hi georg
default parameters work fine, i only add a "features" in device section, i use it on a CENTOS environment:
blacklist {
devnode "sda"
}
defaults {
user_friendly_names yes
find_multipaths no
}
devices{
device {
features "1 queue_if_no_path"
}
}

Re: multipath.conf needed for SLES 11 SP2 P4000
Hi.
After gathering some information on the internet, I finally configured mine multipath
on Centos 6.3 with P4500 G2 box as :
defaults {
user_friendly_names yes
no_path_retry 1
queue_without_daemon no
max_fds max
}
devices {
device {
vendor "LEFTHAND"
product "iSCSIDisk"
path_grouping_policy multibus
getuid_callout "/lib/udev/scsi_id --whitelisted --device=/dev/%n"
features "1 queue_if_no_path"
path_checker directio
failback immediate
#rr_min_io 100 - defaults on older kernels, RHEL specific
rr_min_io_rq 1
rr_weight uniform
}
}
