Comment 14 michal novacek 2009-10-21 17:07:43 UTC
old version: 0.4.7-30.el5
new version: 0.4.7-30.el5_4.1

I added the following piece to /etc/multipath.conf and restarted multipath:
       device {
               vendor                  "STK"
               product                 "FLEXLINE 380"
               getuid_callout          "/sbin/scsi_id -g -u -s /block/%n"
               prio_callout            "/sbin/mpath_prio_rdac /dev/%n"
               features                "0"
               hardware_handler        "1 rdac"
               path_grouping_policy    group_by_prio
               failback                immediate
               rr_weight               uniform
               no_path_retry           queue
               rr_min_io               1000
               path_checker            rdac

I verified that running 'multipathd -k"show config"' ignores the configuration
with old version and recognizes it correctly for new version.

Customer confirmed that the issue is fixed.

Updated from the customer.
Latest test using RHEL 5.4 with no modified rpm's  

multipath -ll -v2 returns expected result.
dd if=/dev/zero of=/mountpoint dumps data at expected speed.

Non modified initrd causes so many errors that it slows up the boot by four and a half minutes, when compared to running modified initrd:
mkinitrd -f /boot/initrd-$(uname -r).img $(uname -r) --preload=scsi_dh_rdac
