Hi all,

 

I am curently installing HU6.1 and SDU 5.1 on a SUSE 11 SP2 Linux . later I will use SMO 3.3 with it.

I am using EMULEX HBAs  in it. The Konfig is ok as I checked it in the interoperability matrix!

 

oralip05:/var/log # sanlun fcp show adapter -v

 

adapter name:      host1

WWPN:              10000000c98f7a84

As you can see HU 6.1 is working.

 

I use the the following  multipath.conf file:

oralip05:/var/log # cat /etc/multipath.conf

defaults {

        user_friendly_names     no

        max_fds                 max

        queue_without_daemon    no

        flush_on_last_del       yes

}

 

blacklist {

        wwid    36003005700a5e29013154d5f3409ca21

        devnode "^hd[a-z]"

        devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*"

        devnode "^cciss.*"

}

 

devices {

     device {

        vendor                  "NETAPP"

        product                 "LUN"

        getuid_callout          "/lib/udev/scsi_id -g -u -d /dev/%n"

        prio                    "alua"

        features                "3 queue_if_no_path pg_init_retries 50"

        hardware_handler        "1 alua"

        path_grouping_policy    group_by_prio

        failback                immediate

        rr_weight               uniform

        rr_min_io               128

        path_checker            tur

        }

}

 

Looks like Mutlipath is working also:

oralip05:/var/log #

 

when I install Snapdrive 5.1 and edit the snapdrive.conf file like this:

Host platform      default transport   multipathing     fstype      vmtype

                         type                    type

-------------------     -----------------------     -----------------     ---------     -------------

Linux               FCP                     nativempio           ext3           lvm

 

I get the following error:

oralip05:/var/log # snapdrived start

WARNING!!! Unable to find a SAN storage stack. Please verify that the appropriate transport protocol, volume manager, file system and multipathing type are installed and configured in the system. If NFS is being used, this warning message can be ignored.

 

Successfully started daemon

oralip05:/var/log #

 

This message I do not understand as I am using the combination of the parameters in the snapdrive.conf file that is in the docu.

 

When I try the following command I get the following message:

oralip05:/var/log # snapdrive storage show -all

 

WARNING: This operation can take several minutes

          based on the configuration.

0001-185 Command error: storage show failed: no NETAPP devices to show or add the host to the trusted hosts (options trusted.hosts) on the storage system or retry after changing snapdrive.conf to use https for storage system communication and restarting snapdrive daemon.

oralip05:/var/log #

 

As this command need to run and not fail I know I am in trouble!

 

Anyone knows what I have missed or can give me some hints?

 

Thanks

    Hello Horst,

     

    Couple of things. Can you please check if you are running at following software version and configuration. This information is available in IMT too.

     

    (1) lvm2-2.02.84-3.33.1

    (2) device-mapper-1.02.63-18.27.1

    (3) add 'udev_sync = 1' to activation section of /etc/lvm/lvm.conf

     

    I assume sg3_utils.rpm is already installed.

     

    Thanks,

    Himanshu

      Hi Himanshu,

       

      Thanks for your reply. I have the following installed:

      oralip05:/ # rpm -qa | grep lvm

      lvm2-2.02.84-3.37.1

      oralip05:/ # rpm -qa | grep device-mapper

      device-mapper-1.02.63-18.27.1

      device-mapper-32bit-1.02.63-18.27.1

      oralip05:/ # grep udev_sync /etc/lvm/lvm.conf

          udev_sync = 1

      oralip05:/ # rpm -qa | grep sg3

      sg3_utils-1.31-1.17.1

      oralip05:/ #

       

      So not the exact Version like in the documentation but newer!

       

      Thanks

      Horst

        Hi all,

         

        Problem solved. I had to install a 32bit package:

        oralip05:~ # rpm -qa | grep libnl

        libnl-32bit-1.1-49.22.4.1

        libnl-1.1-49.18

        oralip05:~ #

         

        The 64 bit package of libnl was installed so we installed the 32-bit version of libnl afterwards.This was done by YAST.

        then I had to stop/start snapdrived:

        oralip05:/ # snapdrived stop

        Successfully stopped daemon

        oralip05:/ # snapdrived start

        Successfully started daemon

        oralip05:/ #

         

        Now the snapdrive command works like a charm:

        oralip05:/ # snapdrive storage show -all
