MicrosoftMigration from Fall 2019 to Spring update 2020
I tried manually migrating session hosts to a new host pool last week and it was incomplete.
Although it could be used as Windows Virutal Desktop, the resources of the host pool were not sufficient.
ARM Parmeter:vmTemplate and so on ware blank.As a result, I could not add session hosts from Azure portal.
Is it possible to modify a host pool resource?
Thanks for fixing.But, unfortunately, it didn't fix properly.
The input form for adding a session host is now displayed and this has been fixed.
However, there seems to be an error in input validation.
Is this a problem for my environment?
Error message
The value of deployment parameter 'vmInitialNumber' is null. Please specify the value or use the parameter reference. See https://aka.ms/resource-manager-parameter-files for details.
- PavithraTCould you give me the following info:
Was the hsotpool completely empty when you started the Add VM workflow?
Were you asked to fill out the VM Prefix before seeing this error?
Do you have VMs in the resource group with or without the prefix?
I validated the fix prior to deploying it (had 3 different scenarios) and I was able to successfully create VMs. The scenarios were all around adding VM to an empty hostpool or a hostpool with a previously failed VM creation (due to domain error, etc.). This info will give me more info to repro the issue.
