Creating a Genesis Partition
When you create a Genesis Partition, you establish a one-cell nPartition
on the server complex. The Genesis Partition replaces all other
nPartitions, and once created it is the only nPartition in the server.
The only way to create a Genesis Partition is to use the service processor
Command menu’s CC command on the server complex.
Genesis Partition Creation [Service Processor]
The following procedure (service processor Command menu, CC
command, G option) creates a Genesis Partition on an HP nPartition
server.
As a result of this procedure, all existing nPartitions are destroyed and
are replaced with a single, one-cell nPartition (the Genesis Partition).
You can revert to the previous nPartition configuration—if any existed
before you created the Genesis Partition—by using the CC command’s L
option to restore the last configuration.
Step 1. Save all current nPartition configuration details, if any nPartitions are
configured in the complex.
Saving the current nPartition information provides you the details you
would need to re-create all nPartitions as they currently exist.
Use the parstatus -V -p # HP-UX command (or an equivalent parmgr
procedure) to save configuration details about each nPartition.
For each nPartition, enter the parstatus -V -p # command to display
detailed information about the partition number (-p # ) specified.
Step 2. Determine which cell will be configured as the Genesis Partition.
The cell must be connected to an I/O chassis. The I/O chassis must have a
core I/O card installed, and it should have a bootable HP-UX disk (or a
method for installing HP-UX and a disk onto which it can be installed).
Step 3. Ensure that all nPartitions within the complex are in the
ready for reconfig (inactive) state.
