MCS Deployment with Azure emphemeral disk

[Sean Bernard1709160607]

Hi everyone,

 

since may 2021 VAD Service is supporting Azure emphemeral disk via PowerShell.

(https://docs.citrix.com/en-us/citrix-virtual-apps-desktops-service/install-configure/resource-location/azure-resource-manager.html#azure-ephemeral-disks)

 

Is anyone using it already?

I've tried many times but every time I've become an error in WebStudio.

An error occurred. Contact Citrix Technical Support, and provide the transaction ID above.

I have tried with an Windows Server 2019 Datacenter (smalldisk) Image with an disk size of 32 GB and also ans normal Windows Server 2019 Datacenter Image with an disk size of 128 GB.

The VDAs should have an size of D4ds_v4 and D16ds_v4. This two sizes have enough temporary disk space to use emphemeral disk.

 

 

 

Has anyone an idea or solution?

your catalog name is too long -  it's a known issue, I hit the same thing -  shorten the catalog name to something small :)

 

Fix will be out soon
