RE: cacti/nagios monitoring.

www.nagiosexchange.org has heaps of great plugins for dell servers. I'm
using them to monitor server health and raid arrays on both windows and
linux.

RE: cacti/nagios monitoring.

I wrote some Nagios health checks that use NRPE to check on the PERC4
controllers using amr(4) on FreeBSD and the megarc(8) util.

I also wrote some utils for MRTG that return IPMI values using the
impitool(1) "SDR Cache" feature.

I plan to release soon.

How do I update the BIOS on a linux server without a floppy?

Well, as they say, the road goes on forever and the party never ends.

 

I need to update the bios on my PowerApp servers.  However, the BIOS update utility:

 

http://ftp.us.dell.com/bios/B103RE06.exe

 

wants to create a floppy on A: from within a DOS shell.  My present workstations have no floppy disks (only CD/DVD), and the PowerApp servers are running linux.

 

Is it possible to upgrade the bios of a linux machine from CD, or perhaps over the network?

 

Thanks much,

… watchman

Console Redirection After Boot

All:

What's the deal with this feature?  Was it intended to be used for any
relatively modern OS? 

It seems to work with DOS and Memtest86+, and perhaps then even some of
the bootable FreeDOS based utils available from Dell.

But forget about using it for anything that "does not use the BIOS for
console I/O."

All the Dell Linux docs I find suggest not using it; use the DRAC
VGA->VNC feature instead,  but Dell really bungled that with the new
DRAC5 and the ActiveX dependency (imagine that, an embedded Linux device
that serves an ActiveX applet -- the irony is painful)

Firefox 1.0.x and DRAC5

Has anyone successfully used the Console Redirection or Remote Media
extension in the new DRAC5 with Mozilla Firefox 1.0.x ?

At first I assumed that the DRAC5 docs only listed FF 1.0.5 as
"supported" because of Redhat ES/AS bitrot, but I recently tried FF
1.0.8 on Win32 and neither Media or Console are functional, which leads
me to doubt that they're functional in RHEL on 1.0.5_[some_patch_level].

I mean, how hard can it be to teach the JRE to read /dev/floppy and
/dev/cdrom on the host?   Why does this stuff have to be ActiveX?

And the VNC Remote Console Redirection on DRAC4 was perfect; the latest
patch fixed a couple of longstanding bugs that involved key sequence
recognition.

Such a shame....

Not sure, but I can offer an alternative solution :)

I've get a USB floppy drive that I use to do such things on floppy-less 
machines. As long as the BIOS will let you boot from USB devices it 
works a treat.

Cheers,
Dave

There are 1850s with dual-core processors.

RE: How do I update the BIOS on a linux server without a floppy?


Harald wrote a nice tip on that a while ago. It is as follows:

To set up GRUB to allow a user to boot a floppy image:

1. Copy the floppy image to /boot
2. Copy the memdisk file, usually it is in /usr/lib/syslinux, to /boot
3. Edit your GRUB config, add something like:
	title Firmware/BIOS Update
     		kernel /memdisk
		initrd /<imagename>.img
4. At boot select the "Firmware/BIOS Update".

I can't answer your question about using BIOS for console IO, so this may
not help, but I do use "console over serial" in many (remote) Linux
installations I have (None Dell, but I see no reason why it won't work in
a Dell). You can make lilo use the serial line (and I'm sure grub too),
and it's a compile & command-line feature for the linux kernel (but I'd be
surprised it if wasn't included in the standard Dell/RH kernels, and you
just needed to activate it somehow - eg. in the grub config file)

In lilo.conf it's as simple as putting:

  serial=0,57600n8

in it somewhere, and to make linux use it, you need something like:

  append="console=ttyS0,57600n8"

in the same file. I'm sure grub does it in a similar fashion, but I don't
use grub so can't comment there. I do it this way on another vendors mobos
which have a BIOS over serial switch, so if required I can connect to a
servers serial line (cisco terminal concentrator thingy) power cycle it,
and from then on, do bios "stuff", then boot lilo and do lilo poking, then
into linux (with extra command-line "stuff", if required, and it all "just
works".

There is also a comple-time version of memtest to make it work over a
serial-line too (rather than rely on the console redirection, I guess)
I've used this too (but also have the non-serial line version of
memtest86+ installed too!)

Install OpenManage but not the webserver if you don't want to run that, 
first though make sure snmp is installed. Then there are scripts to 
check chassis status and raid status on nagios exchange. For the 
trending data there are scripts available to punt this info into cacti 
so you can trend temps and fan speeds etc.

I do all this and it works great.
