sun firev210，忘了alom密码，求助

yuio654

有一台sun firev210，不知道ALOM的admin密码，现在服务器维修灯亮，操作系统起不来，想进ok下做个检测，看看到底是什么故障。crtl+pause直接到了ALOM登录界面，这个是新接手的机器。发现admin用户已经设了密码。怎么都登不进去。

现在操作系统起不来，没有办法root登陆用scadm改alom的账号密码，请问有没有办法把alom密码清除？


多谢

If the password for ALOM4v is lost or forgotten then the following password recovery steps can be taken to erase/reset the ALOM NVRAM so that a user can gain access to ALOM, set a new password and restore the NVRAM settings.


Steps to Follow

O91XZKG Internal ID use only.


Note: physical access to the system so that the power cables can be accessed and a serial connection can be made to the system is required for this procedure.

1. Make a connection to the ALOM serial management port.

2. Power cycle the system by unplugging the server's power supplies, waiting several seconds and then plugging the power supplies back in.

3. You should see the ALOM booting on the serial management console. Hit "Esc" (the Escape key) during the ALOM boot, before or at the point: "Return to Boot Monitor for Handshake"

This will cause the system to produce the message: "Return to Boot Monitor for Handshake ESC keypress detected."

4. ALOM will now enter the "ALOM boot escape menu" and the following will be displayed:

ALOM <ESC> Menu
e - Erase ALOM NVRAM.
m - Run POST Menu.
R - Reset ALOM.
r - Return to bootmon.
Your selection:
5. To clear out the existing password you must choose 'e' to erase the ALOM NVRAM. After using the 'e' option to erase the NVRAM choose the 'r' option to resume the ALOM boot. You will automatically be logged in as user 'admin' with no password and no permissions. The NVRAM settings will be reset to their factory defaults. Note that since this procedure resets the NVRAM settings to their defaults any customization (such as the ALOM network settings) will need to be recreated.

The above procedure can be adapted for the two Blade products Sun Blade T6300
Server Module and Netra CP3060 Board which also use the ALOM4v.

1. Ensure a working serial connection is made to the serial port at the front of the Blade.

2. Power cycle the board by powering off the server as per the relevant
architecture, unplug the Blade from the chassis, wait several seconds and then
plug the Blade back into the chassis.

Follow steps 3 to 5 above.

不是ALOM4V版本这方法就不灵了。
要是没过保可以报个case问问SUN有没有ALOM的维护模式。

关注，并学习一下3楼的我收藏了！谢谢

我记得Fire V210和V240好像是有一个这个特性，开机后接上串口，不要输入任何东西，大概1-3分钟后，会自动转到OK下。这个起码我V240是可以的。
LZ可以试试看。

9楼说的对，你可以在ALOM自检结束后直接进入OBP自检方式。
根据我的经验是你在连接上电源以后马上按开机按钮，一般就可以不让你login到ALOM
在ALOM自检后直接显示自检信息并进到OK。
