VDA error : Unable to initialize component

At the end of the installation of VDA 5.6 or 7.0 initialization of VDA component is done. During this steps it try to configure firewall port and setup DDC communications. During this process it fails sometime with error "Unable to initialize component"

As per CTX133350  this can happen when " Virtual Machine was cloned from XenDesktop Pooled static catalog and difference disk is attached to it. Note: This configuration is not supported and Windows OS should be re-installed after removing the difference disk." But this was not the case for me, it was because of firewall communication. I tried different windows firewall setting finally I have to let all the profile configured with everything "ON" option in order to make this work. Everytime you change firewall option you must reboot and then restart the process

How to remove arrogant VM from VMM

I had a trouble with VMM server itself when it was not allowing to update VM status . I tried using Hyper-V server console as well fail over cluster console . But nothing use to change the status of VM. I rebooted Hyper-V server itself but that also did not change the status of VM host name. Finally I saw blog which explain steps to remove VM from VMM console forcefully. I was not sure if that will delete the VM from storage as well.

Status of VMM vm was like this

I made copy of the VM on the storage to be on safer side. Then  I ran following command . First command to ensure that I am able to connect to VMM server via PS. Next two command is to remove VMM arrogant VM from VMM console.

After running above command status of VM were changed and I was able to choose all the status

 

The Citrix Credential Wallet service is not running

While doing storefront deployment we came across the error " The Citrix Credential Wallet service is not running"

It also had following error in the event log which point to some kind of timeout while starting the service.

We tried putting service into delay start mode to see if that fix the issue

While doing research we found that config file need to be modified if StoreFront server do not have Internet connectivity

 

And change the value from true to false and finally service got started

Allocating Lun to Hyper-V host

There might be multiple ways to allocate lun to Hyper-V clusters but I follow below way . Once lun is allocated via storage system it will be available via disk management on one of the cluster node. Bring it online and format it without drive letter and partition name.

Once drive is formatted open cluster manager and browse to storage right click to add the storage

Once added it will show up as available storage

Now we need to allocate this to cluster shared volumes

Once this is allocated it will showup under cluster manager and under SCVMM
