Single partition considerations

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.
