没有Firmware Password,怎么才能进入OK状态?
Yeah, PROM passwords can really be a pain in the neck, particularly if everyone's forgotten them or they were placed by someone who left the company but never said what the password is before (s)he left. I've purchased some systems from eBay where the PROM password was not taken off. Nimrods. I've also run into this same situation as yours numerous times at previous employers who were reconsituting old equipment that was shut off for a long time ... and of course with long-forgotten PROM passwords. Been there, dealt with that.
Can you at least get to the operating system and log in as root? If so, then I've had 100% success with:
eeprom "set-security-mode=none"
Now, granted that this is not with a Netra T1, but it's worked on every SPARC-based system that I've worked with and encountered this. But if you can't even get in as root, you're stuck on that one.
If you can't get to root but you have another Netra T1, another way is to take the operating system boot disk from the other T1 (or a really, really, REALLY similar architecture), boot from it, get to root, and do the above. The architectures have to be nearly exact, though. For example, taking a SparcStation 5 boot disk and booting it in a SparcStation 20 will not work, even though they're both sun4m.
Another option (again assuming that you have another T1) if you can't get to root on this particularl T1 is to take the PROM chip, put it in another T1 where you *can* get to root, boot, run the command above, and put the PROM chip back in the original T1.
And if that fails, I'm sure that Sun can provide you with a brand new PROM chip. I can't imagine that they'd be outrageously expensive. |
