Hi All,
I've been using multipathing a solid 6 months now in a couple of
(18) node production 10g clusters. What I'm tasked with right now, is
deporting about 30 luns or so from one of the clusters for recycling,
and before we remove the luns from the SAN side of things, I want to
blacklist them from the device-mapper, and then remove them from the
OS. Problem is now, I can't get the blacklisting to work for me.
Have any of you out there been able to blacklist fiber luns via the
UID of the lun? As it stands, I'm trying with a configuration that
looks like this:
devnode_blacklist {
wwid 3600096a1303030343030303030383262
devnode "^(dm-|fd|loop|md|ram|raw|scd|sr|st|sda) [0-9]*"
devnode "^hd[a-z] [0-9]*"
devnode sda # internal disk
}
Being that I've never done this before, Is it safe to assume that if
in fact it was working, that the UID(or wwid) of that lun, would no
longer be present in the /dev/mapper/ directory? If i'm overthinking
things here, or just plain old missing something, I'd appreciate a
little guidance.
Thanks In Advance,
Mike Kershaw
