Information

Background :

Customers using XenDesktop Machine Creation Service (MCS) with VMWare hypervisor may want to rename vCenter objects such as Datacenter, Cluster for various reasons breaks root path which results in an error "The cluster for resources could not be found" .This article tells why Citrix does not support the renaming vCenter objects.

Reason  :

During the MCS catalog creation  :
MCS creates a Provisioning scheme which is associated to the root path, the vCenter objects which are defined under the hosting unit in the hosting tab on Studio console has those catalog mapped, also all these information gets stored in the database during the creation of the catalog.
So if we go ahead and rename the vCenter objects from vCenter end, first of all DDC tries to connect to VMs through root path as our DB has this information stored in respective tables.
Even if we create a new host connection, we will not be able to map the existing Provisioning scheme with the new Hypervisor Connection due to limitation of Xendesktop Powershell SDKs.

Can retrieve the root path & vCenter objects information using powershell using the following commands :
PS C:\Users\administrator.WHOAMI>asnp Citrix*
PS C:\Users\administrator.WHOAMI> cd xdhyp:
PS C:\Users\administrator.WHOAMI> cd .\HostingUnits



Note : Modifying the DB tables using DB queries to modify root path is not supported.
 
Work Around currently available:

Create new hosting connection in Citrix studio which will in-turn have root path created pointing to new vCenter objects. 

1. If it is a case of MCS Random catalog, we strictly recommend to create a new catalog with the available master image using newly created hosting connection.
2. If it is a MCS Dedicated catalog , we can remove the machines (via Studio)from the XD database and leave them in hypervisor and account on active directory, we can read them as an Existing machines under Existing catalog.
