Background

• Server: Dell PowerEdge R510 (New, no previous OS installations)
• RAID Setup: RAID 10 totaling 1.64 TB
• VMware: ESX 5.0 update 1

Issue

While attempting to add storage on VMware esxi 5.0 I received the following error:

An error occurred during host configuration. Call “HostDatastoreSystem.QueryVmfsDatastoreCreateOptions” for object “ha-datastoresystem” on ESXi “xxx.xxx.xxx.xx″ failed. An internal error occurred in the vsphere client.

Procedure to Correct Issue

• From the console run command to get correct name of disk:

fdisk -l

• From the console run:

partedUtil mklabel /dev/disks/<disk name> msdos

• Now attempt to once again Add the Storage.

Thanks to Edward Grigson at vexperienced.co.uk for pointing me in the right direction.
