Windows Server 2008 R2 SP1 & Veeam B&R automount problem

By admin, February 26, 2011 21:35

I’ve encountered a problem when installing Windows Server 2008 R2 SP1 today and found the reason and solution pretty easy. It was due to Veeam B&R v5.0 automatically Disabled automount for SAN mode and W2K8 R2 SP1 requires automount to be enabled.


1. Disconnect all active iSCSI connections and REMOVE the Target Portal from iSCSI favourite tab. 

2. From command prompt, issue the followings:
> diskpart
> automount enable

3. Reboot the server then go ahead and upgrade your W2K8 R2 with SP1, it will take about 50 minutes to complete, yes, it did take that long even on latest powerful server.

4. Then issue the following AFTER reboot:
> diskpart
> automount disable

5. Reboot the last time and then re-establish all previous iSCSI connections as usual.
