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

Error 12700 VMM cannot complete host operation while creating Virtual Networks

While creating virtual networking on one of the Hyper-V 2008R2 host

It was giving an error  12700 VMM cannot complete the host operation on <servername> server because of the error

I tried rebooting/removing and reading back to cluster . But then it always throw an error while creating Virtual Network. Because of this I was not even able to create VM on the cluster . It was giving error "Error 20400  1 parallel subtasks failed during execution.

Found MS KB 2486812 which explain how to fix and what is the root cause. Downloaded nvspbind and run it on problematic Hyper-V cluster.

 

And finally I was able to create Virtual Network
