"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)
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.
