[dm-devel] Can't seem to set features=1 queue_if_no_path

[Moger, Babu]

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

 \_ 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,
