Cloud infrastructure: Factory Default Configuration and Disabling Logical Domains

Wednesday, June 3, 2020

How to Remove All Guest Domains

Stop all domains by using the -a option.
```
primary# ldm stop-domain -a
```
Unbind all domains except for the primary domain.
```
primary# ldm unbind-domain ldom
```
Note - You might be unable to unbind an I/O domain if it is providing services required by the control domain. In this situation, skip this step.
Destroy all domains except for the primary domain.
```
primary# ldm remove-domain -a
```

List all the logical domain configurations that are stored on the service processor (SP).
```
primary# ldm list-config
```
Remove all configurations (config-name) previously saved to the SP except for the factory-default configuration.
Use the following command for each such configuration:
```
primary# ldm rm-config config-name
```
After you remove all the configurations previously saved to the SP, the factory-default domain is the next domain to use when the control domain (primary) is rebooted.

Select the factory default configuration.
```
primary# ldm set-config factory-default
```
Stop the control domain.
```
primary# shutdown -i1 -g0 -y
```
Perform a power cycle of the system to load the factory default configuration.
```
-> stop /SYS
-> start /SYS
```

Disable the Logical Domains Manager from the control domain.
```
primary# svcadm disable ldmd
```
Note - Disabling the Logical Domains Manager does not stop any running domains, but does disable the ability to create a new domains, change the configuration of existing domains, or monitor the state of the domains.
