Please feel free to direct me to the correct newgroup. I have a Dell 6650 running Suse Enterprise 8 (SLES8) with the 2.4.21-138-smp kernel. I have a Quantum M1500 tape library with 2 SDLT220 tape drives connected to one of the internal Adaptec Controllers using the aic7xxxx driver. One of the tape drives has failed. From experience, and from Quantum tech support, I know that turning off the library while the system is up will crash Linux. In searching the web, I've found the "remove-scsi-device" and "add-scsi-device" commands that can be sent to /proc/scsi/scsi. Does anybody know if the system will stay up if I use these commands to remove all my tape library devices before shutting it down? Is this the proper way to repair my library without having to shut the system off? TIA Eric Raskin PS. Dell wants to charge me $199 to get an answer to speak with the engineers who can answer this question. It's easier to just turn off the system! :-/ ---------------------------------------------------------------------------- Eric H. Raskin Voice: 914-765-0500 Professional Advertising Systems Inc.
