This is SCST driver for ISP Qlogic chipsets commonly used in many SCSI and FC host bus adapters. Supported chipset are listed in README file, incomplete list of supported HBA's is in doc/Hardware.txt . It is based on Matthew Jacob's multiplatform driver for ISP chipsets, which can be download from ftp://ftp.feral.com/pub/isp/isp_dist.tgz git-svn-id: http://svn.code.sf.net/p/scst/svn/trunk@135 d57e44dd-8a1f-0410-8b47-8ef2f437770f

Target Mode usage instructions (for 2.4.X)
|
|
|
|
A. Build for target mode enabled, use the target 'tgt', as in:
|
|
|
|
make tgt
|
|
|
|
Static compilation into the kernel isn't supported.
|
|
|
|
B. Install scsi_tgt.o && isp_mod.o into the appropriate places, e.g.:
|
|
|
|
|
|
For 2.4.X:
|
|
cp isp_mod.o /lib/modules/RELEASE/kernel/drivers/scsi
|
|
cp scsi_target.o /lib/modules/RELEASE/kernel/drivers/scsi
|
|
|
|
where RELEASE is the full kernel release number you build against.
|
|
|
|
C. Type 'depmod -a'. Type 'modprobe isp_mod' to load both isp_mod and the
|
|
scsi_tgt module. Usually the loader will pull in scsi_tgt.o as needed,
|
|
but you can alwyas do 'modprobe scsi_tgt' by itself first.
|
|
|
|
You can also add 'isp_debug=0xXXXX' to turn on debugging for target
|
|
mode- See ispvar.h for good values to try- but 0xe0f is a good healthy
|
|
amount to try.
|
|
|
|
If you load scsi_tgt.o first, you can add 'scsi_tdebug=1' to the
|
|
load line as well.
|
|
|
|
This now leaves you with isp loaded, and registered with scsi_target, but
|
|
with no LUNs enabled.
|
|
|
|
D. Do
|
|
|
|
scsi_target_ctl enable ispN channel target lun
|
|
|
|
where 'N' is the unit you want to enable a lun on (lun 0 must be first),
|
|
channel the port number (this really applies only to dual bus
|
|
SCSI cards), target (which is ignored) and lun.
|
|
|
|
Use disable to disable a lun. Lun 0 must be last out as it was
|
|
first in.
|
|
|
|
E. Things missing
|
|
|
|
The discerning amongst you will note that scsi_target is incomplete
|
|
at best. That is by design- it's up to *you* to write interesting
|
|
replacements for it.
