console.umbc.edu now has console entries for the mgmt interface, and serial console interfaces on all of the Sun V20z servers we currently have in production. To access the managment interface, do a 'sudo console SERVER.cmgmt'.
Please, when putting any new server on line, please make sure you can get the console by typing "console SERVERNAME" on the console server; this single-point of interface makes managing our servers much easier, and much less of a headache than trying ot figure out which random managment interface you need to connect to, and what magic incantations you need to type to get access to the console output. It also make sure our console output is logged in one place, so that when a server crashes it's easy to troubleshoot why.
[UPDATE]
Also have the consoles working for the X4100s as well. Currently they're running over the serial line, however, they can be converted to use the ssh-based managment port at some point, it's just a matter of figuring out how to add the ssh keys in the totally weird CLI they've created.
