You can boot an inactive nPartition by using any one of the following procedures:

When all cells in an nPartition are at boot-is-blocked, the nPartition is inactive. This is the case, for example, when an nPartition is held at the shutdown for reconfig state.

You can boot an nPartition past the shutdown for reconfig state to make it active by using the BO (boot) command at the service processor Command menu.

To determine whether an nPartition is in a boot-is-blocked (shutdown for reconfig) state, use the Virtual Front Panel for the nPartition to check the nPartition boot status. If all cells assigned to the nPartition are at boot-is-blocked, the nPartition is halted at the shutdown for reconfig state.

Procedure 5-45 Booting an Inactive nPartition (Service Processor)

Use the service processor Command menu BO command to boot an nPartition past the shutdown for reconfig state to make the nPartition active.

If you use the BO command to attempt to boot an nPartition that already is active, the command has no effect.

  1. Login to the service processor (MP or GSP) and enter CM to access the Command Menu.

  2. From the Command menu, enter the BO command and specify which nPartition is to be booted (released from boot-is-blocked).

    As a result of the BO command, the service processor for the complex releases the cells assigned to the selected nPartition from boot-is-blocked: the cells proceed to rendezvous to form an active nPartition, which no longer is in the shutdown for reconfig state.

    GSP:CM> BO This command boots the selected partition. # Name --- ---- 0) jules00 1) jules01 Select a partition number: 0 Do you want to boot partition number 0? (Y/[N]) y -> The selected partition will be booted. GSP:CM>

    Any of the cells assigned to the nPartition that are not configured (those with a "n" use-on-next-boot value) remain inactive at boot-is-blocked.

    When the nPartition becomes active it proceeds through the normal boot process.

  3. To exit the service processor Command Menu, enter MA to return to the service processor Main Menu.

    At the Main Menu, enter X to exit the service processor interface.

Procedure 5-46 Booting an Inactive nPartition (nPartition Commands)

You can cause an inactive nPartition to be booted (made active) by using the parmodify command with the -B option when changing the configuration of an inactive nPartition.

  1. Login to HP-UX running on any nPartition in the server complex, or login to any remote system with the Enhanced nPartition Commands (ParCLI) installed.

    When using the nPartition commands from a remote system, you can specify the -g... -h... set of options to configure a remote complex.

  2. When modifying an inactive nPartition, specify the -B option when using the /usr/sbin/parmodify command to reconfigure the inactive nPartition.

    For example, when adding or removing cells from an inactive nPartition, specifying the -B option causes the nPartition to boot (become active) immediately following the nPartition modification.

    For details refer to the parmodify(1M) manpage.
