IBM刀片服务器管理模块恢复出厂默认值实战

IBM官方文档如下：

Resetting the management module back to factory defaults

The BladeCenter management module has a reset button with which you can reset the module and return it to the factory defaults. This reset button is below the management module connectors, near the MAC address.Use a straightened paper clip or a similar item to access it. The reset button has two uses:

Reset the network configuration: Press and hold the reset button for 3 seconds or less.

Reset the entire management module (including user IDs and passwords) to the factory defaults. This requires a sequence of presses and releases:

a.   Press and hold the reset button for 5 seconds.

b.   Release the button and wait 5 seconds.

c.   Press and hold the button for another 10 seconds.

Note that this sequence should be as precise as possible to ensure success: 5 in, 5 out, 10 in. After you do a full factory defaults reset in this way, the default user ID and password will be in effect: USERID (all caps) and PASSW0RD (a zero, not the letter O).

After the network configuration has been reset, you can access the Web interface to reconfigure it. To do this, you will need to know the management module's IP address. This can be done as follows:

The management module defaults to using DHCP. The host name will be MMxxxxxxx, where xxxxxxx is the MAC address of the management module. This number is printed below the reset button.

If no DHCP server is found, the management module uses a default IP address of 192.168.70.125 with subnet mask 255.255.255.0. The host name will be MMxxxxxxx.

实际操作：

1按住reset 3秒会发现管理模块会重启，但是网络依然没有恢复

2按住reset 5秒，放开5秒，在按5秒，依然没有恢复到出厂默认值

昨天折腾了一天问题依旧，昨天将刀片关机断电，今天重新加电，发现竟然恢复了出厂默认值，无言了。

总结：第一 按照IBM官方文档操作，第二，断电在加电重启。
