Thanks for the fast response.
First, try the existing package with a product as well:
# grep -v ^# /etc/multipath.conf
blacklist {
devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*"
devnode "^hd[a-z][[0-9]*]"
devnode "^cciss!c[0-9]d[0-9]*[p[0-9]*]"
device {
vendor DELL
product "PERC H800"
}
}
# multipath -l -v 3
