MS KB2949927 with Unmounted VMFS volumes

Post by cstemaly » Oct 15, 2014 10:53 pm

I came across this thread on Technet: https://social.technet.microsoft.com/Fo ... proinstall

The fix for this seems to be to enable automount in diskpart. I recall explicitly disabling automount so that my connected iSCSI VMFS volumes would not be brought online within Windows (which as I understand it, ruins the volumes).

Sadly, I do not have a Veeam server with connected iSCSI volumes that I can test on, so I'm hoping someone out there either:
1. Has a test system ad can test it
2. Didn't know about this and installed it without incident on their Veeam server
3. Could persuade Veeam to test it and get back to us in the weekly Veeam Community digest :)

From what I know starting with v6.5 veeam updates Sanpolicy to offline shared and isn't using diskpart. http://www.veeam.com/kb1446

I checked my config to confirm, but if you want to be extra careful, you should wait for veeam's answer.

Vlad is correct, in order to keep production LUNs uninitialized, Veeam B&R server automatically sets SAN policy to offline mode and does not use automount command anymore, however I'm not sure whether SAN policy settings override automount configuration.
