Cisco C240 M4 no hdds after firmware upgrade

[astergiou]

Hello to all,

I have a problem with a Cisco C240 M4. After upgrading the firmware with HUU iso from firmware 2.0 to latest 4.1.2f controller cannot recognize any hdd.

SAS expander is showing on inventory. Server has 12x300Gb 10K drives that were working flawlessly.

Any ideas?

Did you update the HDD firmware during the HUU process?  If not, please reboot to the HUU and see if the HUU detects any drives available for firmware update.

HDDs did not need update.

Also now are not recognized, even the LEDs of the HDDs are all off..
