The problem is that the netfinity 5100 shuts down without any message in the 
event log.
We have i/o errors on the library in the activity log (scsi adapter failure - 
we use adaptec 2944 UW and changed it three times).
 We 'd like to try without the multi-path, to have differents ids for the drive 
1 and the library manager. IBM is searching a solution for more than one year 
now, but they didn't try this.
Any suggestion is welcome.
