That's because the OS is being presented the logical drives on the RAID
arrays, rather than physical disks.

'ida' is related to the array controller drive--most modern Compaq
machines use 'cciss' instead. c0d0p1 is controller 0, logical drive 0,
partition 1.

Try adding:
ida/c?d?)
echo "$p CPQ_IDA_LD" >> $TMP
NUMHD=$[NUMHD+1]

The above should work--I've tested the code snippet I've suggested
against a machine with a similar configuration (except it's using the
cciss driver). I haven't tested a Knoppix install using this
modification, though, so you might hit other snags.
The one problem with my code snippet is that I don't bother to read the
model information from the drive. I don't know what Knoppix uses this
for, but the drives detected by my bit of code will have a model of
"CPQ_IDA_LD".
