How to Start a Domain

This procedure describes how to start an existing bound domain. If a domain with the specified domain name does not exist or is not already bound, this operation fails.

Verify that the domain-name domain exists and is bound.
```
# ldm list domain-name
```

Identify domain-name in ldomTable.

# snmpwalk -v1 -c public localhost SUN-LDOM-MIB::ldomTable

Start the domain-name domain.
Use the snmpset command to start the domain by setting a value of 1 to the ldomAdminState property. n specifies the domain to start.
```
# snmpset -v version -c community-string hostname \
SUN-LDOM-MIB::ldomTable.1.ldomAdminState.n = 1
```

Verify that the domain-name domain is active by using one of the following commands:

```
# ldm list domain-name
```

# snmpget -v version -c community-string hostname SUN-LDOM-MIB::ldomOperState.n

Example 17-5 Starting a Guest Domain

This example verifies that the LdomMibTest_1 domain exists and is bound before setting the ldomAdminState property to 1. Finally, the ldm list LdomMibTest_1 command verifies that the LdomMibTest_1 domain is active.

# ldm list LdomMibTest_1
# snmpset -v1 -c private localhost SUN-LDOM-MIB::ldomTable.1.ldomAdminState.2 = 1
# ldm list LdomMibTest_1

You can also use the snmpget command to retrieve the LdomMibTest_1 domain's state instead of using the ldm list command.

# snmpget -v1 -c public localhost SUN-LDOM-MIB::ldomOperState.2

Note that if the domain is inactive when you use snmpset to start the domain, the domain is first bound and then started.
