I have an HP ProLiant DL370 G6 server that I am using as a workstation. It takes 60 seconds during reboot and cold boot before screens post with a discrete Radeon HD6xxx GPU. What can I do to make it boot faster?

I have had a chance to use HP Gen8 server. It posts quickly and shows various CPU/memory/QPI initialization steps. Still takes a long time, but at least I can see what's going on.

FWIW, that's a crapload faster than the Dell M610, M700, and M710 blades that I was working with at my last job. – mfinni Dec 4 '12 at 3:15
@mfinni In other news: Dell's reliable memory technology is actually good for you. My question is about the specifics of HP server. I am curious to find out what takes that long, actually, and how to turn this thing off :) – GregC Dec 4 '12 at 14:29
That's why I posted a comment: I don't have an answer to your question :-) – mfinni Dec 4 '12 at 15:45
The Gen8 servers were modified to show early initialization steps on the console shortly after power-on. The boot and POST times are similar to the G7, but I suppose it gives people a warm-fuzzy to see something on the screen. – ewwhite Nov 1 '13 at 21:52
Yuppers. Warm fuzzies all around :) – GregC Nov 1 '13 at 21:59

There's no option here. Since the advent of the Nehalem and newer CPU's, the POST time on HP systems has grown tremendously.

I see that you're using this as a workstation. Is there any option to leave the system running and take advantage of some of the BIOS power management options?

For truth. They all take an extremely long time to POST. In an outage where minutes matter, it's rather annoying. – sysadmin1138 Dec 3 '12 at 21:05
It helps to disable option roms for network booting. – Matt Dec 3 '12 at 21:05
@Matt I am talking specifically about the time before screens post. Option ROMs for a myriad cards is a battle for another day. – GregC Dec 3 '12 at 21:06
@sysadmin1138 I'm about to send a G5 ML370 to another SF user. It boots in 60 seconds. The G6 variant of the same server is 90-110 seconds. – ewwhite Dec 3 '12 at 21:06

Nothing. HP's proliant servers simply are very slow at booting. G7 is even worse and G8 (just testing them now) hasn't improved things either. It looks shinier, but is slower still to boot.

Who needs fast boots? I just let the servers run until they die... # uptime 15:09:27 up 1033 days, 10:16, 39 users – ewwhite May 30 '13 at 22:09

Use kexec to reboot your server. This skips the pre-boot procedures entirely, and reboots into a Linux kernel at the end of the Linux shutdown process, rather than resetting the hardware and going to POST.

Unfortunately kexec is a bit cumbersome to use, so I wrote a script to make it easier to work with: kexec-reboot will allow you to choose a kernel from your grub boot list, or simply kexec the latest available kernel.

It's aiiiight. – ewwhite Mar 25 '15 at 11:44

My preferred solution to the horribly slow G8 bios boot time is to install the the free VMware vSphere Hypervisor instead of running the OS directly on the server.

Wut?!? That doesn't even make sense! – ewwhite Feb 13 '15 at 21:30
At some point, you'll have to patch and reboot the host running on the bare metal. Or you'll have a fault that causes same. Running ESXi instead of Windows or Linux won't change the boot time of the hardware. – mfinni Feb 13 '15 at 21:38
Say you reboot 100 times/year.. 90 are related to Windows Update, and 10 are related to Hardware maintenance.. Then you have a 90% faster boot time using a hypervisor. – moander Feb 14 '15 at 23:14
Having just spent a week debugging a Red Hat kickstart script that wasn't working as intended, this would have drastically reduced my work time. It wasn't the hardware that was faulty or needed patching, it was the Linux OS on top of that hardware. VMWare would make things so much easier. – shearn89 Feb 1 at 16:47
