If you loaded the HBA, NIC or iSCSI HBA driver as a module (not as a static kernel driver), use lsmod to verify that all extensions are loaded.

If you built the HBA, NIC or iSCSI HBA driver as a module and modified /etc/modules.conf to specify that the driver be loaded before the PowerPath drivers, the driver name appears in the lsmod output below the PowerPath drivers. For example:

ModuleSizeUsed byTainted: PF emcphr96240(unused) emcpmpap1050240(unused) emcpmpaa721600(unused) emcpmpc920640(unused) emcpmp558400(unused) emcp5425200[emcphr emcpmpap emcpmpaa

emcpmpc emcpmp] emcpsf68200[emcpmpap emcp]

...

driver_module6843801

sg mptscsih driver_module sd_mod]

where driver_module is the name of the HBA, NIC or iSCSI HBA driver module.

The /etc/modules.conf file should look similar to the following:

alias ppfilter emcpsf

pre-install emcpsf modprobe sd_mod

add options emcp hostid=00:C0:9F:35:4A:30 insmod_opt=-N

alias power_path emcp add above emcp emcpmp add above emcpmp emcpmpc add above emcpmpc emcpmpaa add above emcpmpaa emcpmpap add above emcpmpap emcphr add above emcphr emcpioc post-install emcpioc rmmod emcpioc

add options emcp managedclass="hpxp","ess","hitachi","hphsx" add below emcp driver_module

alias scsi_ppfilteradapter driver_module post-install emcpsf modprobe driver_module

pre-remove emcpsf rmmod emcpmpaa emcpmpc emcpmp emcp

where driver_module is the name of the HBA, NIC or iSCSI HBA driver module.

STEP 15. If the server is running SuSE Linux SLES8 and a kernel version newer than 2.4.21-138, rebuild the ramdisk:

a.Edit the /etc/sysconfig/kernel file to ensure that the HBA driver is always loaded after the internal SCSI adapter driver as follows:

INITRD_MODULES="scsi_mod sd_mod cciss reiserfs driver_module"
