Bruce,
Why don't you just blacklist /dev/sda and /dev/sdb in /etc/multipath.conf?
That's what I do.
Alternatively, if you prefer to not blacklist by disk name, you can blacklist
by vendor and product.
Here's where I blacklist /dev/sda, /dev/sdb and any EMC or Compellent LUNs.
blacklist {
devnode "^sd[ab]$"
# AIK - reduce number of lookups on devices
devnode "^emcpower*"
device {
vendor "EMC"
product "*"
}
device {
vendor "DGC"
product "*"
}
# end AIK - reduce number of lookups on devices
}
For PERC LUNs, the vendor is "DELL" and the product varies, depending on PERC
model. For example "PERC H710" or "PERC H730P". But always seems to be "PERC*"

I'm having a problem with my MD3000i.
Every time I reboot, the Perc6e disk volumes are claimed by the multipath
driver and I get to fiddle to get the system back up. I suspect the problem is
in
linuxrdac-09.03.0C06.0452.2 as the readme says only kernel 2.6 is supported.
