WARNING: This driver is not finished, USE ONLY FOR TESTING.
|
|
|
|
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. The
|
|
update for SCST was made and supported by Stanislaw Gruszka
|
|
<stanislawg1@open-e.com>.
|
|
|
|
Driver operate same hardware as qla2x00tgt, but have one adventage over it:
|
|
support of 24xx series of Qlogic adapters.
|
|
|
|
INSTALLATION:
|
|
|
|
Build driver with command
|
|
$ make
|
|
|
|
Copy proper firmware image for your HBA from Qlogic FTP server
|
|
ftp://ftp.qlogic.com/outgoing/linux/firmware/ to one of linux firmware loader
|
|
directories (see udev/hotplug documentation for your distribution)
|
|
|
|
Next step depends on you have other QLA modules installed. Note that you can't
|
|
load ISP driver when you build other Qlogic drivers in kernel (kerel oops may
|
|
occur). Other QLA modules are acceptable, but extra care is needed, firs copy
|
|
modules to some directory, ie:
|
|
|
|
$ mkdir /root/qla_isp
|
|
$ cp linux-2.6/build/*.ko /root/qla_isp
|
|
|
|
Everytime you want to run qla_isp, unload all other qla modules
|
|
|
|
$ rmmod qla2x00tgt
|
|
$ rmmod qla2400
|
|
$ rmmod qla2300
|
|
$ rmmod qla2200
|
|
$ rmmod qla2xxx
|
|
|
|
and load ISP modules directly from created directory, ie:
|
|
|
|
$ insmod /root/qla_isp/isp_scst.ko
|
|
$ insmod /root/qla_isp/isp_mod.ko
|
|
|
|
If you have no others QLA drivers from SCST (qla2x00tgt) nor kernel (qla2xxx
|
|
and friends) you can install in standard /lib/modules directory:
|
|
|
|
$ make install
|
|
$ depmod -ea
|
|
|
|
Then first time load drivers by hand:
|
|
|
|
$ modprobe isp_scst
|
|
$ modprobe isp_mod
|
|
|
|
Now anytime the system boot and QLA card is plugged, modules will load
|
|
automatically.
|
|
|
|
When driver is loaded, enable all logical units for each channel to work in
|
|
target mode. You need to write string in form "channel:enable" to procfs
|
|
configuration file, ie:
|
|
|
|
$ echo 0:1 > /proc/scsi_tgt/qla_isp/0
|
|
|
|
To unload isp_mod.ko module you must disable target mode for all channels ie:
|
|
|
|
$ echo 0:0 > /proc/scsi_tgt/qla_isp/0
|
|
$ echo 1:0 > /proc/scsi_tgt/qla_isp/0
|
|
|
|
Enable/disable target mode is not the same as switching target/initiator role.
|
|
If you have more then one device, role of each you can set using isp_roles
|
|
parameter, like in example:
|
|
|
|
$ modprobe isp_mode isp_roles="b0300=initiator"
|
|
|
|
Magic number "b0300" is DEVID value, which you can find in /proc/scsi/isp/X
|
|
|
|
To attach logical units continue with normal SCST setup
|
