Use the Solaris BIOS Update Utility or the Linux BIOS Update Utility to implement the updates. For more information, see the Sun Netra CT 900 Server Product Notes (819-1180).

4.8Secondary BIOS Image

The Sun Netra CP3220 blade server provides dual 1-Mbyte BIOS chips that support redundant BIOS images for increased reliability. The default chip (page 0) acts as the primary BIOS chip and is automatically selected for update during a firmware upgrade. The secondary BIOS chip (page 1) retains the original BIOS image, and can be used through manual configuration in the unlikely case where the primary BIOS becomes corrupt.

4.9Use the Secondary BIOS Image

If the primary BIOS becomes unbootable, use the secondary BIOS to boot the blade server:

1.Log into the Shelf Manager.

2.To select the secondary BIOS image, type:

#clia sendcmd 96 2e 81 00 00 2a 01
