I got new source for Version 2.01 from the mpath_prio_hds_modular author.
Version 2.01
    Changes 2007-11-13:

      o Source code changes:

        § Delete #include <libdevmapper.h>

        § Delete char vendor[8]

        § Add char vendor[9]

Compiled it with:

 # gcc pp_hds_modular.c –o mpath_prio_hds_modular
 Copy the prioritizer:
 # cp mpath_prio_hds_modular /sbin

Now mpath_prio_hds_modular works correctly:

root@tie-interceptor:/# /sbin/mpath_prio_hds_modular -v /dev/sda
VENDOR: HITACHI
PRODUCT: DF600F
SERIAL: 0x
LDEV: 0x0007
CTRL: 2
PORT: A
CTRL EVEN, LDEV ODD, PRIO 0
0

However one part of the multipath package seems to be missing from the ubuntu package.
multipath normally requires /sbin/scsi_id to exist.

Looks like udev puts scsi_id in a strange place, and there is an existing bug
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=481447 for that.

So I symlinked the /lib/udev/scsi_id to /sbin/scsi_id

However the version of scsi_id that is there does not support the -s flag and fails:

root@tie-interceptor:/sbin# multipath
/sbin/scsi_id: invalid option -- 's'
error calling out /sbin/scsi_id -g -u -s /block/sda
/sbin/scsi_id: invalid option -- 's'

It appears that the version of scsi_id that is supplied with ubuntu is a bit different than the version in RH, or SUSE.

root@tie-interceptor:/sbin# /lib/udev/scsi_id --version
141

[ewr2san (mark-perino)]

So Ive got it working now.

Here's what I did.

1. Compile pp_hds_modular.c 2.01 (attached)
# gcc pp_hds_modular.c –o mpath_prio_hds_modular
 Copy the prioritizer:
# cp mpath_prio_hds_modular /sbin

2. Copy multipath.conf into /etc (attached)

3. Edit /etc/multipath.conf
Change lines (2) that say:
                getuid_callout "/sbin/scsi_id -g -u -s /block/%n"
To:
                getuid_callout "/lib/udev/scsi_id --whitelisted --device=/dev/%n"

Hi,

I was wondering if you were still having this problem.

Regards

[ewr2san (mark-perino)]

I gave up. I got somethings working, but decided to wait and try
again when karmic comes out.
