DLT Notes
DLT4000
The DLT 4000 micro code levels greater that 25 have a problem with the read position SCSI command. The release notes for the level 50 release claim that this problem is fixed. This is not correct, Quantum is still working on the problem. The ONLY release of the micro code that works correctly is level 25. If you are using DLT 4000 tape drives for SAM-FS, make sure the micro code level is at 25 or less.

DLT2000
For SAM-FS to use a DLT 2000 tape drive, the drive must be running a version of firmware that supports returning the capacity left on the tape currently mounted.

In order to determine if your DLT 2000 supports this feature, we have put together a tar file with the source and compiled binary to a C program that will function the drive and report the results.

You need to uncompress and un-tar the downloaded file, then run the getver program as root to determine if your DLT has the correct firmware level. If you have a C compiler, you can compile the source supplied in the tar file and execute that program instead. We have only tested it using Suns 3.0.1 C compiler.

See the comments section at the beginning of the getver.c program for more details.
