This procedure describes how to display a compute node domain configuration using a series of ldm commands.
Root Domains are identified by IOV in the STATUS column.
In this example, ssccn2-dom5 is a Root Domain. The other domains are dedicated domains.
# ldm list-io | grep BUS NAME TYPE BUS DOMAIN STATUS pci_0 BUS pci_0 primary pci_1 BUS pci_1 primary pci_2 BUS pci_2 primary pci_3 BUS pci_3 primary pci_4 BUS pci_4 ssccn2-dom1 pci_5 BUS pci_5 ssccn2-dom1 pci_6 BUS pci_6 ssccn2-dom2 pci_7 BUS pci_7 ssccn2-dom2 pci_8 BUS pci_8 ssccn2-dom3 pci_9 BUS pci_9 ssccn2-dom3 pci_10 BUS pci_10 ssccn2-dom4 pci_11 BUS pci_11 ssccn2-dom4 pci_12 BUS pci_12 ssccn2-dom5IOV pci_13 BUS pci_13 ssccn2-dom5IOV pci_14 BUS pci_14 ssccn2-dom5IOV pci_15 BUS pci_15 ssccn2-dom5IOV
In this example, ssccn2-dom5 is a Root Domain (from Step 2). The resources listed for Root Domains only represent the resources that are reserved for the Root Domain itself. Parked resources are not displayed.

Based on your SuperCluster model, use one of these specifications to convert socket, core, and VCPU values.
Use these specifications for SuperCluster T5-8.
1 socket = 16 cores
1 core = 8 VCPUs
Use these specifications for SuperCluster M6-32.
1 socket = 12 cores
1 core = 8 VCPUs
In this example, the first command line reports the number of cores in the logical CPU repository. The second command line reports the amount of memory in the logical memory repository.
# ldm list-devices -p core | grep cid | wc -l
28
# ldm list-devices memory
