Description Mimmus 2007-10-09 14:49:32 UTC 
Description of problem:
Just after a reboot, this is the output of "multipath -ll":
mpath9 (360060160eb24170010eb64e5104adb11)

If I run "multipath -v2", I get:

 mpath13: map in use
(attached larger output of "multipath -v3")

multipath.conf

Default config file except for blacklist, where I put EMC controller wwid
Comment 4 Mimmus 2007-10-12 12:47:28 UTC 
Still no chance to get this working.
Only using "user_friendly_names no" seems to solve the problem.
Comment 5 Ben Marzinski 2007-10-12 18:16:11 UTC 
Can you please post your /var/lib/multipath/bindings file.  This is the file that
maps the WWIDs onto user_friendly_names.
Comment 6 Ben Marzinski 2007-10-26 22:35:46 UTC 
Without any more information, I'm going to assume that this the same problem as
bz #320151.  If This is incorrect, please reopen the bug.
