Installation guide

modules) to each partition and spawns a console for each secondary
partition as follows:
1. Set the lp_count EV to the number of partitions. For example, to
enable two partitions:
P00>>>set lp_count 2
2. Initialize partition 0:
P00>>>init
Configuration information (as previously described) will display on the
primary console screen, followed by the console prompt; P00>>>.
3. Initialize all secondary partitions.
P00>>>lpinit
On the primary console a series of partition configuration messages will be
displayed. including the starting address of physical memory for each
partition. Record these addresses so you can determine if a kernel rebuild
is needed in the event of a memory configuration change.
The following is a sample partition configuration display:
Partition 0: Primary CPU = 0
Partition 1: Primary CPU = 4
Partition 0: Memory Base = 000000000 Size = 080000000
Partition 1: Memory Base = 080000000 Size = 040000000
No Shared Memory
LP Configuration Tree = 128000
starting cpu 4 in partition 1 at address 040010001
starting cpu 5 in partition 1 at address 040010001
starting cpu 6 in partition 1 at address 040010001
starting cpu 7 in partition 1 at address 040010001
For each secondary partition configured, information will be displayed on
the secondary console screens, followed by a console prompt such as
P04>>>. Note that there will be a 20 second delay after the lpinit
command before the secondary consoles display their configuration
information.
If the interleave EV is incorrectly set, the console will display the
following error message:
Insufficient memory interleave sets to partition system.
Issue command "set interleave none" then reset system.
To recover from this error, enter the following commands:
P00>>>set interleave none
P00>>>set lp_count 0
P00>>>init
