This bug has been copied from bug #515171 and has been proposed
to be backported to 5.4 z-stream (EUS).
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:
product "FLEXLINE 380"
getuid_callout "/sbin/scsi_id -g -u -s /block/%n"
prio_callout "/sbin/mpath_prio_rdac /dev/%n"
hardware_handler "1 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
