I have a Hitachi DF500F that i'm trying to redundantly connect. I've
got a single QLogic HBA dual-port. Both ports are connected to an FC
switch. The HDS unit has four ports, two per controller. All four
ports are connected to the FC switch also. This is on RedHat 5
x86_64.
I'm trying to setup multipath, but i can't seem to figure out the correct setup.
I also noted two things that seem like bugs. I used the 'make rpm' to
build and rpm of multipath, however there were several files not
included in the rpm which caused it to fail, so i added those to the
%files section.
Also the RPM doesnt seem to include the
/etc/init.d/multipathd.init.redhat file for me, i had to hand copy it
over.
I'm sure i'm doing something wrong, i just dont know what it is.
Thanks
Here is my /etc/multipath.conf file:
defaults {
polling_interval 120
udev_dir /dev
rr_weight priorities
failback immediate
}
blacklist {
devnode cciss
devnode fd
devnode hd
devnode md
devnode sr
devnode scd
devnode st
devnode ram
devnode raw
devnode loop
devnode "^sda$"
}
devices {
device {
vendor "HITACHI"
product "DF500F"
path_grouping_policy group_by_prio
prio_callout "/sbin/mpath_prio_hds_modular %d"
getuid_callout "/sbin/scsi_id -g -u -s /block/%n"
}
}
here is what happens when i run multipath:
