The program stinit is meant for initializing of SCSI tape drive modes
|
||
at system startup, when the tape driver module is loaded, or when new
|
||
tape drivers are initialized using
|
||
echo "scsi add-single-device x y z v" >/proc/scsi/scsi
|
||
or (with 2.6 kernels)
|
||
echo "y z v" > /sys/class/scsi_host/hostx/scan
|
||
where x=host y=channel z=id v=lun (- is wild card for 2.6).
|
||
|
||
The parameters used in initialization of a tape drive are fetched from
|
||
a text file. The parameter file is indexed by the inquiry data
|
||
returned by the drive, i.e., the parameters are defined by the drive
|
||
manufacturer, model, etc. This means that the initialization for a
|
||
drive does not depend on its hardware address. A similar method is
|
||
used by most Unices either within the kernel or outside the kernel.
|
||
|
||
The contents of the configuration file and the command line parameters
|
||
are defined in the man page stinit.8. A sample configuration file
|
||
stinit.def.examples is included in this distribution. It can be used as
|
||
example when writing descriptions for the tape drives in a
|
||
system. NOTE that the examples by no means specify what are the
|
||
"correct" parameters for different types of devices.
|
||
|
||
The program is configured for maximum of 32 tapes and 4 modes (the
|
||
default Linux configuration). If the kernel is configured for
|
||
different number of tape modes, the definitions MAX_TAPES and
|
||
NBR_MODES in stinit.c should be configured accordingly. (With 8 bit
|
||
minor numbers NBR_MODES * MAX_TAPES == 128.)
|
||
|
||
The files:
|
||
stinit.c - the program source code
|
||
stinit.8 - the man page
|
||
stinit.def.examples - a file containing example definitions for
|
||
imaginary tape drives
|
||
Makefile - a sample makefile for the program
|
||
README.stinit - this file
|
||
|
||
Changes in version 0.9b:
|
||
- fix back out to SCSI_IOCTL_SEND_COMMAND for 2.4 kernels (2.4 uses errno
|
||
EINVAL for unsupported ioctls)
|
||
|
||
Changes in version 0.9:
|
||
- try first SG_IO for inquiry, if the ioctl fails, try SCSI_IOCTL_SEND_COMMAND
|
||
- error checking for SG_IO is very simplistic for now
|
||
|
||
Changes in version 0.8:
|
||
- in devfs, /dev/tapes/tape<n> does not match <n>th drive after rmmoding
|
||
and insmodding the st driver; fix provided by Philippe Troin
|
||
- put the man page into /usr/share/man/man8
|
||
- counts can use the k, M, or G postfix
|
||
|
||
Changes in version 0.7:
|
||
- the directory scanning for tape devices is restricted to files with
|
||
certain names in some directories to avoid triggering automatic
|
||
module loading for device that don't exist (original patch from
|
||
Philippe Troin)
|
||
- support for devfs (/dev/tapes) added
|
||
- logging bug fixes
|
||
- add setting the cleaning request parameter
|
||
- add setting the no-wait (immediate) bit
|
||
|
||
Changes in version 0.6:
|
||
- fix the bug with whitespace at the beginning of lines
|
||
- use O_NONBLOCK to open the tape (anticipate kernel change)
|
||
|
||
Initial version 0.5.
