/lib/modules/‘uname -r‘/drivers/addon/hbaDriver

where uname -ris the string returned to the console by the uname -rcommand 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 -ris the string returned to the console by the uname -rcommand

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
