[linux-lvm] unable to create physical volume

[rich turner <rich storix com>]

i am using 4 etherdrives that are block devices and present in the /dev
directory as:
brw-rw----  1 root root 152,  0 Nov  5 16:34 /dev/etherd/e0.0
brw-rw----  1 root root 152, 16 Nov  5 16:34 /dev/etherd/e0.1
brw-rw----  1 root root 152, 32 Nov  5 16:34 /dev/etherd/e0.2
brw-rw----  1 root root 152, 48 Nov  5 16:34 /dev/etherd/e0.3

when i try to create a physical volume out of one of them:
[root redhat proc]# pvcreate /dev/etherd/e0.1
  /dev/etherd/e0.1: Couldn't find device.

when i scan for available disks with "lvmdiskscan" these disks do not
display.

it looks like a filter problem within lvm.conf but i have made some
changes and it doesnt seem to work. these are the lines in my lvm.conf
file that i believe are responsible for finding block devices:
scan = [ "/dev" ]
filter = [ "a/.*/" ] (all other filters are commented out)

not sure if it helps but in /sys/block i can see entries like this:
[root redhat block]# ls -l /sys/block/etherd\!e0.0/
