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
add options emcp hostid=00:C0:9F:35:4A:30
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
add options emcp managedclass="hpxp","ess","hitachi","hphsx" add below emcp driver_module
alias scsi_ppfilteradapter 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
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"
