During a recent upgrade of Cisco B200 M4 blades I got the following 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 2: Click Yes to reset the FlexFlash controller
Step 3: Click Ok on reset notification
During a recent UCS firmware upgrade I had quite a few blades show up with the error “CIMC did not detect storage”. Within UCSM I could see that the blade had a critical alert. It initially started after I upgraded UCS Manager firmware as documents in a previous post I wrote about UCS Firmware Upgrades. I did some searching around to find what may be causing the issue and the best answer I could find was to from the Cisco community forums to disassociate the blade, decommission and reseat within the chassis. I later spoke to a Cisco engineer and he advised of the same steps but that it was also possible to do without reseating the blade. This also looks like its a problem when upgrading from 2.2(1d) to other versions of UCSM but I haven’t been able to validate if it’s only that version or if it also affects others.
The full error I saw was for code F1004 and for Controller 1 on server 2/1 is inoperable. Reason: CIMC did not detect storage
Within UCSM I could see there was an issue with the Blade
Before proceeding with the upgrade of the FIs, IOMs and Blades themselves I wanted to clear any alerts within UCSM, particularly critical alerts. The steps I followed to bring the blade back online were to go to the blade and select Server Maintenance
