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: 

   devices {
   device { 
   vendor "NFINIDAT"
   product "InfiniBox.*"
   prio alua
   hardware_handler "1 alua"
   failback immediate
   detect_prio yes
   path_grouping_policy group_by_prio
   path_checker tur
   path_selector "round-robin 0"
   features "0"
   rr_weight priorities
   no_path_retry queue
   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 15
   dev_loss_tmo "infinity"
   user_friendly_names no
   }
   }
   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

Provisioning

Provisioning storage resources is done from InfiniBox (using either of the following : GUI, InfiniShell, API, InfiniSDK). Provisioning tasks are documented here: 

• Accessing InfiniBox
  • Accessing the InfiniBox GUI
  • Accessing the InfiniShell Console
  • More access options:
    • Using the InfiniBox API
    • Using the InfiniSDK
• Creating a cluster and host on InfiniBox
  • Creating a cluster
  • Creating a host
  • Adding a host to a cluster
  • Viewing the host connectivity
• Provisioning volumes
  • Creating a pool 
    • Relevant only if a pool was not created by the storage admin
  • Creating a volume
• LUN masking
  
  • Mapping a volume to a host or a cluster
