Starting and Accessing LDOM

Listing all the available domains

bash-3.00# ldm ls
NAME             STATE      FLAGS   CONS    VCPU  MEMORY   UTIL  UPTIME
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
Trying 0.0.0.0...
telnet: Unable to connect to remote host: Connection refused
bash-3.00# telnet 0 5000
