Phoenix Hardware and OS related services description

Here are described the infrastructure services run on, together with procedures related to them, drivers, incompatibilities, monitoring, testing and other useful information. We will have two sections: Hardware Cards and OS Features.

Hardware Cards

Here is a list of the Hardware Cards we have filled in so far. You can add new ones in HardwareCards.

Hardware control.

The ILOM network is in a separate network (192.168.*). You can access it through the Xen hosts (i.e. Xen12) and perform ON/OFF commands with ion, ioff or ireset

VNIC setup

To set the VNIC on any machine, we need to install all the mlx4 packages available from the MLNX ISO and configure a few files:

  1. If the kernel and/or the SL version, download the right ISO file from the Mellanox website (http://www.mellanox.com/content/pages.php?pg=products_dyn&product_family=26&menu_section=34#tab-three).
  2. Do the following steps:
     mount -o loop ./MLNX_OFED_LINUX-1.5.3-3.0.0-rhel6-x86_64.iso  /mnt
    cp -r /mnt/ ./mlnx 
    # MAKE SURE .mlnx is also copied
    umount /mnt
    cd mlnx/docs
    vim mlnx_add_kernel_support.sh
    # add this so the script detects SL as redhat: 
    # sl-release-*6.0*|
    ./mlnx_add_kernel_support.sh --iso /root/MLNX_OFED_LINUX-1.5.3-3.0.0-rhel6-x86_64.iso
    # Once it is finished, the new image is created in /tmp, replace the one we downloaded with it:
    mv /tmp/MLNX_OFED_LINUX-1.5.3-3.0.0-rhel6-x86_64.iso /root/
    mount -o loop ./MLNX_OFED_LINUX-1.5.3-3.0.0-rhel6-x86_64.iso  /mnt
    /mnt/mlnxofedinstall
    # Done! 
  3. Once these steps are done, reboot the machine.
  4. If the package infiniband-diags is not installed, install it from the iso image just created. This package provides utilities that we can use to test the status of the infiniband fabric. In particular, ibstat, ibstatus, ibhosts, ibswitches and ibping are really useful.
  5. At this point, the infiniband card should be up and running if the ifcfg-ib0 file is correct and the fabric is properly connected.
  6. To install the VNIC, modify /etc/infiniband/openib.conf
    sed -i -e 's/MLX4_VNIC_LOAD=no/MLX4_VNIC_LOAD=yes/' /etc/infiniband/openib.conf
    And create /etc/infiniband/mlx4_vnic.conf as follows (in this example, eth0 has the 10.10 IP):
    VMAC1=`ifconfig |grep eth0|awk '{print $5}'|awk --field-separator ":" '{print $1}'`
    VMAC2=`ifconfig |grep eth0|awk '{print $5}'|awk --field-separator ":" '{print $2}'`
    VMAC3=`ifconfig |grep eth0|awk '{print $5}'|awk --field-separator ":" '{print $3}'`
    VMAC4=`ifconfig |grep eth0|awk '{print $5}'|awk --field-separator ":" '{print $4}'`
    VMAC5=`ifconfig |grep eth0|awk '{print $5}'|awk --field-separator ":" '{print $5}'`
    VMAC6=`ifconfig |grep eth0|awk '{print $5}'|awk --field-separator ":" '{print $6}'`
    
    IP=`/sbin/ifconfig eth0 | grep 'inet addr:' | awk ' { print $2 } ' | cut -d. -f4-`
    SN=`expr $IP + 100`
    
    echo "name=eth2 mac=00:00:${VMAC3}:${VMAC4}:${VMAC5}:${VMAC6} ib_port=mlx4_0:1 vnic_id=${SN} bx=00:02:C9:03:00:11:11:77 eport=A10" > /etc/infiniband/mlx4_vnic.conf
  7. Then, create the proper file ifcfg-eth2 and the VNIC should be working well.
