Hi Emmanuel,<br>
<br>
it's a merge of the default settings I've taken from the<br>
/usr/share/doc/package/multipath-tools/multipath.conf.annotated and the<br>
OPEN-* section of the HPDMmultipath-4.4.1 multipath.conf.HPTemplate.SLES11<br>
file, here it is:<br>
<br>
<br>
defaults {<br>
udev_dir /dev<br>
polling_interval 5<br>
selector "round-robin 0"<br>
prio const<br>
user_friendly_names no<br>
getuid_callout "/lib/udev/scsi_id --whitelisted<br>
--device=/dev/%n"<br>
failback manual<br>
no_path_retry fail<br>
}<br>
blacklist {<br>
devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*"<br>
devnode "^hd[a-z][[0-9]*]"<br>
}<br>
blacklist_exceptions {<br>
}<br>
multipaths {<br>
multipath {<br>
alias "san"<br>
wwid "360060e8006d2e1000000d2e1000000e6"<br>
}<br>
}<br>
devices {<br>
# For XP arrays<br>
<br>
device {<br>
vendor "HP"<br>
product "OPEN-.*"<br>
path_grouping_policy multibus<br>
path_selector "round-robin 0"<br>
rr_min_io 1000<br>
rr_weight uniform<br>
path_checker tur<br>
# no_path_retry 18<br>
# hardware_handler "0"<br>
# failback immediate<br>
# getuid_callout "/lib/udev/scsi_id -g -u /dev/%n"<br>
}<br>
<br>
}<br>
<br>
I've commented out some of the HP template device lines due to the<br>
recommended configuration for clustering, read in the SLES 11 Sp1 Storage<br>
Administration Guide:<br>
<br>
"We recommend failback setting of "manual" for multipath in cluster<br>
environments in order to prevent multipath failover ping-pong."<br>
<br>
and in the mailing list: " Fourth, don't run SBD on queue_if_no_path MPIO."<br>

And this my multipath -ll output:<br>
