The following considerations apply to compute nodes in
a multi-node complex that operate as a single-hardware partition:
- The single partition uses the UEFI settings (set through the Setup
utility) defined for the primary compute node.
- If you update firmware using UpdateXpress System Packs (UXSP),
when you upgrade the firmware for the compute nodes operating as a
single partition, you only have to upgrade the primary compute node.
The firmware on the secondary compute nodes is automatically updated.
- The primary compute node has access to the hard disk drives and
SSDs on the secondary compute nodes.
- Use the UEFI multi-node drive sharing setting to combine the drives
on the primary compute node with the drives on the secondary compute
nodes to form a single RAID array. RAID arrays can be formed only
using the drives in individual compute nodes.
- The primary compute node has access to any I/O expansion adapters
that are installed in the secondary compute nodes. However, the I/O
expansion adapters in the secondary compute nodes cannot be used for
a Serial Over LAN connection.
- When you press the power-control button on any compute node in
a single partition (controlled by one operating system), all compute
nodes in the single partition will be turned on or turned off.
