[Bug 927540] [NEW] multipath ignores blacklist in multipath.conf

[gheeke]

Public bug reported:

Multipath in Ubuntu 12.04 ignores blacklist settings in multipath.conf

In multipath.conf the following blacklist is configured:


blacklist {
        wwid 36782bcb070070100166a7a1640a66db2
        devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*"
        devnode "^hd[a-z][[0-9]*]"
        devnode "^vd[a-z]"
        devnode "^cciss!c[0-9]d[0-9]*[p[0-9]*]"
        device {
                vendor "DELL*"
                product "PERC*"
        }
        device {
                vendor  "*"
                product "Universal Xport"
        }
        device {
                vendor  "*"
                product "MD3000"
        }
        device {
                vendor  "*"
                product "MD3000i"
        }
        device {
                vendor  "*"
                product "Virtual Disk"
        }
}

Still multipath -ll lists the internal SAS HDD (via Dell Perc 6/i
Controller):
