In my situation, I have a Promise 15100 raid with 2 logical drives configured on it. 1.6t and 1.8t respectively. Since these are different mounts, and I want to be able to back both of these up to one tape set, I've mounted them both into a single folder and then use gtar to back up that folder and it's contained slices. I'm finding that the Exabyte 221L, so far, works well with FreeBSD 5.3 (at least) provided the ch0 (library) is configured for either sequence1 (single drive mode) or scsi. In a single drive configuration, such as mine, if you wish to use the robotic arm in SCSI configuaration, mtx (from ports) is a good utility to help you with this library. There is one quirk about the 221L though that you need to be aware of, the mtx man page mentions it for the 220 but, well, we don't always read the entire man page. The 221L, like the 220, requires you to take the drive offline before performing tape move operations (mt offline). Once done, you can manipulate the tapes as needed. My current choice of utilities are: gnutar (available from ports, allows for shell script to run at the end of a multitape session) mtx (available in ports as a replacement to chio) You'll need to run a multitape session via gnutar and have it run a script at the end of a session (--new-volume-script). The script can be as complex or as simple as you need it to be. The basic script that I'm currently using is: #!/bin/sh /usr/bin/mt offline /usr/local/sbin/mtx next This takes the drive offline, ejecting the tape, uses mtx to place current tape back in source slot then move to the next tape in series to the drive, loads it and exits. Then gtar will continue on it's mery little way until it reaches the end of tape again. I'd like to thank those members of these 2 lists that replied both on and off list for their assistance in this. -- Micheal Patterson Senior Communications Systems Engineer TSG Incorporated 405-917-0600 Confidentiality Notice: This e-mail message, including any attachments, is for the sole use of the intended recipient(s) and may contain confidential and privileged information.
