You have /dev/.static/dev/sg0. Is there also in that directory other sg#'s and st#'s? I'm unfamiliar with ubuntu's /dev/.static But the tape drive (you see it on sg0, and the changer mechanism, should appear as different devices. You earlier said your tape hardware was an HP 24x6. > Product ID: 'C1557A When I install this unit on Solaris or linux, the two devices come in as the same scsi id number, but different LUN's. # tapeinfo -f /dev/sg0 Product Type: Tape Drive Vendor ID: 'HP ' Product ID: 'C1557A ' Revision: 'U610' Attached Changer: No MinBlock:1 MaxBlock:16777215 SCSI ID: 5 <======= SCSI LUN: 0 <======= Ready: no # tapeinfo -f /dev/sg1 Product Type: Medium Changer Vendor ID: 'HP ' Product ID: 'C1557A ' Revision: 'U610' Attached Changer: No SCSI ID: 5 <======= SCSI LUN: 1 <======= Ready: no If your hardware or kernel is not scanning on boot for LUN's greater than 0, it may be missing the changer. This HP model has several configuration switches, some on the back panel and some internal (may require removal for access). Some of these have to be set to OS-specific settings (AIX, HP-UX, Solairs, Windows, ...) It made a big difference when I used that same unit on my Solaris system. If you don't have an installation manual, you might want to check HP's very good web support pages for the manual and look up what the settings should be for linux. Then confirm your device is correctly set. Then check your kernel settings (I'm not sure how to check this, but others will chime in) to be certain you are scanning for LUN's > 0. -- Jon H.
