Multipath settings for MD36xxf on Linux 5.8

Hi,

Needed help on setting up multipath.conf for DELL powervault MD36xxf on Linux 5.8.

We are using device mapper multipath.

Currently the settings under defaults and device section are:

defaults {

udev_dir /dev
polling_interval 10
selector "round-robin 0"
path_grouping_policy multibus
getuid_callout "/sbin/scsi_id -g -u -s /block/%n"
prio const
path_checker readsector0
rr_min_io 100
max_fds 8192
rr_weight priorities
failback immediate
no_path_retry fail
user_friendly_names yes
}

device {

vendor "DELL"
product "MD36xxf"
path_grouping_policy group_by_prio
path_checker rdac
path_selector "round-robin 0"
hardware_handler "1 rdac"
failback immediate
features "2 pg_init_retries 50"
no_path_retry 30
rr_min_io 100
prio_callout "/sbin/mpath_prio_rdac /dev/%n"
}

are the settings correct for Linux 5.8? We do not have "/sbin/mpath_prio_rdac installed on our system.

I could not find any DELL manuals stating configuration specific to MD36xxf series.

Can someone please help?
