Dell 2970 - HP 1/8 G2 autoloader keeps falling off LSI 2032 SCSI chain
I’ve a somewhat irritating problem with a Dell 2970 that has a HP 1/8 G2 autoloader (the Ultrium LTO 2) attached to the LSI 2032 non-RAID SCSI card.
In essence, sometimes the autoloader/drive completely fails to appear on the SCSI chain (i.e.: there’s neither a media changer or tape drive within the device manager) sometimes it appears but then subsequently disappears at a seemingly random (yet always inconvenient) time, resulting in backup failures.
I’ve tried two different cables, both with the same effect – sometimes the autoloader appears (for a while), sometimes it’s completely absent. There’s only one terminator I’ve tried to use, but as I’ve since successfully tested the autoloader on multiple occasions (albeit via a Adaptec U160 card on a different machine), I’m fairly sure the issue doesn’t lie with this, or indeed the autoloader itself.
As such, I’m just wondering if anyone has any ideas?
It’s most likely not relevant, but this is all under Windows SBS 2008, running Backup Exec 12.5 SBS edition (the Dell version), both fully patched. Addidtionally, the autoloader is running the latest firmware.
It's been a while since I've dealt with anything SCSI, so all suggestions will be gratefully, gratefully received. :emotion-1:
Thanks in advance.

Hello JP,
The first thing that I would so is to run the Trace.exe inside the backup exe folder. What the trace program will do is to see if you are getting any extra SCSI commands that you shouldn’t be getting while the unit is not doing any backups. If you run trace and you see a bunch of Test Unit Ready entries then that is a sign that you will need to apply the tur fix. Here is a link to microsoft about the TUR fix which was really a bigger problem in win 2003 but has also been an issue in 2008 as well. support.microsoft.com/default.aspx
Let us know what your results are & we can look into the issue deeper.

Hi, Sam.
Thanks for the heads-up. I read about that tool in the Symantec troubleshooting guide, but it's not the sort of thing I fancy running on a production server during work hours, so I suspect I'll have to wait a while before I run it.
However, it's very useful to have something to aim for - I'll keep a look out for the "Test Unit Ready" entries.
