Ian, Can you confirm that you are speaking to ONTAP 9.8? I know engineering has made many improvements in EMS alerts on the Events card on the dashboard in 9.9.1RC which is now available. Errors •Emergency EMS Events within the last 24 hours •Node down (not healthy) •Broken disk •Shelf has error •Network port down •License entitlement non-compliant Warnings •Health Monitor Alerts (in the past 24hrs) •Unassigned disks •LIFs not at home port •Volume Move information (for the past 24hrs) •Failed Vol moves •Vol move – admin intervention required Let me know the version and I can confirm for you if this is the expected behavior and raise a BURT. Thanks, Chris

Tim, In ONTAP 9.9.1 you can use "more options" and remove the _dest from the UI. In 9.8 it required either a prefix or a suffix. Hope that helps! Chris

Tim, Engineering is making progress... While I would love to post our plans publicly, that's not something we can do. My recommendation is for anyone who wants to know what these plans are, to reach out to your NetApp account team and or partner and schedule an NDA briefing on System Manager. Another way engineering is working to get some of these features out faster is to backport changes into P releases. A couple of the items that Glenn mentioned in his posts planned to be in P releases of 9.8. Thanks, Chris Gebhardt

Chris, The items you mention are all fixed in ONTAP 9.9.1 which was released on 5/6/2021. There are many more that are detailed in the customer product communiqué for (RC1) of NetApp® ONTAP® System Manager 9.9.1 management software. The one I haven't shown in the graphics below is the performance improvements. Engineering has been making progress in the underlying API and UI responsiveness. 9.9.1 has got better and more performance improvements are coming in future releases. Volumes List Columns with %Used and more. List view for tiers (aggregates) Used and reserved is now a prominent value. Hope this helps! PM me if you would like to discuss further or have any other questions. Thanks, Chris Gebhardt Principal Technical Marketing Engineer - Manageability

You can not do this through the RCU Wizzard however if you want to deterministaclly give your clients the same IP Addresses each time, you can use something like DHCP reservations. You would have to provision the desktops, obtain the MAC addresses then populate DHCP with the MAC / IP reservation.

Do you have a case with the GSC on this issue? They may be able to try to replicate it and make sure we are collecting the right information... I tried to replicate this and couldn't create the error nor could I find what vmount2.exe was doing during NetApp cloning vs VMware Cloning. Can you look and see if the VMware Mount Service for Virtual Center is running on the vCenter Server? If so is it set to manual or automatic? Can you stop the service and try the clone again. The vmountvpx service is the vmount2.exe application. It doesnt seem that this should need to be running. There may be other apps like VCB or converter that may require it but not VSC. I would try that first and then work with the GSC and VMware support to run some more tests and figure out what is happening in your environment. Thanks, Chris

There is a VMware KB that provides info on how to verify that the cust spec is running... It may be useful to get the %SYSTEMROOT%\Temp\guestcust.log file and see what that says if anything. http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1006842

I would say that either would work just fine however lets consider the standardization of alignment for the cloud. Some vendors recommend different sizes based on their own filesystem and what is best for them. It is the opinion of many that making the starting offset 1mb as that is compatible with all storage vendors and allows for maximum portability should a migration be required from one vendor to another. MS has elected to use the 1mb offset for Window 2k8 and Windows 7 and this is a move in the right direction. Please have a look at Vaughn Stewarts blogs which he details alignement and provides links to others documentation. http://blogs.netapp.com/virtualstorageguy/2009/06/io-efficiency-and-alignment-the-cloud-demands-standards.html http://blogs.netapp.com/virtualstorageguy/2010/04/raising-awareness-around-the-misalignment-of-data.html Thanks, Chris Gebhardt

