Step 5: Initialize the System and Start the Console Devices  



  1. Initialize the system and start the Galaxy firmware by entering the following commands:
    P00>>> init
    P00>>> galaxy
    After the self-test completes, the Galaxy command starts the console on instance 1.

    The first time that the Galaxy starts, it might display several messages like the following:
    CPU0 would not join
    IOD0 and IOD1 did not pass the power-up self-test
    This happens because there are two sets of environment variables, and the Galaxy variables are not present initially on instance 1.

    Note that when the I/O bus is divided between the two Galaxy partitions, the port letter of a device might change. For example, a disk designated as DKC300 when the AlphaServer 4100 is a single system could become DKA300 when it is configured as partition 0 of the OpenVMS Galaxy.
  2. Configure the console for instance 1:
    P01>>> create -nv lp_cpu_mask0        1
    P01>>> create -nv lp_cpu_mask1        6
    P01>>> create -nv lp_io_mask0         10
    P01>>> create -nv lp_io_mask1         20
    P01>>> create -nv lp_mem_size0        10000000
    P01>>> create -nv lp_mem_size1        c000000
    P01>>> create -nv lp_count       2
    P01>>> create -nv lp_shared_mem_size  4000000
    P01>>> set auto_action halt
  3. Initialize the system and restart the Galaxy firmware by entering the following command:
    P00>>> init
    When the console displays the following confirmation prompt, type Y:
    Do you REALLY want to reset the Galaxy (Y/N)
  4. Configure the system root, boot device, and other related variables.

    The following example settings are from an OpenVMS Engineering system. Change these variables to meet the needs of your own environment.
    P00>>> set boot_osflags	12,0
    P00>>> set bootdef_dev	dka0
    P00>>> set boot_reset	off             !!! must be OFF !!!
    P00>>> set ewa0_mode	twisted
     
    P01>>> set boot_osflags	11,0
    P01>>> set bootdef_dev	dkb200
    P01>>> set boot_reset	off             !!! must be OFF !!!
    P01>>> set ewa0_mode	twisted
  5. Boot instance 1 as follows:
    P01>>> boot
    Once instance 1 is booted, log in to the system account and edit the SYS$SYSTEM:MODPARAMS.DAT file to include the following line:
    GALAXY=1
    Confirm that the lines for the SCS node and SCS system ID are correct. Run AUTOGEN as follows to configure instance 1 as a Galaxy member, and leave the system halted:
    $ @SYS$UPDATE:AUTOGEN GETDATA SHUTDOWN INITIAL
  6. Boot instance 0 as follows:
    P00>>> boot
    Once instance 0 is booted, log in to the system account and edit the SYS$SYSTEM:MODPARAMS.DAT file to include the following line:
    Add the line GALAXY=1
    Confirm that the lines for the SCS node and SCS system ID are correct. Run AUTOGEN as follows to configure instance 0 as a Galaxy member, and leave the system halted:
    $ @SYS$UPDATE:AUTOGEN GETDATA SHUTDOWN INITIAL
  7. Prepare the Galaxy to come up automatically upon initialization or power cycle of the system. Set the AUTO_ACTION environment variable on both instances to RESTART:
    P00>>> set auto_action restart
     
    P01>>> set auto_action restart
  8. Initialize the Galaxy again by entering the following command at the primary console:
    P00>>> init
    When the console displays the following confirmation prompt, type Y:
    Do you REALLY want to reset the Galaxy (Y/N)
    Alternatively, you could power-cycle your system, and the Galaxy with both instances should bootstrap automatically.

Congratulations! You have created an OpenVMS Galaxy.
