Performing a Reboot-for-Reconﬁg for a Partition

When you perform a reboot-for-reconﬁg of a partition, the HP-UX

command that you issue (shutdown or reboot) does the following tasks:

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

partition, including any inactive cells.

• Reconﬁgures the partition if necessary (adds or removes cells).

• Boots all cells in the partition.

You should perform a reboot-for-reconﬁg of a partition whenever you add

or remove cells from the partition, and whenever you need to allow an

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

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

HP-UX Use the following procedure to perform a reboot-for-reconﬁg for a

partition.

Step 1. Log in to HP-UX running on the partition.

You can log in to HP-UX on the partition either by directly connecting

with telnet or rlogin, or by logging in to its complex’s GSP and

accessing the partition’s console. Connecting through the GSP allows you

to maintain partition console access after HP-UX has shut down.

Step 2. Issue the shutdown or reboot command and specify the -R option.

The shutdown -R and reboot -R commands shut down HP-UX, reboot

all cells assigned to the partition, performany partition reconﬁgurations,

and boot all cells.

NOTE The reboot command does not invoke the shutdown scripts associated

with subsystems. The shutdown command invokes the scripts and

terminates all running processes in an orderly and cautious manner.

You can perform this task using HP-UX commands.
