RH EL 4.6 / Qlogic driver

Hi all,

I have a server running RedHat EL 4.6 connected to two EVA 4400 using Qlogic FC cards.
In order to use multipathing, I'm trying to install the Qlogic driver provided by HP.

OS is actually installed using default driver. Each LUN is seen 4 times. I compiled the src package provided and system cannot boot sending messages like :
insmod: error inserting '/lib/qla2xxx.ko': -1 Invalid module format
ERROR: /bin/insmod exited abnormally: (pid 457)

Seems like a compilation option isn't good... Package used is hp_qla2x00src-mezz-8.01.07.25-4.noarch.rpm

Does anybody know of a way to solve such an issue ?

Regards,

Fred

Re: RH EL 4.6 / Qlogic driver

via installation media, boot the system in rescue mode, and remove/uninstall the package

then boot the system normally, and start service (/etc/init.d/multipath start).

almost all Linux has multipath built-in, so I hope you dont need to install it from another source.

Ok, see first start the multipath server, as
# /etc/init.d/multipath start
and also make the server auto start
# chkconfig multipath on

now run 'fdisk -l', you will see '/dev/dm0' .. is yes then it means that multipathing is working.

Well, I thought that using Qlogic builtin multipath was better than a software one. But if this is the only way I can go...

Re: RH EL 4.6 / Qlogic driver

after reading some docs, multipathd is placed on top of LVM Structure. It does not manage multipathing at device level (sda, sdb....).

I already have software RAID activated (mdadm).
