Host Channel Adapter (HCA)

Host Channel Adapters (HCAs) provide a managed system with port connections to other devices. That port can be connected to another HCA, a target device, or a switch that redirects the data coming in on one of its ports out to a device attached to another of its ports.

You can show a list of the HCAs for the managed system. You can select an HCA from the list to display the current partition usage for the HCA.

From this task you can display the following:

The physical location of each HCA on the managed system.
The number of globally unique identifiers (GUIDs) that are in use on each HCA.
The number of GUIDs on each HCA that are available to be assigned to logical partitions.
HMC management status. HCAs that are unable to be managed by an HMC are in an error state.
The logical partition usage for a selected HCA.
