Requirements for Booting Partitions

Before you boot a partition, HP recommends that the partition meet the

requirements listed here.

• All partitions within a Superdome complex must conform to an

HP-recommended complex conﬁguration.

See Chapter 4, “Conﬁguring and Managing Superdome Partitions,”

on page 113 for partition requirements and guidelines.

• All the partition’s cells that are designated to be used during the

current partition boot should be powered on.

Any cells not powered on will not be available to the partition. During

partition rendezvous, the partition will wait up to 10 minutes for all

designated cells (those set to be used on the current boot) to report in

to the partition and rendezvous.

The partition does not wait to rendezvous with assigned cells that are

designated to not be used for the current boot (inactive cells).

• All I/O devices for the partition should be powered on.

• All complex proﬁle information for the partition must be coherent.

This means all cells assigned to the partition must have identical

complex proﬁle information (Partition Conﬁguration Data). This is

managed by the partition conﬁguration tools, described in Chapter 4,

“Conﬁguring and Managing Superdome Partitions,” on page 113.

After you add or remove a cell from a partition, you must perform a

reboot-for-reconﬁg of the partition to synchronize the complex proﬁle

data throughout the partition; this also causes all the partition’s cells

to boot and allows the assigned and active cells to go through the

partition rendezvous procedure.

For details on conﬁguring partitions see Chapter 4, “Conﬁguring and

Managing Superdome Partitions,” on page 113. See also Chapter 3,

“Managing the Overall Complex,” on page 57 for details about powering

on and powering off system components.
