/lib/modules/‘uname -r‘/drivers/addon/hbaDriver
where uname -r is the string returned to the console by the uname -r command
and
hbaDriver is the name of the HBA driver module
ii. If you are using SuSE Linux:
/lib/modules/‘uname -r‘/drivers/scsi
where uname -r is the string returned to the console by the uname -r command
If you have Red Hat Linux 3.0 SuSE Linux SLES 8 SP3 or higher, you no
longer need to build the HBA driver modules and copy them to the above
location. The pre-built kernel now includes these modules.
b. Save your kernel change.
STEP 3. Change the Linux configuration files.
a. If you are using Red Hat Linux:
i. Edit the
/etc/modules.conf file to add an alias for each HBA.
In the sample file below, the second and third lines are aliases for HBAs;
driverModule in these entries is the name of the HBA driver module.
alias eth0 eepro100
alias scsi_hostadapter1
driverModule
alias scsi_hostadapter2 driverModule
ii. Enable the following parameters in
/etc/modules.conf:
max_scsi_luns
scsi_allow_ghost_devices
You must enable the last parameter so that you do not have to recompile the
kernel to properly connect a Linux server to the storage system.
For example, in the following
modules.conf file, the max_scsi_luns and
scsi_allow_ghost_devices parameters are enabled:
alias parport_lowlevel parport_pc
alias scsi_hostadapter1
driverModule
alias scsi_hostadapter2 driverModule
alias eth0 tla
options scsi_mod max_scsi_luns=256 scsi_allow_ghost_devices=1
where driverModule is the name of the HBA driver module for accessing the
storage system.
iii. Edit the
/etc/modprobe.conf file as follows:
^ For QLogic HBAs, make sure that the
ql2xfailover and the ConfigRequired
parameters are set to 0:
options qla2xxx q12xfailover=0 ConfigRequired=0
The variables x and xxx vary with the HBA model.
^ For Emulex HBAs, set the value of the
lpfc_nodev_tmo parameter to 10:
options lpfc lpfc_nodev_tmo=10
