There appars to be some conflation of lsscsi and lspci here lsscsi will show attached SCSI targets From the lsscsi -g output, it is showing two arrays, a tape drive, and a library changer, when the library is removed, it is expected that both the tape drive and the library will no longer show. To see if the HBA is detected, lspci is the command to run. The lspci command cannot tell you if a card will or will not work with a tape library, only if the card is detected, and what driver it is using. lspci -v might be more useful than -nn Any SAS HBA (as apposed to a RAID controller) _should_ work with any SAS Tape Library.
