Display the high-availability interconnect connection status

Availability: This command is available to cluster administrators at the advanced privilege level.

Description

The system ha interconnect status show command displays the high-availability interconnect connection status. Connection status information displayed by this command varies by controller model. For nodes with two HA interconnect links over the backplane or connected externally, this command displays the following information:

  • Node

  • Link status on the first port

  • Link status on the second port

  • Is the link on first port active?

  • Is the link on second port active?

  • Interconnect RDMA status

For nodes with a single HA interconnect link, this command displays following the information:

  • Node

  • Link status

  • Interconnect RDMA status

Running the command with the -instance or -node parameter displays detailed information about the interconnect device and its ports.

Parameters

{ [-fields <fieldname>,…​]

If you specify the -fields <fieldname>,…​ parameter, the command displays only the fields that you specify.

| [-instance ] }

Use this parameter to display all the fields for the specified node or all the nodes.

[-node {<nodename>|local}] - Node (privilege: advanced)

Use this parameter to display all the fields for the specified node.

[-link-status {up|down}] - Link Status (privilege: advanced)

Selects the nodes that match this parameter value. The value up means link is online.
