That is, ChA has 3 disks + 1 tape, 2 of the disks are in a vinum volume, the third (and terminating) disk is "normal". IF the vinum volume is active (eg fsck) with the tape drive plugged in, the tape drive blinks, and the above messages come out... boot -s , and mounting the standalone disk only does NOT display any erros. kernel is SMP, os version is 3.1, i DONT have SCSI ID clashes :-), further info available on request after my 5gb at-a-time backup of the massive volume finishes :-)) Kiril To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
