# Associated nodes deployment behavior

##

The following describes which nodes SUM can automatically add and the order in which SUM deploys the nodes:

Onboard Administrator

  Types of associated nodes:

  - iLO

  - Virtual Connect

  - SAS Switches

  Deployment behavior:

  - Deploys the OA first and then other nodes.

Virtual Connect
  NOTE:

  If the Virtual Connect is configured in CNSA mode, SUM does not support upgrading, downgrading, or rewriting the firmware.

  Types of associated nodes:

  - Onboard Administrator

  Deployment behavior:

  - Deploys the VC first and then the OA.

FC Switch

  Types of associated nodes:

  - Partner FC Switches

  Deployment behavior:

  - Deploys to the selected switch first and then to associated switches.

6 Gb SAS BL Switches

  Types of associated nodes:

  - Onboard Administrator

  Deployment behavior:

  - Deploys to the selected switch first and then to the OA.

iLO

  Types of associated nodes:

  - Onboard Administrator

  - Server

  Deployment behavior:

  - Deploys to the iLO first and then the OA and servers.
    NOTE:

    SUM adds associated server only for iLO 4 nodes, not for iLO 5.

Server

  Types of associated nodes:

  - None

Superdome X

  Types of associated nodes:

  - None

Superdome Flex

  Types of associated nodes:

  - None

NOTE:

If you are running a mixed IPv4 and IPv6 environment, SUM might display the following issues:

- If you add an IPv6 iLO with associated nodes and the associated nodes are only configured with IPv4, SUM displays IPv6 nodes.

- SUM does not support IPv6 for SAS and FC switches.
