Windows Server Limitations
Consider the following limitations if any RN is running Windows Server:
(Windows Server 2012 R2 Only) It is possible that the mouse may not be activated when an RN is running in test mode or production mode and when launched from the RN’s VNC console. For more information and workarounds, go to RN Console Mouse Problems. This bug will be resolved pending a XenServer release of a new BIOS or Microsoft fix.
(Windows Server 2012 & R2) When a REFS volume in Windows Server 2012 or R2 is protected, the Recovery Node for the same will be in standard NTFS. This is also true of a Bare Metal Restore.
(Windows Server 2012 & R2) When a deduplicated volume in Windows Server 2012 R2 is protected, the Recovery Node for the same will again be a standard NTFS. This is also true of a Bare Metal Restore. Additional caution should be used in allocating RN disk space as the Quorum agent on the Protected Node will report actual disk usage, which might be far less than when data is stored in its normal form.
(All Windows Server platforms) When the onQ Event Log reports 3010 code for any Windows PNs, both 32-bit and 64-bit, the auto-upgrade fails. Perform one of the following workarounds in the order that they are listed:
(Agent‑based PNs) Restart onQ Service on the PN.
Reboot the PN.
Uninstall and reinstall the latest msi package at C:\Program Files\Quorum\installer.
