If you have a cell based system and you modify or create a npar, you need to do a reboot for reconfig to make the configuration valid.

Hi,
you should read this guide, if you want any more details:

http://h20000.www2.hp.com/bizsupport/TechSupport/CoreRedirect.jsp?redirectReason=DocIndexPDF&prodSeriesId=322811&targetPage=http%3A%2F%2Fbizsupport2.austin.hp.com%2Fbc%2Fdocs%2Fsupport%2FSupportManual%2Fc01868281%2Fc01868281.pdf

As being said, it is being used to confirm the reconfiguration of nPartitions: For example, adding/removing a cell to/from an nPartition ; Deleting whole nPartition ; Creating an nPartition.

I am not sure of a difference between the two terms as you state them.

Another thing that "reboot for reconfig" does is places the cells into a Boot Is Blocked status. That is, the cells are reset, allowed to pass POST, but are stopped just prior to joining the partition.

This is done a couple of ways:
From the MP:
MP:CM> RR

From the OS:
-RH option for shutdown or reboot.

-Bob

Hi,

Here is some info on Reboot for Reconfig. During a reboot for reconfig of an nPartition, it performs the following tasks:

1. Shuts down the operating system and resets all cells that are assigned to the nPartition, including any inactive cells.

2.Reconfigures the nPartition if necessary (if there is a pending change to the Stable ComplexConfiguration Data, it occurs during the reboot for reconfig).

3. Boots all cells in the nPartition. Any cells with a "n" use-on-next-boot value remain inactive at BIB, and all other cells can rendezvous to form the nPartition.

Perform a reboot for reconfig of an nPartition whenever you add cells or remove active cells from the nPartition, and whenever you need to allow an inactive cell to join the nPartition (such as after changing a cell use-on-next-boot value from "n" to "y").

However, I havent come acorss Ready for Reconfig !

I think the term is seen differently on different system types. I would bet you can safely assume that they refer to the same thing.
