[dm-devel] help with hds DF500F

[Michael Di Domenico]

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:
