I have some additional information that hopefully someone will be
familiar with and provide some assistance.

The kernel I am using 2.4.18-6 was created using devfs. However, when I
am trying to create a physical volume on /dev/hdb devfs is not active.
My /proc/partitions is as follows:

22   0      15972   hdc
 3   0   20066251   ide/host0/bus0/target0/lun0/disc
 3   1     313267   ide/host0/bus0/target0/lun0/part1
 3   2     265072   ide/host0/bus0/target0/lun0/part2
 3   3          1   ide/host0/bus0/target0/lun0/part3
 3   5    3076416   ide/host0/bus0/target0/lun0/part5
 3  64   20066251   ide/host0/bus0/target1/lun0/disc

is it the case that pvcreate is interpreting "disc" as a partition
because it does not detect a traditional "hdb" and therefore cannot
create the physical volume? is devfs required to be active for pvcreate
to locate the disc according to its naming convention?
