I cannot access the raid device with fdisk: "Unable to read
/dev/mapper/hpt37x_fjfegdadi".

I have two identical hard drives. They have empty partition tables.
# dmraid -r
/dev/hde: hpt37x, "hpt37x_fjfegdadi", stripe, ok, 120064832 sectors, data@ 0
/dev/hdg: hpt37x, "hpt37x_fjfegdadi", stripe, ok, 120064822 sectors,
data@ 10
# ls -l /dev/mapper/
total 0
crw------- 1 root root 10, 63 Oct 25 11:55 control
# dmraid -ay
ERROR: dos: reading /dev/mapper/hpt37x_fjfegdadi[No such file or directory]
# ls -l /dev/mapper/
total 0
crw------- 1 root root  10, 63 Oct 25 11:55 control
brw-rw---- 1 root disk 253,  0 Oct 26 02:07 hpt37x_fjfegdadi
# fdisk /dev/mapper/hpt37x_fjfegdadi

Unable to read /dev/mapper/hpt37x_fjfegdadi

What's my problem? Why can't I access the raid device?
Just to be thorough I tried this with identical filled partition tables
as well -- no joy.

TIA
Duane
