Varonis and NTP QFS on NetApp
by Milazzo Giacomo 02 Feb '11

02 Feb '11

Hi all, for the moment I've few details for this issue has been reported me from a collegue of mine working in another site. For what I can tell you now software is running on a FAS 3170C with DoT 7.3 It seems that there's an issue running both Varonis and NTP QFS on this system. As probably you know both product, NTP and Varonis, use separated NetApp "file policies" (fpolicy) that can interact with the external engine of reporter or that can act as source of control. Now it seems that under certain circumstances these two different but concurrent NetApp file policies cannot simultaneously run and the one or the other or both crash. I would for now know if you are aware of issues on running on the same NetApp system both products or if there are some particular workaround that can be applied. Thank you in advance, Regards

latency measurement in DFM/Management Console/etc
by Fred Grieco 31 Jan '11

31 Jan '11

How does the Netapp or DFM measure volume and lun latency? Does it just measure how long it's taking to service requests from the back ports to the front ports? Or does it measure some sort of fibre ping to the host? I am looking in the management console in DFM/Ops Mgr and seeing spikes of very high volume and lun latency (seconds...) on an N-Series IBM gateway filer. I've looked at all the usual suspects, including misaligned VMs, high correlated IOPs, delays on the backend disk, deferred consistency points. Nothing is matching up. Most of the connected systems are on a Cisco UCS with NPIV. The systems with the lowest IOs have the highest latency numbers. Thoughts? TIA, Fred

write cache setting for Windows
by Fred Grieco 20 Jan '11

20 Jan '11

This seems like a newbie question, but I'm confused and found limited info on this. Should I be using the "Enable Write Caching" setting on my Windows disks that are Netapp lun (FC) based? Does this tell Netapp to use write caching for that lun/port, or does it tell Windows to cache somewhere on the local system? TIA, Fred

R: Snapmanager for Exchange - Nice issue...incredible :-)
by Milazzo Giacomo 14 Jan '11

14 Jan '11

As from my mail I've already run the TS Client in "console" mode (/admin from Windows 7, Vista or XP SP3) and I've already tried the "native" console in vCenter (or vClient...). Not tried VNC but I don't think that customers could be happy to have VNC installed ONLY for this! It's incredible to think that NetApp engineers did not think that this environment is nowadays quite normal!!! And this is a NEW bug because I've always run SME config wizard till version 6 when on W2K3 and Exchange 2K3/2K7...this is new for E2K10 on W2K8 64bit! I'm really disappointed but smiling... Regards, Note: I always run TS client in console mode!

That should work. Or, you could just go to vcenter. That's the console to. There is always dameware, or VNC.

Obviously the only way to access to the VM is using Terminal Services...I've tried of course both the vCenter console and the MSTSC client in /admin mode. No luck. Suggestions?

Moved volume to new filer, administrator ACLs now invalid?
by Steve Losen 11 Jan '11

11 Jan '11

Greetings, We replaced a filer named home2 with a new head. We physically moved disks from the old head to the new head. One of the volumes that we moved uses ntfs security style. I used to be able to map the volume/share as user home2\administrator and had "full contol" on everything. Now, however, the home2\administrator user on the new head has a new SID while the ACLs in the volume display the old SID. So now Administrator has limited access rights (can't drill down into folders, can't change ACLs, etc.) Doesn't the local Administrator user trump the ACLs ? Anyone have any suggestions? I'm a Unix guy with limited Windows knowledge. By the way, the filer is a member of a Windows AD domain, but I'm not a domain admin, so I don't have a privileged AD account. That's why I use the local Administrator account. Do I need to get a domain admin to help me? Steve Losen scl(a)virginia.edu phone: 434-924-0640 University of Virginia ITC Unix Support

Netapp Instructor Position Open
by Nick Bernstein 27 Dec '10

27 Dec '10

Hi all, I just wanted to let you know that there is an open position for a Netapp Instructor. You should have extensive real-world netapp experience, be personable, funny, able to tell stories and explain complex subjects in a simple manner. People who have worked as PSEs are probably a good fit. The salary is very competitive, but the main benefits are in the flexibility and schedule. You'll get to travel (I've been to places like hong kong on the company dime) and meet lots of people. I generally only work about two weeks / month, but some some instructors work every week. We will happily teach you how to teach, but just to be up-front, the process of becoming an instructor isn't instant. You'll have to take each of the course three times (one to audit, one to co-teach, and one supervised-solo), and you'll have to do this for the fundamentals class, the san, nfs, cifs, data protection and boot camp classes - it can take a while. Once you're through that however, I can personally attest to the fact that it's an *amazing* job. You would be reporting to me, and I'm a pretty darn good boss. :) Well, I am if you like my management style, anyway. Basically all I want is regular reports on how things are going, what help (if any) you need to do your job better, and then I leave you the heck alone. One of the main benefits of this job is you are your own boss, effectively sub-contracting, and we just make sure you've got everything you need, make sure your reviews are consistently good, and you're getting exposed to the new stuff coming down the pipe. There will also be great opportunities to get exposed to all sorts of other technologies too - cisco, vmware, ubuntu linux - it's really fun to be able to audit a whole range of different courses, and then bring that back to your netapp classes. If you're interested, please email me your resume, or a link to it - any standard format is fine. For bonus points, pretend you're talking to an eight year old, and explain why the sky is blue. Feel free to look it up, but the actual answer should be yours. Kindest Regards, Nick Bernstein, Director of Netapp training, ICM PS: If this is an inappropriate use of the list, please accept my apologies in advance - I've been on this list for a number of years and have always been impressed by the members; I wanted to give list-members first shot at the position.
