ESXi Issues

Whenever you attempt to create a datastore, you are shown the following error:

Call "HostDatastoreSystem.QueryVmfsDatastoreCreateOptions" for object "ha-datastoresystem" on ESXi "172.20.1.26" failed.

To fix this issue:

1. SSH to the ESXi Server
2. run fdisk /dev/disks/<device in question>
3. delete any partitions that might exist using 'd'
4. create a new parptition using 'o'
5. Re-attempt to create the datastore in vSphere

Here is what I did with fdisk:

~ # fdisk /dev/disks/t10.ATA_____ST3500630NS_________________________________________5QG0D3KF

***
*** The fdisk command is deprecated: fdisk does not handle GPT partitions.  Please use partedUtil
***

Found valid GPT with protective MBR; using GPT

Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that the previous content
won't be recoverable.


The number of cylinders for this disk is set to 60801.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)
