I am running debian squeeze

Server is Fujitsu TX140 with Controller Symbios Logic SAS1064ET PCI-Express Fusion-MPT SAS Tape+Hardware is new.

Right... you may just have a media problem or a hardware problem that offlines the device. — ewwhite, Oct 18 '12 at 17:17

For my SAS and SCSI-attached tape devices, I normally see the following modules loaded when I use MPT Fusion/LSI controllers:

[root@Lance ~]# lsmod  | grep mpt
mptctl                 31976  4 
mptspi                 17051  0 
mptscsih               36828  1 mptspi
mptbase                94037  3 mptctl,mptspi,mptscsih
scsi_transport_spi     26151  1 mptspi

Or...

[root@Doper ~]# lsmod  | grep mpt
mptctl                 74953  4 
mptscsih                2625  0 
mptsas                 26977  1 mptscsih
mptspi                 13521  1 mptscsih
mptscsi                50641  2 mptsas,mptspi
mptbase                78625  4 mptctl,mptsas,mptspi,mptscsi
scsi_mod              146193  9 sg,st,libata,cciss,mptsas,mptspi,mptscsi,usb_storage,sd_mod

Look at your setup and see if you have the same set of modules loaded.

Thanks. The Problem was fixed after using the cleaning Cartridge. Did not thought of that because Hardware is new. Helpful was [IBM Tape Device Drivers Installation and User's Guide](http://www-01.ibm.com/support/docview.wss?uid=ssg1S7002972&aid=1) — Tim Haegele, Oct 23 '12 at 21:35
