VCF 4.0 – HostPreparationException: No eligible cache disks found on ESXi

This post was originally published on this site

Hello,

 

I’m attempting to perform a bringup on 4x servers each equipped with:

– 1x 32gb flash (used to boot esxi)

– 2x 900gb SSD

 

Issue I’m getting is:

“Host preparation failed with the following errors: com.vmware.evo.sddc.common.hostservices.error.HostPreparationException: No eligible cache disks found on ESXi host”

 

From a google search it seems the VCF bringup requires two SSD with different size in order to use the smalled for cache and the other for capacity… is that true ?

If so… how can I make one disk appearing smaller ? (if ever possible)

 

Thx,

A.
