I am trying to bring a Mac Mini 5,3 online with vSphere 6. The system originally came with two 500GB 7.2kRPM drives, and I swapped one with a brand new OCZ ARC100-25SAT3-480G SSD. I am booting from a SanDisk 64GB USB plugged into the back.
I brought the system online, added it to my vCenter, created a new datastore using the remaining 7200RPM drive, and all was well up to that point. As soon as I attempt to create a new datastore on the OCZ drive, the host becomes unresponsive to either vCenter or the old thick client. At the console I am still able to log in and look at the logs but that is about it, and it will even hang if I attempt a restart from the console so I have to manually power cycle it. If I leave it running, after a very long time (more than 10 minutes) the thick client will eventually throw the following useless error:
Call "HostDatastoreSystem.CreateVmfsDatastore" for object "ha-datastoresystem" on ESXi "octo" failed.
So I tried using partedUtil to remove partitions and do it again, with no change as soon as I tried to create the datastore (UI becomes unresponsive). Then I booted the machine using an external drive with OS X 10.10.3 on it and tried partitioning the drive MBR/FAT32, wrote and read a few files to make sure the drive actually seemed to work, and booted it back on on vSphere 6. When I attempted to create a Datastore again, I still got the same behavior.
After a reboot, this is what partedUtil reports for the disk:
