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, ssccn3-dom2 and ssccn3-dom3 are Root Domains. The other domains are dedicated domains.
# ldm list-io | grep BUS NAME TYPE BUS DOMAIN STATUS pci_32 BUS pci_32 primary pci_33 BUS pci_33 primary pci_34 BUS pci_34 primary pci_35 BUS pci_35 primary pci_36 BUS pci_36 ssccn3-dom2 IOV pci_37 BUS pci_37 ssccn3-dom2 IOV pci_38 BUS pci_38 ssccn3-dom2 IOV pci_39 BUS pci_39 ssccn3-dom2 IOV pci_40 BUS pci_40 ssccn3-dom1 pci_41 BUS pci_41 ssccn3-dom1 pci_42 BUS pci_42 ssccn3-dom1 pci_43 BUS pci_43 ssccn3-dom1 pci_44 BUS pci_44 ssccn3-dom3 IOV pci_45 BUS pci_45 ssccn3-dom3 IOV pci_46 BUS pci_46 ssccn3-dom3 IOV pci_47 BUS pci_47 ssccn3-dom3 IOV
In this example, ssccn3-dom2 and ssccn3-dom3 are Root Domains (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.
# ldm list NAME STATE FLAGS CONS VCPU MEMORY UTIL NORM UPTIME primary active -n-cv- UART 192 2095872M 0.1% 0.1% 12h 28m ssccn3-dom1 active -n---- 5001 192 2T 0.1% 0.1% 12h 25m ssccn3-dom2 active -n---- 5002 8 16G 0.1% 0.1% 2d 23h 34m ssccn3-dom3 active -n--v- 5003 16 32G 0.1% 0.1% 2d 23h 34m
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 memory repository.
# ldm list-devices -p core | grep cid | wc -l

# ldm list-devices memory
