We have been doing some testing with our 4 node Windows 2008 R2 Hyper-V cluster and SnapManager for Hyper-V.
We have some test Windows 2003 and Windows 2008 guests some with and some with out pass though LUNS.
Last week we had finally applied all the relivant hot fixes as per NetApp Hyper-V best practice and NetApp Technical support, and were able to get 100% sucessful jobs SMHV jobs of both types of guests with and without pass through LUNs.
To continue testing our IT manager did a live migration to move the guests around on the cluster, as you would if you were going to take some hosts off line for maintanence.
Our SMHV jobs started failing with the following VSS errors
Backup failed with VSS Retryable error.
(9)] Writer Microsoft Hyper-V VSS Writer involved in backup or restore encountered a retryable error. Writer returned failure code 0x800423f3. Writer state is 5.
For more information, look at the Hyper-V-VMMS event log in the Windows Event Viewer under "Applications and Services Logs->Microsoft->Windows".
Any ideas on what we have missed ?
We were expecteing that SMHV would not be affected by live migrations ??????
