Reboot for reconfiguration

During a reboot for reconfig of an nPartition, the command that you issue 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

Complex Configuration 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”).

Perform a reboot for reconfig using the following procedure:

Reboot for reconfig from Windows [Windows]

From the Windows command line use the shutdown /r command (or select the

Start >

Shut Down

action and choose Restart from the pull-down menu) to perform a reboot for

reconfig for an nPartition.

CAUTION Do not shut down Windows using Special Administration Console (SAC) restart or

shutdown commands under normal circumstances.

Issuing restart or shutdown at the SAC> prompt causes the system to restart or

shutdown immediately and can result in the loss of data.

Instead use the Windows Start menu or the shutdown command to shut down gracefully.

Step 1. Login to Windows running on the nPartition that you want to shut down.

For example, access the nPartition console and use the Windows SAC interface to start a

command prompt, from which you can issue Windows commands to shut down the

nPartition.

Step 2. Issue the shutdown /r command to shut down the Windows Server 2003 operating

system on the nPartition and reboot. You also can perform this task by selecting the

Start

> Shut Down

action and choosing Restart from the pull-down menu.

For example:

shutdown /r /t 60 /c "Reboot for reconfig."

This command initiates a Windows system shutdown-and-reboot after a timeout period

of 60 seconds. The /c option specifies a message that is broadcast to any other users of

the system.

For more details use the help shutdown command.
