Chapter 6 HPSS Configuration
408 September 2002 HPSS Installation Guide
Release 4.5, Revision 2
Device Name The name by which the
MVR can access the
device.
Any valid UNIX path name of a
device file.
None
Advice: This name is usually the path name of a device special file such as /dev/
rmt0/
For locally attached disk devices, the pathname should refer the raw/character
special file (e.g., /dev/rhpss_disk1).
For AIX systems, SCSI attached tape drives are typically referred to by pathnames
of the form /dev/rmtX, where X begins at zero and is incremented for each tape
drive detected.
For IRIX systems, SCSI attached tape drives are typically referred to by pathnames
of the form /dev/rmt/tpsXdYns, where X is the SCSI controller number, and Y is
the SCSI ID of the drive. Note that for Ampex DST drives, the tpsXdYnrns name
should be used (indicating that the driver should not attempt to rewind the drive
upon close). For other drives on IRIX, the tpsXdYnsvc name should be used
(indicating that the driver allow compression and variable block sizes).
For Solaris systems, SCSI attached tape drives are typically referred to by
pathnames of the form /dev/rmt/Xc, where X begins at zero and is incremented for
each tape drive detected (the ‘c’ indicates that compression is enabled). In
particular note that the device that contains a ‘b’ in the name should NOT be used,
as this will change the behavior of the drive which will cause the HPSS Mover to
fail.
For Linux systems, this is the name that will be used to provide access to the SCSI
raw device. The pathname will be in the form /dev/raw/rawX, where X specifies
the raw device number. You can run the “raw -q -a” command to determine the
correct raw device mappings. SCSI tape devices are referred to by pathnames of the
form /dev/stX, where X begins at zero and is incremented for each LUN detected.
