Shows the current partition usage for the selected Host Channel Adapter (HCA).
The following columns are shown:
- Logical Partition
- The partition to which one or more Globally Unique Identifiers (GUIDs) from the selected HCA is assigned.
- GUID Index
- A number from 1 through 62 that identifies which GUID from the HCA is assigned to the logical partition.
If the GUID Index is -1, this means the GUID is no longer valid. A possible reason is that the HCA has been replaced with a new HCA with a new set of GUIDs. If so, you must reconfigure the GUID index in the partition profile, and shut down and reactivate the logical partition using the changed partition profile.- GUID
- The actual GUID that is assigned to the partition. A GUID is an eight-byte sequence of hexidecimal numbers that identifies a node. The first seven bytes of the GUID identify the HCA. All GUIDs on an HCA start with the same first seven bytes. The last byte of each GUID is formed by subtracting 1 from the GUID index and converting the result to hexidecimal.
- Capability
- The amount of resource that is allocated to the GUID from the Host Channel Adapter. Possible values in the Capability column are:
- Low
1/16 (6.25%) of the resources of the adapter are allocated to the GUID. Because the resources are not evenly divided, the maximum number of partitions that can be activated with Low is 15.- Medium
1/8 (12.5%) of the resources of the adapter are allocated to the GUID.- High
1/4 (25%) of the resources of the adapter are allocated to the GUID.- Dedicated
All (100%) of the resources of the adapter are allocated to the GUID.- HMC Managed
- Indicates whether the Hardware Management Console (HMC) is able to manage the assignment of the GUIDs. If the value is No, the adapter is in an error state that prevents the HMC from configuring the GUID allocation.
