I have no problems (knock on my wooden head for saying that!), and no
issues at the current time, but am sending this email so it will go into the
archives and perhaps help someone (maybe me LOL) in the future. I will use
lots of keywords below to assist in the search archive process.
Disclammer - I am not a writer. :-)
Getting Remote Console to work on DRAC cards on Dell PowerEdge servers.
1. Dell PowerEdge 750, FreeBSD 4.10 DRAC III/XT -plugged into slot 2 PCI
2. Dell PowerEdge 750, FreeBSD 5.4 DRAC III/XT -plugged into slot 2 PCI bus.
3. Dell PoweEdge 1850, FreeBSD 6.0 DRAC 4/I -plugged into internal dedicated
onboard DRAC slot.
No (local) keyboards plugged into the machines as they are all in cages at
Machines have DRACs connected to a dedicated port on WAN switch. static IPs
assigned, although they do have DHCP client abilities.
System BIOS correctly configured to allow DRAC to 'hook' into botting and
operating states. This setup slightly different between systems, but well
documented in the drac lit.
Server administrators should be able to connect to a dead (OS) system and
perform maintenance over IP when the system is powered up, or at least
No matter what we do it seems we can't connect to our Dell PowerEdge
Server's DRAC (Dell Remote Access Cards).
So much simpler than I originally anticipated.
On server 1 (Listed above):
I removed the flag in the kernel that instructed freebsd to disable the the
keyboard if there was not local one plugged in. ( it seems the DRAC (JAva)
console is not found until it is called by the browser).
Alos, ensure the kernel has AT Keyboard driver and device installed as the
XT (DRAC III) uses AT and not USB. The kernel conf now looks like # atkbdc0
controls both the keyboard and the PS/2 mouse
device atkbdc0 at isa? port IO_KBD
device atkbd0 at atkbdc? irq 1
device psm0 at atkbdc? irq 12
note the absence of the flag: flags="0x1"
The fix for FreeBSD 5.x is roughly the same, but the flag may have to be
removed from /boot/device.hints and the system rebooted.
In short, for the DRAC III need to ensure at keyboard is installed, and not
disabled when the boots without a keyboard connected.
On server 3:
dmesg showed in the broken state, the drac was trying to connect to a ugen
driver, it would then immediately disconnect. Someone mentioned that I
change what device and driver it connect to and as. see below.
Ensured that the USB (v1) drivers were installed. It seems that the system
bus supports USBII, but the card itself uses USB. So I added the options usb
to the mix in the kernel and recompiled. Worked like a charm. Disableing the
other USB drivers was not necessary.
Also, to ensure the console keyboard was connected to the USB keyboard on
the DRAC when connected to, I added the "unload atkbd" flag to device hints
(FBSD 6.0) hint.atkbd.0.flags="0x1", similoar to the flag that would be
added to pre6.0 in kernel conf.
I can;t definitively say that an extenal local USB or atkbd keyboard will
work since I have not had the oppertunity to test yet.
Server 2. Worked as is. not quite sure why yet. Although its config at
install time was almost identical to server 1.
