HBA enumeration and multipath configuration
...d varying
combinations of the mapping of HBA to an enumerated /sys node. e.g.:
host0
host2
host3
or
host1
host3
host4
other combinations, etc.
This messes up our multipath filtering for weightedpath priority settings. From /etc/multipath.conf:
defaults {
user_friendly_names no
find_multipaths yes
prio weightedpath
prio_args "hbtl 0:.:.:.* 1 [1-9]:.:.:.* 10"
path_grouping_policy group_by_prio
path_selector "service-time 0"
failback immediate
polling_interval 5
no_path_retry 12
}
The setting for prio_args fails...

dm-multipath do not autoscan partition table
...ts (based on openindiana).

defaults {
find_multipaths yes
user_friendly_names no
# features "1 no_partitions"
}
However when I try this error:

Unrecognised multipath feature request
