Adding in the new SCSI card

Leave a Comment / Bacula, FreeBSD, SCSI / By /

I’ve been building up a new server lately. Now I’m ready to move the tape library from the old host to thew new host. As I opened the new server to insert the existing SCSI card, I discovered that I needed a new SCSI card. It just would not fit. This is the card I was using under FreeBSD 8.4: ahc0: <Adaptec 2944 Ultra SCSI adapter> port 0xa800-0xa8ff mem 0xfb7df000-0xfb7dffff irq 20 at

Hardcoding device names

Leave a Comment / Backups, Bacula, Open Source, SCSI / By /

This article talks about FreeBSD 8.2 and how device names might change when you add new devices to an existing system. The other day, when I was telling you about the new tape library, one of the important bits was the device names. The existing tape drive was sa0. The new one was sa1. That’s good. But today, after a system reboot, the tape drives are renumbered. Here is what I had: Today,

Right after getting my SCSI cable problems fixed, I was all set to run some Bacula jobs. They immediately started failing: 27-Nov 12:59 bacula-dir JobId 112458: Start Copying JobId 112458, Job=CopyToTape-Diff.2012-11-27_12.58.05_08 27-Nov 12:59 bacula-dir JobId 112458: Using Device “DTL01” 27-Nov 12:59 kraken-sd JobId 112458: Ready to read from volume “DiffAuto-2357” on device “MegaFile” (/storage/compressed/bacula/volumes). 27-Nov 12:59 kraken-sd JobId 112458: 3301 Issuing autochanger “loaded? drive 0” command. 27-Nov 12:59 kraken-sd JobId 112458: 3991 Bad

It was the SCSI cable

Leave a Comment / Backups, Bacula, SCSI / By /

Last night I powered on my DEC tape library. I had forgotten to power it on earlier in the week after a maintenance session. Backups to tape were queueing up. Bits needed to be moved. Queues needed to be emptied. I powered on. I ran camcontrol rescan followed by camcontrol devlist. The tape library was not showing up. Did I manage to kill it? Did I unseat the SCSI card? After removing the
