sorry, I've missed that before. /dev/sdc is only _one_ of your paths to
a LUN. multipath will take the right 2 of those sd* to create one dm
device file. Have a look if there's somethign in /dev/mapper, also check
your udev rules, you need this line in there:
KERNEL=="dm-[0-9]*", PROGRAM="/sbin/devmap_name %M %m", NAME="%k",
SYMLINK="%c"
most distros have a line like
#KERNEL=="dm-[0-9]*", NAME=""
in there, you need to comment it out if you add the lien above.
Hope that helped,
best regards
Bernd Zeimetz
