I have a Dell PowerVailt 120T DLT library, and want to see if I can get it to work with Amanda. When working up to setting up chg-zd-mtx, I seem to be having some weird issues:
If I cat /proc/scsi/scsi, here is my output: <snip> Attached devices: Host: scsi2 Channel: 00 Id: 01 Lun: 00 Vendor: ADIC Model: FastStor DLT Rev: D118 Type: Medium Changer ANSI SCSI revision: 02 Host: scsi2 Channel: 00 Id: 03 Lun: 00 Vendor: BNCHMARK Model: DLT1 Rev: 391B Type: Sequential-Access ANSI SCSI revision: 02 <snip> So it does see the loader device and the tape drive itself. If I run mtx inquirys against those devices, here's what I get: # mtx -f /dev/sga inquiry Product Type: Medium Changer Vendor ID: 'ADIC ' Product ID: 'FastStor DLT ' Revision: 'D118' Attached Changer: No # mtx -f /dev/sgb inquiry Product Type: Tape Drive Vendor ID: 'BNCHMARK' Product ID: 'DLT1 ' Revision: '391B' Attached Changer: No That looks good. So now, if I try loading a tape using " mtx -f /dev/sga load 1 " it works. But if I try unloading in the same fashion, I receive the " MOVE MEDIUM from Element Address 82 to 1 Failed " error. Which means I should use mt to rewind & eject the tape. Here's the results of using mt against those devices: # mt -f /dev/sga offline /dev/sga: Permission denied # mt -f /dev/sgb offline /dev/sgb: Permission denied Ok. It wasn't until I went to BRU's website that I found the following command (that worked): # mt -f /dev/nst0 offline Then I can finish up by issuing a " mtx -f /dev/sga unload 1 ". So, that explains what I've done... Now I was hoping someone could steer me in the right direction with chg-zd-mtx. It does support using the " mt <device> offline" but do I need to do anything special in my instance. And, is my instance unusual, or is the tape drive itself usually seen as /dev/nst0? Sorry for the longwinded e-mail. Nate D.
