Step 4: Set the Environment Variables  



Configure the primary console for instance 0.

CPU0 is the primary for instance 0.

Create the Galaxy environment variables. For descriptions of the Galaxy environment variables and common values for them, see Creating an OpenVMS Galaxy on an AlphaServer 8400 System.

The following example is for an AlphaServer 4100 with three CPUs and 512 MB of memory divided into 256 MB + 192 MB + 64 MB:

P00>>> create -nv lp_count            2
P00>>> create -nv lp_cpu_mask0        1
P00>>> create -nv lp_cpu_mask1        6
P00>>> create -nv lp_io_mask0         10
P00>>> create -nv lp_io_mask1         20
P00>>> create -nv lp_mem_size0        10000000
P00>>> create -nv lp_mem_size1        c000000
P00>>> create -nv lp_shared_mem_size  4000000
P00>>> set auto_action halt
If you have four CPUs and you want to assign all secondary CPUs to instance 1, the LP_CPU_MASK1 variable will be E. If you split the CPUs between both instances, CPU 0 must be the primary for instance 0, and CPU 1 must be the primary CPU for instance 1.

The MEM_SIZE variables depend on your configuration and how you want to split it up.

You must set the console environment variable AUTO_ACTION to HALT. This ensures that the system does not boot and that you are able to enter the Galaxy command.
