6 Linux (kernel 2.6.x) servers and workstations NOTE: USB, SCSI and SAS drives are supported on Linux kernel 2.6.x. Determining the SCSI ID Look at the output of dmesg to find out what SCSI channel number is used for each connection. To find out the SCSI IDs in use on each channel, type: cat /proc/scsi/scsi This will produce output similar to the following for each device: Attached Devices Host: SCSI0 Channel: 00 Id:00 Lun:00 Vendor: HP Model -----------Type: Direct-Access ANSI SCSI Revision 02 Look at the ID information to establish which IDs are in use. Configuring on Linux systems No changes are needed to support DDS-format drives on Linux platforms, however you should ensure that you have the relevant drivers loaded. To see the device drivers loaded currently, execute an lsmod command, this will give output like: Module Size Used by sgm 4376 1 ide-scsi 7200 0 lockd 30792 1 sunrpc 53316 1 st 24656 0 sym53c8xx 39696 1 aic79xx 186044 3 scsi_mod 100408 5 [ide-scsi st aic79xx mptscsih] The lines of interest here are: st sym53c8xx aic79xx Tape driver. Its presence shows the driver is loaded. SCSI chipset driver for the LSI Logic family of HBAs (among others). SCSI chipset driver for the Adaptec 79xx chipset family (such as Adaptec 29320). Latest SCSI and SAS controller drivers for Linux will be available from the manufacturer's web site. In order to communicate with a tape device, the operating system needs to have drivers for the tape and the underlying transport mechanism (the host bus adaptor) loaded. Ensure that both are HP Evolution II DDS/DAT drives: UNIX, Linux and OpenVMS configuration guide 29