Cross post from the NetApp Virtualization Effect Blog: http://blogs.netapp.com/virtualization Subscribe to the NetApp Virtualization Effect Blog for all the latest & greatest of NetApp & Virtualization Technologies. Posted by Chris Gebhardt - Reference Architect There has been much talk in the blogosphere lately about NetApp technologies. In particular NetApp’s space efficiency and performance capabilities. Well I figured that it was time to post some information that may help answer a couple questions that people may have. We have been conducting research in our labs on how customers can use NetApp space efficiency technologies while providing exceptional performance. Well the problem may sound complex but the solution is actually simple. It's in there!!! The secret sauce is in Data ONTAP & Intelligent Caching! Here are just some of the results that we have captured. The setup We used one NetApp FAS3170 head w/ 23 data disks and a 16GB PAM card and booted 1000 XP virtual machines. We used 8 - 16 CPU servers with 128 GB of memory each running VMware ESX 3.5. We provisioned this infrastructure using NetApp RCU and created 6 - 40GB NFS datastores each with approximately 167 VMs’ each. That’s right, we had 167 VMs’ of 10GB each in a 40GB datastore (with room to spare). Since RCU was used to provision these VMs they were already deduplicated! We then booted the virtual machines all at the same time with Intelligent caching disabled. We then used performance advisor to graph the disk throughput, network throughput and NFS protocol latency to see what effects dedupe has on this massive read storm. Here comes the good stuff, we then waited a bit to get half way through the boot storm and then enabled Intelligent Caching with PAM. Here is a screenshot of the entire boot of 1000 virtual machines. As you can see it takes about 12 minutes to boot these 1000 virtual machines. This screenshot is is of the NFS protocol latency and as you will notice the average latency is ~75ms without intelligent caching and ~7ms with intelligent caching (Thanks @Tintop). At about 15:39 I turn on Intelligent caching and latency drops by 10X! This next graph shows the exact same time period but for Disk Throughput. By using NetApp Intelligent Caching in combination with disk deduplication you can reduce the IO coming from disk because not only is the data deduplicated on disk but it is also deduplicated in CACHE! And just as another data point here is what the network looks like when running this boot test as well... Using NetApp deduplication can not only reduce the storage footprint but allow customers to serve data more efficiently with NetApp Dedupe Aware Intelligent Cache. This allows customers to reduce the number of spindles needed to everyday workloads and handle peak workloads such as boot storms while delivering a robust end user experience. http://blogs.netapp.com/virtualstorageguy/2009/09/run-everything-virtualized-and-deduplicated-aka-chuck-anti-fud.html#moreIf you would like to read more on NetApp Deduplication and Performance please take a look at Vaughn's blog over at The Virtual Storage Guy Follow me on Twitter@chrisgeb

Jesse, Could you send the logs to me at chrisgeb@netapp.com? We will need all logs found in the <installation directory>\logs folder. The default installation directory is C:\Program Files\NetApp\Rapid Cloning Utility. Navigate to the installation directory, right click on the logs directory, and choose "Send To" -> "Compressed (zipped) Folder" and send me the resulting file. As a side note RCU 2.1 was just released yesterday and can be downloaded for free from the now.netapp.com website! Thanks, Chris Gebhardt VDI Reference Architect Server Virtualization NetApp Follow me on Twitter: chrisgeb

Corfdir, Thanks for the question. I would try to upgrade to RCU 2.1 (it was released yesterday) as it may fix the issue you are experiencing. Unfortunately support for RCU with vSphere will be not be available until the next release of RCU. Anecdotally I have heard that 2.1 may work for NFS with vSphere... I can't guarantee anything as we don't officially support it but for your test environment it may give you what you need.

Eran, Thats a good suggestion that we can take a look at doing something like this within the business unit. Are you specifically talking about what integration we have with each connection broker providers? Citrix can import VMs into XenDesktop that were created with RCU via a CSV file. Quest vWorkspace can create the VMs by calling our ZAPI's Leostream can automatically discover new VMs that are within vCenter that were created by RCU Please give me some more details that you are looking for and we can try to provide some more info! Thanks, Chris

RCU 1.0 can be used for VMFS datastores however the cloning of the gold vmdk has to be done with RFWM and the mouting by hand. But otherwise RCU can be used to clone the VM and apply the guest customization. Hope this helps... Chris
