demand more of this old server)

Re: startup setup of old K class server

What exactly you want to configure?? The hp-ux server boot process is as follows.

pdc
isl
hp-ux
init+bcheckrc

On PDC prompt, you can server configuration, primary/alternate boot paths, memeory tests etc.

isl-initial system loader. If you interrupt (when it says press any key to interrupt boot process), you can interact with isl ,choose to load os as you want.

hp-ux is kernel. isl gives controll to hp-ux, which sets things up and calls init scripts. init scripts are /sbin/rc?.d depending upon ru level it is booting into or shutting down.

Re: startup setup of old K class server

You can turn on FASTBOOT. I can't recall exactly how this is done, but it is somewhere in the ISL menu you get when you interrupt the boot process. Just search through the menus until you find it.

This will speed things up slightly. But there is not a whole lot else you can do to speed up the boot process.

The K's are a slow booting server If your file systems are HFS, and not JFS, the boot time will be extended as well. Converting to JS will at least eliminate the startup fsck's

Re: startup setup of old K class server

It had been a while since I have touched a k-class but, if you interrupt the boot sequence, you will see one of the options as being "COnfiguration Options" select that one and one of the underlaying menus had an option saying fastboot enabled. You need to enable it if it is not. This will skip the memory tests at the boot time and I know they can tale a looong time.

Re: startup setup of old K class server

How much memory in the system? This will impact how fast the server boots as well.

Are there a number of applications to start? Each app that starts at boot will require time as well.

There is no OK prompt on HPUX. When you gracefully halt the system you get the message "It is safe to power off your system" - something to that effect. Power cycle the box and you start booting, unless you interact with ISL.

Re: startup setup of old K class server

Thanks all for your responses.

In solaris we can set values without restartin the server
e.g.

#eeprom diag-level=min ( as if you were at the ok prompt)

is something like this in HP-UX?

Re: startup setup of old K class server

You can interact with the GSP (Guardian Service Processor) and get similar info. Does not need to have the system rebooted.

This is the key sequence.

Do take care in this area since lots of settings affect how the system behaves.

Thanks Rick,

I wil try going to GSP

Thanks all again

Re: startup setup of old K class server

There is no GSP on the K-class computer. The only settings you can do with that box (while running HP-UX) is with the setboot command. Depending on how well your system is patched, setboot will have several options concerning boot primary/secondary, autoboot, and in some cases, selftest options that can be bypassed (known as SpeedyBoot).

Re: startup setup of old K class server

Hello, Alex. Yes, the K class is slow to boot, especially if you're fully loaded with memory and cpus. Some things for you to consider.

1. There is no GSP in the K Class. The GSP started in the N and L class servers. The K Class does have a Service Mode, enabled by turning the key on the front of the server all the way to the right and then doing the CTRL-B. There is NO configuration setting in the Service Mode that will help you do what you want to do.

2. When booting, and after the server has gone through it's normal Power On Self Tests, it will stop for 10 seconds at the BCH (Boot Control Handler) screen. Here you can hit any key to halt the autoboot processs. As stated in an earlier post, if you go in the CO (Configuration) menu, you will find FB (Fast Boot) option. Turning FB to ON will disable some of the testing done on memory when you boot.

3. Fast Boot should only be used if you are doing repeated boots, like when patching or tuning kernel parameters. Other than that you should leave FB set to OFF so that the server does the full testing on memory during a reboot. Should your server crash, you would want it to do a complete test on memory to help determine any problems.


I hope these help you out.

Good Luck - Tim

Alex,

Enabling fast boot will only skip some of the CPU tests and will not help much. Unfortunatly, with the K-class you just have to be patient. (Unless of course, you want to remove almost all the memory)

Re: startup setup of old K class server

I'm agree to all answers, don't use fastboot and allow the server to do some tests. It takes some time definitely. Just be patient or order a faster server ... ;-)

Hope this helps!
Regards
Torsten.

Re: startup setup of old K class server

Just to clarify about fastboot. It turns off the extended memory tests. All memory is always tested, but there are more exhaustive tests carried out when fastboot is not enabled. This can add several minutes per Gb of RAM. A 4Gb K460 will need almost 15mins to complete full selftests, about half that time if fastboot is turned on. It doesn't make too much sense to worry about fastboot if the server is running normally. You would want extensive diagnostics with new RAM or after an extended period of being powered off.

Re: startup setup of old K class server

Thanks all, Bill, Torsten, Brian, timmy, Mahesh,Rick, Mel, DCE, Rac, Patrick.

Indeed, I am not patching and tunning the server, therefore my reason to enable fast boot is to have the server up ASAP. But, taking your recommendations and points of view, I will take a decision, (may be new server, hehehe).

Thanks again guys,

Alex
