Release Notes

Linux setup and configuration
23 Dell EMC PowerVault ME4 Series and Linux | 3924-BP-L
Note: Dell EMC recommends using the native Linux multipath solution with ME4 Series storage.
3.2.2 Configure multipath for ME4 Series storage
The native Linux multipath software comes with a set of default settings for an extensive list of storage
models from different vendors. The default settings allow the software to work with the ME4 Series system
right out of the box. However, these settings might not be optimal for all situations and should be reviewed
and modified if necessary. It is highly recommended to create a specific ME4 Series device section in the
configuration file. An example configuration is shown as follows:
defaults {
find_multipaths yes
user_friendly_names yes
}
blacklist {
}
devices {
device {
vendor "DellEMC"
product "ME4"
path_grouping_policy "group_by_prio"
path_checker "tur"
hardware_handler "1 alua"
prio "alua"
failback immediate
rr_weight "uniform"
path_selector "service-time 0"
}
}
multipaths {
multipath {
wwid "3600c0ff0003c589f1e4b6b5b01000000"
alias app-data-01
}
}
