[clue-tech] Compaq Armada 3500 woes

[Jim Ockers]

Hi Bill,

If you ever get a "/dev/sda: not found" type message, please do the 
following to see if it exists:

ls -al /dev/sda

If there is no device node for that device, you either need to mount the 
automagic /dev filesystem that will populate the directory based on the 
device drivers loaded into the kernel, or else consider creating it 
yourself.  IIRC sda is 8,0:

mknod /dev/sda b 8 0

If you can't write to the /dev directory, then create the device node in 
/tmp:

mknod /tmp/sda b 8 0

Then you can use your other commands such as grub-install to access that 
device.  The major & minor numbers on the device node "file" tell the 
kernel what device driver will handle the ioctl()s.  If the SCSI device 
driver chain is not loaded into the kernel then you wouldn't be able to 
access /dev/sda either, so make sure all the necessary driver modules 
are loaded if you have any trouble using a SCSI block device node.

HTH,
Jim
