The following are the known limitations related to FlexFlash SD cards in this release of Cisco UCS Manager:
If FlexFlash is enabled and the boot policy contains Local Disk, SAN Boot, or iSCSI Boot, then the boot order cannot be determined. You should disable FlexFlash before using any of these boot options, and enable it after bootup is complete.
Cisco UCS hardware information and inventory data about the controller and SD cards is not collected.
Monitoring of the controller and SD card status or health is not supported. In the case of a failure of a FlexFlash controller or SD card, no faults or errors will be displayed in Cisco UCS Manager.
Formatting of the SD cards is not supported.
Booting from SD cards using the Cisco UCS Manager Boot Policy is not supported.
After you update and activate the CIMC firmware, you must power cycle the server to update the FlexFlash controller firmware.
This procedure describes how to enable the FlexFlash SD card support in a local disk policy.
