Problem:

How do I zone my Compellent array for Oracle RAC?

Solution:

Zoning is performed on the Fibre Channel switches that connect the Compellent storage systems to host servers. 

 The following example illustrates how to create zoning on Brocade 5300 Fibre Channel switch.

  1. Log into the GUI management window.
  2. Click the “Zone Admin” link in the upper left of the GUI window.



  3. This opens the zone administration window such as the one shown below.



  4. The following zones needs to be created:
    1. One zone with all WWN’s of front end physical ports that are connected to the switch.  (See step 5 on how to determine the WWN’s of front end physical ports).
    2. One zone with server WWN’s plus all front end virtual ports WWN’s.  Create additional zones for each additional server.  (See step 6 on how to determine the WWN’s of front end virtual ports.  See step 7 on how to determine of the server WWN).
  5. The WWN’s of front end physical ports can be determined in Compellent Storage Center.  The following diagram shows 2 WWN’s of the physical ports that are connected to one switch configured as domain 1.




  6. The WWN’s of front end virtual ports can be determined in Compellent Storage Center.  The following diagram shows 2 WWN’s of the virtual ports that are connected to the one switch configured as domain 1.




  7. As an example, the WWN’s of QLogic HBA’s can be determined by the following command.
    # cat /sys/class/scsi_host/host5/device/fc_host\:host5/port_name
    0x21000024ff27236a
  8. The following diagrams illustrate the zones created per step 4.  In this example, there’s a two-node cluster connected to dual Compellent storage controllers for high availability.




  9. Add all zones in the zone config and active the zone config.
  10. Reboot the host servers.
  11. Follow the instructions in the wiki article "How do I configure host access to my Compellent volumes?" to map volumes to host servers.
