This is a blog for John Weber. One of my joys in life is helping others get ahead in life. Content here will be focused on that from this date forward. John was a Skype for Business MVP (2015-2018) - before that, a Lync Server MVP (2010-2014). I used to write a variety of articles (https://tsoorad.blogspot.com) on technical issues with a smattering of other interests. I have a variety of certifications dating back to Novell CNE and working up through the Microsoft MCP stack to MCITP multiple times. FWIW, I am on my third career - ex-USMC, retired US Army. I have a fancy MBA. The opinions expressed on this blog are mine and mine alone.

dot net v4 breaks iSCSI from NetApp v6.3sp2

 

edit 15 May 2011

Some feedback from NetApp is that this will work *IF* the SDW and NET3.51 are installed first before putting NET 4 into place.

---

In our environment, .net v4 also appeared to block installation of BES 5.0.3.  My support chain contacted NetApp engineering, who says that .net v4 is supported.

FWIW, we are using Server 2008 R2 SP1, with all updates (straight install), VMware ESX and ESXi v4, UCS hardware.  I do not know the NetApp filer model/version.

What we saw:  after install of the base O/S, we installed the NetApp v6.3sp2 LUN driver.  Everything appeared to work failry well, until we committed to the LUN and the connection process started.  All we ever got was the 120 second time out.  On the back end, the LUN looked connected at the NetApp, but on the server, there was nothing.  Attempts to reconnect at that point resulted in being told that LUN was already dedicated.

Removing .net 4 components from the server allowed full, normal, LUN connection.

 

YMMV
