HP 3PAR RedHat and Oracle Linux Implementation Guide

For ALUA Settings in RHEL 5.8
For RHEL 5.0 through RHEL 5.5
NOTE: The following multipath settings for the RHEL server apply regardless of the HP 3PAR
OS version running on the HP 3PAR StoreServ Storage array with a persona 1 setting:
# cat /etc/multipath.conf
defaults {
}
devices {
device {
vendor "3PARdata"
product "VV"
no_path_retry 12
features "0"
hardware_handler "0"
path_grouping_policy multibus
path_selector "round-robin 0"
rr_weight uniform
rr_min_io 100
path_checker tur
failback immediate
polling_interval 5
}
}
If the HP 3PAR StoreServ Storage array that the RHEL server is connecting to is running an
HP 3PAR OS version 3.1.3 or later, you must change the host persona to 2 (ALUA) and modify
the /etc/multipath.conf file.
