Reboot and Reset Options for Superdome Partitions

Two new types of reboot and reset are provided for reconﬁguring

Superdome server partitions. These two reset methods allow you to

perform a reboot-for-reconﬁg for a partition, and allow you to put a

partition into a ready-for-reconﬁg state.

In order to modify a partition, you perform a reboot-for-reconﬁguration to

add or remove cells from the partition. The shutdown -R and reboot -R

commands support this new rebooting procedure.

You also can put a partition into a reconﬁg-reset state, which makes the

partition and all cells assigned to it inactive. When at reconﬁg-reset, all

the partition’s cells are at boot-is-blocked and do not proceed with

partition rendezvous. This also allows you to add or remove cells from

the partition from a different, remote partition within the Superdome

complex.

To reboot a partition into the reconﬁg-reset state, use the

shutdown -R -H or reboot -R -H command, the BCH interface’s

RECONFIGRESET command, or the GSP command menu’s RR command.
