Dear all
These past weeks we have been experiencing intermittent power outages. After our UPS batteries drain our Hyper-V Cluster shuts down. However when power is restored our Hyper-V cluster takes a very long time to start up. In fact I wouldn't be able to ping it or browse the folders containing our VM VHD files. I am able to ping our Blade Server nodes. After about an hour and a half the cluster service comes back on and I am then able to manage it via Failover Cluster Manager. All our VMs then start up successfully.
Let me explain in brief our current setup. We have an IBM BladeCenter with 3 blade servers and cluster storage. One of our VMs is running as a Primary Domain Controller (PDC). However for redundancy purposes I have an additional domain controller running on a physical server and this is also hosting DNS.
What I cannot understand is why the cluster service takes so very long to initialise. When I do a netdom query fsmo I notice that all roles including that of PDC are residing on the VM Primary Domain Controller. Should I transfer all these roles to our second domain controller so as to resolve this issue?
Your comments and help would be much appreciated.
Thanks
Pierre
