The tape drive works. Today, after a successful backup with dump, I inserted a new tape, and any attempts to write data to the drive produced only this: (sa0:ncr0:0:6:0): WRITE(06). CDB: a 0 0 28 0 0 (sa0:ncr0:0:6:0): ILLEGAL REQUEST csi:0,8,0,0 A read attempt didn't fare any better: (sa0:ncr0:0:6:0): READ(06). CDB: 8 0 1 0 0 0 (sa0:ncr0:0:6:0): ILLEGAL REQUEST csi:0,8,0,0 # camcontrol reset 0:6:0 Reset of 0:6:0 returned error 0x6 And the problem persisted. Removing and reinserting the tape or another tape didn't help either. Rebooting did. :-( (Damn. For ten years SCSI has been pretty much plug and play for me. But ever since I put that tape drive into the FreeBSD box I get the impression I should have a copy of the SCSI specs on my desk.) -- Christian "naddy" Weisgerber naddy@mips.rhein-neckar.de carpe librum: books 'n' reviews To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
