do the devices look something like /dev/sd*, or /dev/cciss/* or
something similar? if the later - it _could_ be a driver-specific issue,
and i would look for info about the specific block driver.

Is there a maximum number of paths supported by the device mapper ?
I have a setup with 12 paths to 14 luns. I had to reduce the number of
paths
to 10 for the device mapper to startup correctly.
i have seen such problems with linux kernel 2.4, long ago, when max SCSI
disk devices was 256 (and hence - also max paths for such devices).
if you're not using SCSI, but rather some other type of device - it
could be a limitation of the specific low level driver.
which kernel are you using? and which linux distribution? and what kind
of block devices do your disks reside on?
