All H/W are make sure no problem due to I had tested the tape drive working fine on below system after installed FreeBSD 9.

System spec.:

OS: SLES 11 sp2 or sp1
Server: Dell PE R200 w/ 2GB RAM
Dell 6Gbps SAS HBA (mpt2sas0)
Dell TL2000 SAS LTO5 tape auto-loader

Anybody has such experiences about it and has solution?
Is there any driver or package need to installed before get it work?
