Installing or Updating the CMC Firmware
NOTE:
During updates of CMC or iDRAC firmware on a server, some or all of the fan
units in the chassis will spin at 100%. This is normal.
Updating Firmware in a Redundant CMC Configuration
NOTE:
In redundant CMC configuration, care must be taken to update CMC
firmware on both modules. Failure to do so may cause unexpected behavior during
a CMC failover or failback. Use the following procedure for redundant CMC
deployments:
1 Locate the secondary or standby CMC by using the RACADM getsysinfo
command, or by using the Chassis Summary page in the Web-based
interface
. Visually, the status indicator will be solid blue on the primary or
active CMC module and off on the standby or secondary CMC (see
Figure 1-9).
2 Update the firmware on the standby CMC first. See "Updating the CMC
Firmware Using the Web-based Interface" on page 30 or "Updating the
CMC Firmware Using RACADM" on page 31.
3 Verify that the secondary or standby CMC’s firmware is at the requested
level with the getsysinfo command or through the Web-based interface.
4 After the standby CMC has rebooted, update the firmware on the active or
primary CMC. Please allow 10 minutes for the standby CMC to boot.
See "Updating the CMC Firmware Using the Web-based Interface" on
page 30 or "Updating the CMC Firmware Using RACADM" on page 31.
