HP DDS/DAT drives UNIX, Linux and OpenVMS configuration guide (DW049-90915, November 2009)

HP Evolution II DDS/DAT drives: UNIX, Linux and OpenVMS configuration guide 29
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:
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
st
Tape driver. Its presence shows the driver is loaded.
sym53c8xx
SCSI chipset driver for the LSI Logic family of HBAs (among others).
aic79xx
SCSI chipset driver for the Adaptec 79xx chipset family (such as Adaptec 29320).
