I wonder if it is picking the values from internal table.. Try passing the vendor and product ids as below..
device {
vendor "IBM"
product "1814"
..
If this does not work then add "verbosity 5" in default section.. This might produce some useful information..

Hi,
I have the following multipath.conf
[root at blade01 ~]# cat /etc/multipath.conf
defaults {
user_friendly_names yes
}
blacklist {
devnode "^sda$"
}
device {
vendor "*"
product "*"
getuid_callout "/sbin/scsi_id -g -u -s /block/%n"
prio_callout "/sbin/mpath_prio_rdac /dev/%n"
hardware_handler "1 rdac"
features "1 queue_if_no_path"
path_grouping_policy group_by_prio
failback immediate
no_path_retry queue
rr_min_io 1000
path_checker rdac
}
multipaths {
multipath {
wwid 360080e5000183dfe000003754ccffae5
alias red
}
multipath {
wwid 360080e5000183c88000003734ccffa68
alias blue
}
}
I have both "no_path_retry queue" and 'features "1
queue_if_no_path"'.
Nevertheless, it doens't get applied:
[root at blade01 ~]# multipath -ll
blue (360080e5000183c88000003734ccffa68) dm-1 IBM,1814 FAStT

\_ round-robin 0 [prio=0][enabled]
\_ 2:0:1:1 sdd 8:48 [active][ghost]
\_ 1:0:1:1 sdh 8:112 [active][ghost]
Using kernel 2.6.18-194.17.4.el5xen 64 bits from centos.
Any ideas?
Thanks,
Nuno Fernandes
