Hi All,
I'm having problems to put the Multipathing tools to work correctly with
NetApp Cluster Solution.
I have a xenpool with 3 machines the multipathing are enabled on them,
the HBA are Qlogic, two FAS3140 controllers in Cluster. I created a lun
to be a storage repository (SR), the lun is visible and was recognized
on the 3 machines, but when we say to the XenServer to build a SR with
this Lun, all I/O operations arrive to the FAS3140 by the non-optimized
path.
*XenServer multipath.conf*
defaults {
user_friendly_names no
}
devices {
device {
vendor "NETAPP"
product "LUN"
path_grouping_policy group_by_prio
getuid_callout "/sbin/scsi_id -g -u -s /block/%n"
prio_callout "/sbin/mpath_prio_netapp /dev/%n"
features "1 queue_if_no_path"
path_checker directio
failback immediate
}
}
We made two tests, one with prio_callout as /sbin/mpath_prio_alua and
other with prio_callout as /sbin/mpath_prio_netapp, both returns the
same results.
What's the output of 'multipath -ll'?
Looks like all paths are configured into one group here.
Cheers,
Hannes
