ESXi v6.5 and disk encryption: a perfect storm

The combination of an HP Server (in my case a DL180) using a HP RAID card (in my case a Smart Array p840), SSD drives in a RAID 5 level or higher, and turn on volume encryption at the RAID card, causes the VMware datastore to go disappear!  See what I mean by perfect storm?  That exact combination affects only SSD datastores, not SAS or SATA.  ESXi knows the partition is there, but can't do anything with it.  After spending time on with VMware technical support I learned that VMFS volumes have to volume descriptors, and the two got corrupt in this instance.

"Error: The primary GPT table on '/dev/disks/naa.600508b1001c6ea0a7586ed479f494c5' is OK, but secondary is corrupt. Fix secondary table? This will move secondary at the end in case it is not at the end already. It will also set LastUsableLBA to use all the space at the end. diskSize (3125428400) AlternateLBA (3125428399) LastUsableLBA (3125428366)
gpt"

Apparently this is a known issue, that fix to upgrade the RAID card driver from from nhpsa version 2.0.10-1OEM to version 14 or newer.  Version 10 is what is included on the HP customized ESXi6.5u1 ISO.

I lost a lot of time on this one.  As I built a bunch of VMs on the datastore only to loose them.  Then to narrow down this issue and work with VMware technical support.
