I was able to get more information on this and looks like the lines of communication between Symantec and NetApp are open and the product managers are taking a look at this. Short answer is - yes there is a performance issue that Symantec noted which is why they disabled it.  Rough estimate was about 1/10 the expected throughput. Other then that I don't have much more info and hope that our PM's will be able to work with the Symantec team to improve this. ... View more

Can you try starting the iscsi service then restarting SDU daemon? There were a few burts showing dependency of the iscsi service to be on for NFS environments. Is it only the snap disconnect that gives you an error? ... View more

I've been speaking with our dev team and its not really clear if the  "redirected" mode is a MS requirement.  Do you have any documentation  from MS support suggesting this requirement? I've tried looking around online and haven't been able to find  any official documents on CSV resizing.  I've confirmed with our DEV  & QA that CSV resizing has been tested and confirmed (Both Shrink  & Grow). I'm sorry to hear about your support situation.  Let me see what I can do here. Can you collect the OntapWINDC logs and send them to me?   You've got a PM. ... View more

I'd like to take this up with our engineering team to see if the "redirected" mode is a requirement for CSV resizing.  Do you have a NetApp support case open on this issue?  If not, can you please open a support ticket and collect the OntapWINDC logs? Once the ticket is open, I can forward the information to our dev team. ... View more

I can confirm that CSV LUN resize is supported in SDW 6.2.  Also keep in mind that best case scenario would be to stop all I/O as mentioned in the IAG guidelines for resizing. • While a LUN is being resized, it might not be available for use, so plan your disk resizing at a time when applications are less likely to be accessing the disk. The limitation of shrinking a LUN is a known microsoft issue and can only be shrunk to half of the original size of the LUN. http://support.microsoft.com/?kbid=2020591 ... View more

There could be connectivity issues, cluster resource problems, and many other reasons that could be  causing this problem. Are you getting any errors when you do the failover?    Disconnecting the LUN should not cause any data loss but you'll need to use caution if there is an application or users writing to the LUN. I strongly suggest opening a ticket with support so they can have a look at the  environment to see if there are any problems. ... View more

Hi Scott, I looked around for any burts on this and wasn't able to find anything specific to this problem.   I did come across a KB article on Symantec's page that notes the same thing you had mentioned but doesn't have much details.  http://seer.entsupport.symantec.com/docs/323320.htm I've engaged some of the NetApp EV experts and should have a response shortly. ...

I would definitely plan for an outage if changing the volume language as recommended in the OnTap storage management guide .  Technically the first time cifs accesses a directory, that directory will be  converted to unicode. So during path lookups, all directories in the  path get converted.  Its the NFS side of the house that we're primarily concerned with and there may be some directories that have not been converted.   I would recommend schedule a maintenance window and follow the guide. ...

Is this a cluster?  I have seen some instances where there were issues with service dependencies and may want to check the snapdrive service. If the problem persists, I'd recommend using the  Data  Collection Tool for SnapDrive for Windows (ONTAPWinDC.exe)  and open a support case for further troubleshooting. ... View more
