Configure Fibre Channel
Set the storage type to FC and the various configuration parameters for multipath:
juju config storage-connector storage-type='fc' \
multipath-defaults='{"user_friendly_names":"yes", "find_multipaths":"yes", "polling_interval":"10"}' \
multipath-devices='{"vendor":"PURE", "product":"FlashArray", "fast_io_fail_tmo":"10", "path_grouping_policy":"group_by_prio"}'
The above multipath-devices config will produce this device specific configuration in the final rendered /etc/multipath/conf.d/storage-connector-multipath.conf file.
device {
vendor "PURE"
product "FlashArray"
fast_io_fail_tmo 10
path_grouping_policy "group_by_prio"
}
