An Overview of nPartition Boot and Reset
Checklist and Guidelines for Booting nPartitions
HP System Partitions Guide: Administration for nPartitions, rev 5.1 185
By configuring HAA and ALT boot device paths, you establish
additional bootable devices that provide redundancy in case the PRI
device fails.
Also configure the path flags for the boot paths, to allow the HAA
device to boot automatically if the device at the PRI path cannot
boot.
❏ Ensure that the core I/O, PRI boot device, and network card(s) all are
connected to same cell (the core cell).
This configuration ensures that the core cell is directly connected to
the I/O required for booting the nPartition and providing network
connections. Having such a configuration eliminates the requirement
for multiple cells to be functional to provide basic nPartition services.
❏ Have multiple core cells available within each nPartition, if possible.
In order to have multiple core cell choices, the nPartition must have
at least two cells, each connected to an I/O chassis and core I/O.
Having such a configuration provides redundancy and potentially
improved system availability. If one core cell has a failure or
otherwise cannot serve as the active core cell, the second
core-capable cell can serve as the active core cell.
Disregard this guideline if configuring multiple nPartitions in an HP
rp7410 or HP rp8400 server complex. HP rp7410 servers and
HP rp8400 servers have up to two core-capable cells only, so
following this guideline would require having only one nPartition in
the server complex.
