Thank you for the links to device mapper config guid.e
Since there's no official doc to configure /etc/multipath.conf for MSA 2052. Is below looking good? I just replaced product name from MSA 2040 SAS to MSA 2052 SAS. But the disks are not SAS, but SSD.
device {
vendor "HP"
product "MSA 2052 SAS"
path_grouping_policy group_by_prio
getuid_callout "/sbin/scsi_id -g -u -n -s /block/%n"
prio_callout "/sbin/mpath_prio_alua /dev/%n"
path_selector "round-robin 0"
path_checker tur
hardware_handler "0"
failback immediate
rr_weight uniform
rr_min_io 100
no_path_retry 18
}
