Re: [Networker] device getting disabled

Also check the speed you can get on your tapes.
After enough SCSI errors Solaris will downgrade the SCSI speed - on the 
assumption that slower SCSI will have less errors, if the errors continue 
it will keep slowing the SCSI down until it ends up (I think) at < 
5Mbytes/sec and asychronous. The only way to bring the speed back up to 
what it should be is a reboot.
