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

Hi all, for disk shelves DS4243 the configuration guide reports only a rule for disks "same type" in the same shelf, and not "same size". Is it possible to have, i.e., 12 1 TB SATA disks and 12 2 TB SATA disks on the same DS4243? Or, i.e, 300 and 600 SAS? In this way I could have, using software ownership in cluster, controllers with different amount of spaces... Regards

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.

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.

Virtual storage console RCU mistery...
by Milazzo Giacomo 23 Dec '10

23 Dec '10

Hi all, for the first time I've experimented the RCU tool that now is inside the VSC 2.0.1 for VMware. But during the tests I've noted something that left me doubtful. I've always thought (and this is the NetApp message to folk :)) that the "rapid" clone utility used some way the flex_clone or the lun_clone techniques to quickly create vmdk images starting from something on active file system volumes... I mean: vmdk on a lun/volume -> Data Ontap snapshot of this -> flex_clone -> rewritable image of the originating data and, of course, all this for dozens of VM performed very quick because there's nothing to transfer!!! Instead when I ran those test I've choosen a running VM, selected the NetApp menu item -> provisioning and cloning -> rapid clone and, looking both at the putty on my filer and on the status bar of vCenter I've seen no activities on the NetApp at all (no snapshots, no clone and so on...) while the vCenter reported: creating snapshot (a VMware one!!!) -> copying ....copying??? In short the same time and technique I could script or manually execute. So, why the rapid clone tool asked me for a flex_clone license??? And why if I would use it on FC or iSCSI LUN? I could understand for VMware datastore on NFS...And, last, why a flex_clone if there's NO cloning (data ontap) at all? Have I missed something? Regards,

Snapmanager for everything monitoring
by steve klise 22 Dec '10

22 Dec '10

I have about 10 SQL server running SMSQL and a couple Exchange Clusters running SME. We ran into a bit of an issue where some servers were not running the automated or scheduled tasks, and it went unnoticed for a day or two. The completion or failure job is set via SM email even if successful, so I get a few emails a day to say the least. What I am looking for is what folks use out there to monitor their SMGR jobs/backups. • Do you just rely on email, and if a job does not come in at its specific time, become alarmed? • Do you run a sys logger against the filers and look for those jobs/alerts? • Do you run some fancy script I can bribe you for, and I will buy you a beer in return? • Looks like powershell for Netapp is cool. I ran a snapshot script that was pretty cool.. Maybe ask for some help there. What do you use ? happy holidays! -- View this message in context: http://old.nabble.com/Snapmanager-for-everything-monitoring-tp30502273p3050… Sent from the Network Appliance - Toasters mailing list archive at Nabble.com.
