For all of you who are using Cisco UCS C220 M3 server and Flexible Flash controller with SD card beware that there is a bug in firmware prior to 1.5(3a)<\/p>\n

The problem shows up as timeout error for FlexFlash controller. The interesting part is even though there is a problem with the FlexFlash, CIMC still is showing that overall Server Status as good:
\nOnce you log-in into CIMC you will not see that there is a problem:<\/p>\n

\"2\"<\/a>

No Errors<\/p><\/div>\n

but once you click on Storage<\/strong> tab you’ll get error message:<\/p>\n

\"\"<\/a>

Error: Unable to communicate with Flexible Flash controller: operation ffCardsGet, status ERROR_TIMEOUT<\/p><\/div>\n

In the logs you’ll see:<\/p>\n

\"\"<\/a>

BMC:FlexFlash:-: flex.c:1090:ffFirmwareInfoGet: ERROR_TIMEOUT BMC:FlexFlash:-: flex.c:2343:Failed to collect card details ERROR_TIMEOUT<\/p><\/div>\n

The problem was first noticed not in CIMC but on ESXi host as it lost connectivity to the datastore:<\/p>\n

\"Lost<\/a>

Lost connectivity to the device mpx.vmhba32:C0:T0:L0 backing the boot filesystem<\/p><\/div>\n

This is a bug on C series servers:\u00a0CSCuh33982<\/a>
\nTo fix the issue you need to upgrade the firmware to 1.5(3a) or above.
\nThe workaround is to reset FelxFlash controller but as I found out that only worked for couple weeks. So the best thing is to upgrade.<\/p>\n","protected":false},"excerpt":{"rendered":"
