Installing VMware ESXi fails on Cisco UCS Blades with FlexFlash SD cards

When implementing a new Cisco UCS environment I encountered the following error when trying to install VMware ESXi 6.5 on a Cisco UCS Blade server with a FlexFlash SD card:

Operation failed

This program has encountered an error:

partedUtil failed with message: “Error: Can’t have a a partition outside the disk!
Unable to read partition table for device /vmfs/devices/disks……………….

The solutions is simple, perform a format of the SD card in UCSM before installing VMware ESXi. The format option can be found under:

  • Equipment -> Servers -> Select the server -> Inventory -> Storage – Controller -> Select the FlexFlash controller -> Format SD Cards
