Listing Domain Resources

This section shows the syntax usage for the ldm subcommands, defines some output terms, such as flags and utilization statistics, and provides examples that are similar to what you actually see as output.

Machine-Readable Output

If you are creating scripts that use ldm list command output, always use the -p option to produce the machine-readable form of the output. See Generate a Parseable, Machine-Readable List (-p) for more information.

Show Syntax Usage for `ldm` Subcommands

Look at syntax usage for all ldm subcommands.
```
primary# ldm --help
```
For more information about the ldm subcommands, see the ldm(1M) man page.

Flag Definitions

The following flags can be shown in the output for a domain (ldm list). If you use the long, parseable options (-l -p) for the command, the flags are spelled out; for example, flags=normal,control,vio-service. If not, you see the letter abbreviation; for example -n-cv-. The list flag values are position dependent. Following are the values that can appear in each of the six columns from left to right.

Column 1

s starting or stopping
- placeholder

Column 2

n normal
t transition

Column 3

d delayed reconfiguration
r memory dynamic reconfiguration (DR)
- placeholder

Column 4

c control domain
- placeholder

Column 5

v virtual I/O service domain
- placeholder

Column 6

s source domain in a migration
t target domain in a migration
e error occurred during a migration
- placeholder

Utilization Statistic Definition

The per virtual CPU utilization statistic (UTIL) is shown on the long (-l) option of the ldm list command. The statistic is the percentage of time that the virtual CPU spent executing on behalf of the guest operating system. A virtual CPU is considered to be executing on behalf of the guest operating system except when it has been yielded to the hypervisor. If the guest operating system does not yield virtual CPUs to the hypervisor, the utilization of CPUs in the guest operating system will always show as 100%.

The utilization statistic reported for a logical domain is the average of the virtual CPU utilizations for the virtual CPUs in the domain. A dash (---) in the UTIL column means that the strand is power-managed.

Viewing Various Lists

Show Software Versions (`-V`)

View the current software versions installed.
```
primary# ldm -V
```

Generate a Short List

Generate a short list for all domains.
```
primary# ldm list
```

Generate a Long List (`-l`)

Generate a long list for all domains.
```
primary# ldm list -l
```

Generate an Extended List (`-e`)

Generate an extended list of all domains.
```
primary# ldm list -e
```

Generate a Parseable, Machine-Readable List (`-p`)

Generate a parseable, machine-readable list of all domains.
```
primary# ldm list -p
```

Generate a Subset of a Long List (`-o` `format`)

Generate output as a subset of resources by entering one or more of the following format options. If you specify more than one format, delimit the items by a comma with no spaces.
```
primary# ldm list -o resource[,resource...] ldom
```
- console – Output contains virtual console (vcons) and virtual console concentrator (vcc) service
- core – Output contains information about domains that have whole cores allocated
- cpu – Output contains information about the virtual CPU (vcpu), physical CPU (pcpu), and core ID
- crypto – Cryptographic unit output contains Modular Arithmetic Unit (mau) and any other supported cryptographic unit, such as the Control Word Queue (CWQ)
- disk – Output contains virtual disk (vdisk) and virtual disk server (vds)
- domain – Output contains variables (var), host ID (hostid), domain state, flags, UUID, and software state
- memory – Output contains memory
- network – Output contains media access control (mac) address , virtual network switch (vsw), and virtual network (vnet) device
- physio – Physical input/output contains peripheral component interconnect (pci) and network interface unit (niu)
- resmgmt – Output contains dynamic resource management (DRM) policy information, indicates which policy is currently running, and lists constraints related to whole-core configuration
- serial – Output contains virtual logical domain channel (vldc) service, virtual logical domain channel client (vldcc), virtual data plane channel client (vdpcc), virtual data plane channel service (vdpcs)
- stats – Output contains statistics that are related to resource management policies
- status – Output contains status about a domain migration in progress
The following examples show various subsets of output that you can specify:
- List CPU information for the control domain
```
# ldm list -o cpu primary
```
- List domain information for a guest domain
```
# ldm list -o domain ldm2
```
- List memory and network information for a guest domain
```
# ldm list -o network,memory ldm1
```
- List DRM policy information for a guest domain
```
# ldm list -o resmgmt,stats ldm1
```

List a Variable

Show a variable and its value for a domain.

primary# ldm list-variable variable-name ldom

For example, the following command shows the value for the boot-device variable on the ldg1 domain:

primary# ldm list-variable boot-device ldg1
boot-device=/virtual-devices@100/channel-devices@200/disk@0:a

List Bindings

List the resources that are bound to a domain.
```
primary# ldm list-bindings ldom
```

List Configurations

List logical domain configurations that have been stored on the SP.

Example 10-5 Configurations List

The ldm list-config command lists the logical domain configurations that are stored on the service processor. When used with the -r option, this command lists those configurations for which autosave files exist on the control domain.

For more information about configurations, see Managing Logical Domains Configurations. For more examples, see the ldm(1M) man page.

primary# ldm list-config
factory-default
3guests
foo [next poweron]
primary
reconfig-primary

Meaning of Labels

The labels to the right of the configuration name mean the following:

[current] – Last booted configuration, only as long as it matches the currently running configuration; that is, until you initiate a reconfiguration. After the reconfiguration, the annotation changes to [next poweron].
[next poweron] – Configuration to be used at the next powercycle.

List Devices

List all server resources, bound and unbound.
```
primary# ldm list-devices -a
```

List Available Memory

List the amount of memory available to be allocated.

primary# ldm list-devices mem
MEMORY
    PA                   SIZE
    0x14e000000          2848M

List Services

List the services that are available.
```
primary# ldm list-services
```

Listing Constraints

To the Logical Domains Manager, constraints are one or more resources you want to have assigned to a particular domain. You either receive all the resources you ask to be added to a domain or you get none of them, depending upon the available resources. The list-constraints subcommand lists those resources you requested assigned to the domain.

List Constraints for One Domain

List constraints for one domain.
```
primary# ldm list-constraints ldom
```

List Constraints in XML Format

List constraints in XML format for a particular domain.
```
primary# ldm list-constraints -x ldom
```

List Constraints in a Machine-Readable Format

List constraints for all domains in a parseable format.
```
primary# ldm list-constraints -p
```
