Host readiness

The following instructions specify how to configure an Oracle VM Server host connected to InfiniBox.

  1. Connect to the server using the following command. Provide the root password. 

    ssh root@server-name
  2. Create a backup version of the multipathing configuration file: 

    cp /etc/multipath.conf /etc/multipath.conf.bak
  3. Create a new multipathing configuration file: 

    vi /etc/multipath.conf 

    The content of the file should be: 

    defaults {
    max_fds 8192
    queue_without_daemon no
    user_friendly_names yes
    }
    devices {
    device { 
    vendor "NFINIDAT"
    product "InfiniBox.*"
    prio alua
    path_grouping_policy group_by_prio
    path_checker tur
    path_selector "round-robin 0"
    features "0"
    failback 30
    rr_weight priorities
    no_path_retry fail
    rr_min_io 1 # for kernels up to 2.6.31
    rr_min_io_rq 1 # for kernels 2.6.31 or newer
    flush_on_last_del yes
    fast_io_fail_tmo 14
    dev_loss_tmo 15
    }
    }
    blacklist {
    }
  4. Apply the new configuration and restart the multipathing daemon: 

    mpathconf --enable --with_multipathd y --with_chkconfig y
    /etc/init.d/multipathd restart
    chkconfig multipathd on
  5. Create a new fibre channel driver parameters configuration file: 

    vi /etc/modprobe.d/infinidat.conf 
    The content of the file should be: 
    options qla2xxx ql2xmaxqdepth=128 ql2xenablemsix=0 ql2xextended_error_logging=507510784
    options lpfc lpfc_hba_queue_depth=128 lpfc_lun_queue_depth=128 lpfc_devloss_tmo=5 lpfc_log_verbose=0xff
  6. Create a new initial ramdisk image: 

    dracut -f /boot/initramfs-`uname -r`.img
  7. Reboot the server: 

    reboot
