This is normal.Updating Firmware in a Redundant CMC ConfigurationNOTE: In redundant CMC configuration, care must be taken to update CMCfirmware on both modules. Failure to do so may cause unexpected behavior duringa CMC failover or failback. Use the following procedure for redundant CMCdeployments:1 Locate the secondary or standby CMC by using the RACADM getsysinfocommand, or by using the Chassis Summary page in the Web-basedinterface. Visually, the status indicator will be solid blue on the primary oractive CMC module and off on the standby or secondary CMC (seeFigure 1-9).2 Update the firmware on the standby CMC first. See "Updating the CMCFirmware Using the Web-based Interface" on page 30 or "Updating theCMC Firmware Using RACADM" on page 31.3 Verify that the secondary or standby CMC’s firmware is at the requestedlevel with the getsysinfo command or through the Web-based interface.4 After the standby CMC has rebooted, update the firmware on the active orprimary CMC. Please allow 10 minutes for the standby CMC to boot.See "Updating the CMC Firmware Using the Web-based Interface" onpage 30 or "Updating the CMC Firmware Using RACADM" on page 31.
