Starting and Accessing LDOM

Listing all the available domains

bash-3.00# ldm ls
primary          active     -n-cv-  SP      4     1G       2.3%  14h 30m
orange1          inactive   ------          4     8G
orange2          inactive   ------          4     8G

Now both LDOMS are inactive. For activating the same, we have to bind it first.

bash-3.00# ldm bind-domain orange1

Now it can be  booted
bash-3.00# ldm start-domain orange1

Accessing the LDOM console using telnet to port 5000 ( for next domain it will be 5001 and so on)

bash-3.00# telnet 0 5001
telnet: Unable to connect to remote host: Connection refused
bash-3.00# telnet 0 5000
Connected to 0.
Escape character is '^]'.

Connecting to console "orange1" in group "orange1" ....
Press ~? for control options ..
Hostname: orange1
