Recovering the Corrupt BIOS on a Blade Server

Sometimes, an issue with a server might require you to recover the corrupted BIOS. This procedure is not part of the normal maintenance of a server. After you recover the BIOS, the server boots with the running version of the firmware for that server. This radio button might dim if the BIOS does not require recovery or the option is not available for a particular server.

Before you begin


Important

Remove all attached or mapped USB storage from a server before you attempt to recover the corrupt BIOS on that server. If an external USB drive is attached or mapped from vMedia to the server, BIOS recovery fails.

Procedure

In the Navigation pane, click Equipment.

Step 2

Expand Equipment > Chassis > Chassis Number > Servers.

Step 3

Choose the server for which you want to recover the BIOS.

Step 4

In the Work pane, click the General tab.
