VMware vSphere 5.5 – Call “HostStorageSystem.ComputeDiskPartitionInfo” for object “storageSystem” on ESXi failed

Intel NUC

I recently installed VMware vSphere 5.5 on my Intel (Haswell) NUC (D34010WYH1).

Today I got the following error when I tried to create a VMFS 5 datastore on the SATA hard drive that I installed in my NUC:

Call "HostStorageSystem.ComputeDiskPartitionInfo" for object "storageSystem" on ESXi failed

A quick search of the internet took me to this solution which required logging as root and manually deleting partitions on the drive.

Fortunately I found a simpler solution.

I was able to create a datastore using the (legacy) VMFS 3 filesystem and then just upgraded it to VMFS 5.


Installing VMware vSphere ESXi 5.5 on an Intel (Haswell) NUC (D34010WYH1)

My vSphere hardware has long been due an update and I have finally got my hands on an Intel NUC ! Here is my (completely un-supported) parts list:

The D34010WYH1 NUC gives me the option of storing virtual machines on a 2.5 inch HDD or SSD inside the NUC (and the 1TB WD Red drive gives me a good amount of local storage to play around with). The RAM is low voltage (1.35v) which is required. The 32 Gb USB 3 flash drive is over-kill (only 4GB is required for vSphere 5.5) but it is very small (and pretty fast too). I needed the HDMI adapter to connect the NUC to my HDTV during vSphere installation.

The installation process is quite straight-forward and you will need the following:

Before installing vSphere we need to create a custom .iso image that includes the two .vib drivers that we downloaded. This is done using ESXi Customizer.

ESXi-Customizer 01

The first time you run ESXi Customizer select the vSphere 5.5 ,iso image and the network driver (net-e1000e-2.3.2.x86_64.vib) to create a customized image.

Run ESXi Customizer again and this time select the customized .iso image and add the sata driver (sata-xahci-1.10-1.x86_64.vib) to create a final customized .iso image.

I chose to burn my customized .iso to CD and install using a USB DVD drive – if you want to use a flash drive to install you will need to use UNetbootin.


In UNetbootin select the Diskimage radio button and then browse to the location of your final custom .iso. Select the flash drive to copy files to and then click the OK button.

In the BIOS of my NUC I disabled the UEFI option in the Boot menu. After that I booted from my USB DVD drive and installed vSphere to a USB 3 flash drive.

[I did test installing from one flash drive to another too and this also worked without any issues].
