The machine is an HP DL380G5 with an HP smart array P400i raid 
controller. I was just testing the multipath support because I will need 
it later on. The RAID disk is not available using multiple paths, but 
multipath should still list it as one path (IMHO).

With the default blacklist info and the patch checker configured for 
LOGICAL VOLUME devices, the callout still fails, because it checks for 
/dev/cciss!c0d0 instead of /dev/cciss/c0d0:

When I run it manually with the correct path, it works:

tigris:~# /lib/udev/scsi_id -g -u -d /dev/cciss/c0d0
3600508b100104d395357463047410001

With the regular expression as I suggested it in multipath.conf, the 
device is blacklisted:

tigris:~# multipath -v3
ram0: device node name blacklisted
ram1: device node name blacklisted
ram2: device node name blacklisted
