When attempting to connect to the luns, what messages are you getting on the FAS console, if any? Do you see connects/disconnects?

Toasters,

I am having a heck of a time creating and connecting luns from a Windows 2003 Server. I have installed the latest and greatest Snapdrive and DSM on the system, and I'm running Single_image cfmode on a FAS3020C with ontap 7.2.2. Also, I am using dual Emulex LP10000 HBAs on my hosts.

When I attempt to create new luns in Snapdrive, the system creates the luns (i can see the IGroups and luns in filerview) but then it times out trying to reconnect to those luns. After this I can see the Luns in the HBAnywhere Emulex software but not in Snapdrive or DSM. Not only that, but I see each lun 4 times, which means the pathing/masking/igrouping is correct. I can also see all 8 drive paths as drives listed in device manager, but there is nothing in Disk Management.

Has anyone seen this or know what direction I should go in? I have a call with Netapp escalated to engineering, but I thought I would also reach out to some real experts here!

TIA,

Fred

Thanks everyone for the response on this. The problem was that in order to use Emulex HBAs with Snapdrive and DSM, you need to have a special Netapp-approved Emulex driver, which can be found here:

http://www.emulex.com/netapp/support/storport.jsp

After doing the basic install, you need to run the "autopilot installer" to get it to install HBAAnyware.

Netapp also recommends that you install Snapdrive version 4.2.1D2 to fix "timeout" -type bugs.
