As the root user, try: echo 1 > /sys/class/scsi_device/device/rescan (Variations on that are covered at https://thornelabs.net/2012/08/22/linux-rescan-scsi-bus.html, which please also see.[1]) There is also a related script rescan-scsi-bus.sh traditionally said to be furnished by something called sg3_utils, which I have not seen.) (Disclaimer #1: The first tip worked long ages ago, but I've not tested it in a long time.) (Disclaimer #2: I am in a very different time zone where I am up a bit past my bed time, ergo not ideally situated to fact-check before trying to help. Sorry, good sir.) [1] Web-search on 'scsi rescan linux' if not yet getting anywhere. Could work. -- Cheers, "He who laughs last, lasts." Rick Moen -- Leo Rosten [email protected] McQ!
