HBA enumeration and multipath configuration
...uration of this host we have had 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
}

dm-multipath do not autoscan partition table
...or accessing these disks I use dm-multipath, since I use 2 separate
networks for access. For these reasons I want host system to force not
to scan dm-multipath disks for partitions. According to multipath.conf
man there should be feature to do it
defaults {
find_multipaths yes
user_friendly_names no
# features "1 no_partitions"
}
However when I try this error:

Multipath pools - practical for use?
Hi all,
Writing up some Fedora documentation, and looking to figure out the best
way of mapping multipath network(!) LUNs to pools in libvirt.
ie Infiniband SRP LUNs, but would probably apply to Fibre Channel
equally as well.
There are two approaches I can think of easily:
a) Large LUNs (ie TB+) that are mapped to a host server as disk, with
each LUN being configured as an LVM

Device-mapper-multipath not working correctly with GNBD devices
...Port : 14567
State : Open Connected Clear
Readonly : No
Sectors : 41941688
#
After, I have configured the device-mapper multipath by commenting the
"blacklist" section in /etc/multipath.conf and adding this "defaults"
section:
defaults {
user_friendly_names yes
polling_interval 5
#path_grouping_policy failover
path_grouping_policy multibus
rr_min_io 1
failback immediate
#failback manual
no_path_retry fail
#no_path_retry queue
}
Now I have the mpath device configured correct...

dm-multipath use
Are folks in the Centos community succesfully using device-mapper-multipath?
I am looking to deploy it for error handling on our iSCSI setup but there
seems to be little traffic about this package on the Centos forums, as far
as I can tell, and there seems to be a number of small issues based on my
reading the dm-multipath developer lists and related resources.
