Lost access to volume … due to connectivity issues

This post was originally published on this site

Hello,

 

I have a brand new SYS-E200-8D Micro Server eqipped with 64 GB RAM and a 1 TB Samsung EVO 850 PRO SATA 6 SSD and installed ESXi 6.5 on it.

I have currently deployed one Windows Server 2016 RTM Virtual Machine on the SSD that acts as the Datastore.

 

But as soon as I do storage performance testing within the VM (I use CrystalDiskMark) I get the following warnings in the Monitor tab of the Datastore:

 

Successfully restored access to volume 58399b3f-53265d09-9851-0cc47aca3b52 (datastore1) following connectivity issues. Saturday, November 26, 2016, 20:47:22 +0100 Warning

CrystalDiskMark also reports very bad throughput for the C drive, which is physically stored through the vmdk file on the Datastore (which makes sense because of the above mentioned warnings).

 

Any ideas what could happen here and why I get these warnings?

I have also a Mac Mini setup (16 GB RAM, 256 GB Samsung SATA 6 SSD, ESXi 6.5 installation) where these warnings don’t occur when I do storage performance tests.

 

Thanks for your help & input,

Reconfigure Storage vRA API

This post was originally published on this site

Looking to add a disk via REST API. 

So we’re doing a GET on https://$host/catalog-service/api/consumer/resources/$resourceid/actions/$resourceActionId/requests/template

Then POST on https://$host/catalog-service/api/consumer/resources/$resourceid/actions/$resourceActionId/requests

Anyone know what the exact content we are using?  Do you have to take the entire template with current default values + inject your new storage variables (which should only be $size per the GUI mandatory fields) ?

Or

just submit your new storage variables into the Content of the request
