I don't know alom password, so I want reset it from Solaris. But problem is, that Solaris probably not running on this server (both indicators - system required, activity on front and back side of server is off) and I can't ping IP addresses of server (I swapped HDD to second V240 server, scan interfaces and I found some live IP addresses).
Before two weeks ago, system required indicator showed some fault. If I connected to serial console, I got SC allert message about low treshold at 3V battery, so I place new battery to motherboard and now is indicator off. So it seems ok from this side.
Does anybody some idea how to get server to usable state?
Hmm, if i recall correctly you should just be able to power on the system with the power-button while being connected to the console, this will bring you to the ALOM login prompt, but after a minute or two you should get to the ok> prompt, so you can boot/reinstall Solaris and then reset the password with the scadm command..
If this does not work, try and remove the battery you just replaced for about 2 minutes, then i think it should timeout and you should be able to reach the ok> prompt..
