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"
}
