I have compiled a new Intel Modular Server multipath driver for Citrix XenServer 6.2 XS62SP1 kernel based on instructions on my earlier post:
Download the new driver for XenServer 6.2 XS62SP1 kernel from here:
scsi_dh_alua_intelmodular_cbvtrak_xs62sp1.i386.tar.gz
Looks like this driver rpm is not needed at all since XenServer 6.2.
Only use multipath.conf file from this package.
