He wants the RDAC hw handler and its path checker (rdac). The MD3000i is an
LSI re-branded box and is the same as the IBM DS3300.

Here is the multipath.conf he should be using for MD3000i (or for the DS3300
but will need to modify the vendor/model entry)
# Note: The same as the IBM DS3300
#
device {
vendor "DELL"
product "MD3000i"
product_blacklist "Universal Xport"
features "1 queue_if_no_path"
path_grouping_policy group_by_prio
hardware_handler "1 rdac"
path_checker rdac
prio "rdac"
failback immediate
}
