We have a sun v480 server running legato networker backup and whenever we 
reboot the server the scsi dev changes from [email protected] to [email protected]. 
this started a month back when the server started rebooting randomly. The scsi 
dev is seen when we issue the inquire command from legato. It has been working 
fine from past 3 years until the recent abnormal reboots. If we run EMCGrab on 
the host it sets the scsidev back to [email protected].
