Thanks for your hints,

i pulled the scsi-card out of the pci-slot and checked the  
termination, that looked okay. I checked the terminator at the changer  
itself which also looked okay. After that I installed the scsi-card  
and connected the cables.

I don't know if that helped. I rather guess the crucial thing was to  
*completely* power down the changer. Yesterday I only powered it down  
via the front panel but I guess that is only some sort of stand-by.  
Today I powered it down via a switch on the power supply. After  
powering on the changer and afterwards the computer everything looks  
fine:

boromir ~ # mtx -f /dev/sg4 status
   Storage Changer /dev/sg4:1 Drives, 8 Slots ( 0 Import/Export )
Data Transfer Element 0:Full (Storage Element 3 Loaded):VolumeTag = WOC4-03L4
       Storage Element 1:Full :VolumeTag=WOC4-01L4
       Storage Element 2:Full :VolumeTag=WOC4-02L4
       Storage Element 3:Empty
       Storage Element 4:Full :VolumeTag=WOC5-01L4
       Storage Element 5:Full :VolumeTag=WOC5-02L4
       Storage Element 6:Full :VolumeTag=WOC5-03L4
       Storage Element 7:Full :VolumeTag=WOC1-01L4
       Storage Element 8:Full :VolumeTag=WOC1-02L4

Thanks again to all of you. I appreciate your help very much.

Greetings
