I read the instruction from HP but
some body that was installing this software , had to edit the ./INSTALL script because the default script was made for a different kernel according to him.
So he look for the kernel version and edit the ./INSTALL script and run with out error the installation, but this man does not want tell me witch line was edited.
Some body has get practical experience installing this multipath and the driver for qlogic?
The machines are Blades 460.
Thank you
W.S

Solutionmake sure modprobe.conf contain the following:
modify your blacklist in /etc/multipath.conf
blacklist {
devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*"
devnode "^hd[a-z]"
devnode "^cciss!c[0-9]d[0-9]*"
}
above will blacklist other all device except sdxx.
You have configure /etc/multipath.conf correctly but please put } at the end of device defination.
device {
fdf
fdsf
fdf
} <-----
when complete modifying, rescan mpath device
# multipath -ll
# multipath -v3
Post output above and let us know the outcome.

Re: Installing multipath for RHEL 5
yes the INSTALL script in the HP Mutlipath Kit only senses RHEL up to 5.3. You have to edit the INSTALL script as follows:
Add line 41:
40 @rhel53arr=("RHEL5", "release 5", "5.3", "RHEL5U3");
41 @rhel53arr=("RHEL5", "release 5", "5.4", "RHEL5U3");
And your INSTALL script should now install "cleanly"
The INSTALL really simply copies the custom multipath.conf file so your system is ready for all HP StorageWorks Array family.
