Performing a Reboot for Reconﬁg for an

nPartition

During a reboot for reconﬁg of an nPartition, the HP-UX command

that you issue (shutdown -R) performs the following tasks:

1. Shuts down HP-UX and resets all cells that are assigned to the

nPartition, including any inactive cells.

2. Reconﬁgures the nPartition if necessary (adds or removes cells).

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.

You should perform a reboot for reconﬁg of an nPartition whenever you

add or remove cells from the nPartition, and whenever you need to allow

an inactive cell to join the nPartition (such as after changing a cell’s

use-on-next-boot value from “n” to “y”).

Performing a Reboot for Reconﬁg [HP-UX]

This procedure (shutdown -R command) performs a reboot for reconﬁg

for an nPartition.

Step 1. Login to HP-UX running on the nPartition.

You can login to HP-UX on the nPartition either by directly connecting

(with the telnet or rlogin commands) or by logging in to its complex’s

service processor (GSP or MP) and using the Console menu to access the

nPartition’s console.

Step 2. Issue the shutdown -R command to perform a reboot for reconﬁg of the

nPartition.

The shutdown -R command shuts down HP-UX, reboot all cells assigned

to the nPartition, performs any nPartition reconﬁgurations, and boot all

cells that have “y” use-on-next-boot values.
