I recently purchased a (gently) used Sun Fire v250 for use as a workstation. The machine had a graphics card installed by a previous owner, but I accidentally reset the factory defaults on the SCC (I was having a boot problem, and apparently a brain problem).
My question is, how do I connect over serial to make the default boot up options 'screen' instead of 'ttya'? I know from the oracle docs that I need a specific type of serial cable, but I'm unsure where exactly I can go about finding this. Also, once I get the cable what software (for *NIX or windows) can I use to reset the SCC?
If you laptop/desktop does not have a serial get a usb to serial converter as well.
If you have a linux desk OS then it is possible to connect to a serial connection ... from solaris you would use tip .... from linux typically use 'cu' (built it) ... if I remember correctly.
Or use recent versions of PuTTY from windows. ... which can also be configured for serial.
In addition to that first reply, here's the link to the documentation for your V250:
You may want to glance at Chapter 3 of the V250 Admin Guide
for a start with the ALOM port.
Glancing at your first post...
If you inadvertantly changed the OBP settings, you could just SSH across your network to a running Solaris, then once you've logged in as your normal user you <tt>su</tt> to root and then use the <tt>eeprom</tt> command to change the output-device back to screen. A reboot of the V250 to set the changes, and you'd be back as before.
Thanks! I'll try and round up a cisco console cable and connect that way. It's probably worth mentioning that the system doesn't currently have an operating system (or, at least, one that boots automatically and has SSH) I've monitored my router, and the mac for the sun never shows up.
