Using the CMC Web Interface 151
Managing Firmware
This section describes how to use the Web interface to update firmware. The
following components can be updated using the GUI or RACADM
commands:
• CMC - primary and standby.
•iKVM
• iDRAC (boot-block mode only)
• IOM infrastructure devices
When you update firmware, there is a recommended process to follow that
can prevent a loss of service if the update fails. See "Installing or Updating the
CMC Firmware" on page 52 for guidelines to follow before you use the
instructions in this section.
Viewing the Current Firmware Versions
The Updatable Components page displays the current version of the iKVM
firmware, primary CMC firmware, (if applicable) the standby CMC firmware,
the iDRAC firmware, and the IOM infrastructure device firmware. Clicking
on either the device name or the firmware version will display a Device
Update page for that particular device.
The Device Update page displays only one device at a time, except in the case
of the CMC where both the standby and active CMCs are displayed if both
are updatable. Only the standby and active CMC can be updated at the same
time with the same action from the Web interface; all other devices (IOMs or
servers) must be updated one at a time. To update multiple servers and
IOMs, refer to "fwupdate" on page 329 for information on the fwupdate
command.
If the chassis contains a server whose iDRAC is in recovery mode or if the
CMC detects that an iDRAC has corrupted firmware, the iDRAC is also
listed on the Updatable Components page. See "Recovering iDRAC
Firmware Using the CMC" on page 157 for the steps to recover iDRAC
firmware using the CMC.
