multipath-tools recommends no packages.

Versions of packages multipath-tools suggests:
pn  multipath-tools-boot  <none>

-- no debconf information

The multipath.conf was only a try to isolate the error. Normaly I don't have 
this file and it can removed.

All devices on external FC-RAID which have partitions no get a mapper-path and 
fails with message in syslog:

In this way lvms having one or more pvs on such device can't mount.

Ultimatly I add oldstable and pining multipath-tools and lvm2 on this and now 
the system works (after 7 hours searching for solution).
Maybe the problem is in conjuction with the lvm2-package. Only downgrade 
multipath-tools not solve the problem and only downgrade lvm2 too.

with regards
