My first Azure Stack TP2 POC deployment ending in disaster…

Today I had the opportunity to have an attempt to deploy my first Azure Stack TP2 POC. Having this DataON CiB-9224 available allowed to have a go on deploying an Azure Stack TP2 POC environment. I was able to achieve this after finishing some testing with Windows Server 2016 with the platform. The results of those tests are available at https://mwesterink.wordpress.com/2017/01/19/case-study-running-windows-server-2016-on-a-dataon-cib/

Before I started testing I reviewed the hardware requirements which are available at https://docs.microsoft.com/nl-nl/azure/azure-stack/azure-stack-deploy

Unfortunately, a small part made me wonder if I would actually succeed in deploying Azure Stack. Here’s a quote of the worrying part:

Data disk drive configuration: All data drives must be of the same type (all SAS or all SATA) and capacity. If SAS disk drives are used, the disk drives must be attached via a single path (no MPIO, multi-path support is provided).

Damn, again a challenge with MPIO. Such a shame since I meet all other hardware requirements.

So decided to have a go and figure out why MPIO is not supported by deploying Azure Stack TP2 anyway. I followed the instructions at https://docs.microsoft.com/nl-nl/azure/azure-stack/azure-stack-run-powershell-script and see what happens…

I used a single node of the CiB-9224 and used 4 400 GB SSD disks only. I turned the other node off and I disabled all unused NICs.

After a while I decided to check its progress and I noticed that nothing was happening at a specific step (there was a hour between the latest log and the time I went to check). Here’s a screenshot where the deployment was ‘stuck’:

Seems like the script is trying to enable Storage Spaces Direct (S2D). Knowing that S2D is not supported with MPIO I terminated the deployment and wiped all data because I knew I was going to be unsuccessfull. At least I know why.

I didn’t meet all hardware requirements after all. Fortunately it gave me some insights in how to deploy Azure Stack so when I do have hardware that meets my requirements, then at least I know what to do…

Looking at the requirements again, it’s obvious that the recommended way to go is with single channel JBOD.
