multipath alias not being created.



(Apologies if this email gets double posted.  Wasn't sure if my other
address was subscribed to this too.)

Hey, I'm setting up a CentOS 5.5 box right now which uses a LUN from
our SAN.  Originally I had user_friendly_names enabled so I was using
/dev/mapper/mpath0 as the device name.  I want to change that to
reflect the LUN ID from the SAN so I disabled user_friendly_names and
set alias to LUN34.  I rebooted the box but I do not see
/dev/mapper/LUN34 and instead see /dev/mapper/<wwid>.  Does anyone see
what I'm missing?  I can't figure out what I'm missing.  I've read the
docs correctly and /dev/mapper/LUN34 should exist right?  Thanks.
