During a recent upgrade of Cisco B200 M4 blades I got the following error:

FlexFlash FFCH_ERROR_OLD_FIRMWARE_RUNNING
flexflash-error

I really wasn’t sure what was causing the issue but it turned out to be a known bug for M4 blades. More details can be found over on Cisco BugSearch Note: You’ll need a Cisco Login to access the site. Basically the issue affects B200 M4 blades upgraded to 2.2(4) or higher.

The workaround is actually quite easy and just needs to have the FlexFlash Controller reset. This can be done using the below steps:

Step 1: Select Equipment -> Chassis # -> Server # -> Inventory -> Storage -> Reset FlexFlash Controller

Step 3: Click Ok on reset notification
