Last night whilst attempting to configure our Hyper-V cluster I managed to hit the following problem when trying to add additional VM’s, which were contained on the same Disk LUN and Server
‘an error was encountered while loading the list of available virtual machines’
”Cannot find path xxx’
HotFix 951308 http://support.microsoft.com/kb/951308 now resolves this issue.
It turns out that you were only ever able to have one VM per Service or Application group which isn’t much good if you have multiple VM’s running on the same Disk LUN. this is now resolved under the following heading ‘Allow for more than one virtual machine in a “Services or Applications” group’
Think I’ve gain a couple more grey hairs over this one!!
Just need Microsoft to resolve the issue where by you cannnot add virtual machines to an already created serviceapplication group which has assign SAN storage. Instead you will need to use the wizard to detect the VM’s and then add your cluster resources to that group (File Share For Example)
Also addedresolved in this hotfix are the following;
- Changes to the virtual machine view
- Changes to virtual machine actions
- Add support for mount points or volumes without a drive letter
- Changes to the virtual machine refresh action
- Behavior changes if any node of the failover cluster has a disconnected virtual machine
- Behavior change when you add a pass-through disk to a virtual machine
- Behavior change when the parent differencing disk is not on shared storage
- Volume path copy
