HBA enumeration and multipath configuration
...ons, 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 to set the correct path map topology and priority against an HBA as
I can't predict what HBA is what. Consistently iSCSI claims the...

Hello, I hope to be in the right list. my question is the following. I

Multipathing with Sun 7310
Dear list,
we have a relatively new Sun Storage 7310, where we connect CentOS 5.5
Servers (IBM LS21/LS41 Blades) via Brocade Switches, 4GBit FC. The Blades
boot from SAN via qla2xxx, and have no harddisks at all. We want them to
use multipathing from the very beginning, so /boot and / are already seen
by multipathd. Problem is, that the Sun 7310 has two storage heads which
run in
