Infortrend storage array configuration for PDB RACs

Each disk array supposed to be used with RAC installation should be configured in the following way:

  1. Go to the proper head node. Although there are 2 head nodes per each bunch of hardware, only one of them can be use to connect through console to each itstorXYZ disk array:
           lxc2r004.cern.ch: itstor301 -> itstor330
           lxc1r009.cern.ch: itstor401 -> itstor415
           lxc2r009.cern.ch: itstor416 -> itstor430
  2. Connect through console to the node being configured:
         console itstorXYZ
  3. Change disk array's IP address to 192.168.X.1YZ. Do not restart the controller:
         Terminal -> view and edit Configuration parameters -> Communication Parameters 
                      -> Internet Protocol (TCP/IP) -> lan0 -> Set IP Address
    8. Restart the controller
         Terminal -> system Functions -> Reset controller
  4. Connect with ftp to the disk array and upload the 'agent.ini' file. In order to connect use the IP address set above:
         ftp 192.168.X.1YZ
         [user=root pass=<cr>(empty) ]
         cd /cfg
         put agent.ini
  5. Restart the controller one more time.

Manual configuration of the array, it is now scripted - listed here for reference

4. Change the optimization mode to Random I/O:
     Terminal -> view and edit Configuration parameters -> Caching Parameters
     then chose 'Optimization for Sequential I/O' position in the menu and 'Yes' afterwards.
  1. Unmap host luns from both channels if they are mapped:
         Terminal -> vew and edit Host luns -> CHL 0/CHL 1 
  2. Delete all existing logical drives otherwise the cache optimization change will not take effect.
  3. Change ID of both channels to 'YZ'.
         Terminal -> vew and edit channelS
         then delete exisiting and add new channel IDs for both hosts (first 2 entries in the displayed table)
    10. Set date, time and timezone
         Terminal -> view and edit Configuration parameters -> Controller Parameters 
                      -> Set Controller Date and Time
    * Configure logical drives first, then partition first logical drive.
    • each logical drive should consist of one physical disk with NORAID.
      • note is needed to commit changes in some menus instead of
      • in particular do not wait after the message LD in creation (press to continue)
    • first logical drive should be partitioned into 2 partitions. First partition should be 1024 MB, second partition, the rest of the disk.
  • Map host LUNs on both channels.
    • first partition of the first logical drive should be mapped as lun number 0
    • second partition of the first logical drive should be mapped as lun number 1
    • each subsequent logical drive should be mapped as a subsequent lun.
    • repeat the operation on the other channel (mappings on both channels should be identical)
    • double check: LUN N should be mapped with LD N-1 (except for LUN 0)
