Simply because they could use a custom Resource Pool and use that as the source. But my guess is that NetApp lacks the resources/budget/interest in order to serve their customer base properly, to make this happen. Hence the b%$sh^#t response you got.<br /><br />Cheers,<br />MarnixMarnix Wolfhttps://www.blogger.com/profile/09487479325587450184noreply@blogger.comtag:blogger.com,1999:blog-4414432572587218573.post-32267684978995695312016-01-11T10:35:35.877+01:002016-01-11T10:35:35.877+01:00Well, the very usefull comment from NetApp..

Guess it's better to contact NetApp support. Hopefully they're capable to tell you the deeper workings of this MP. <br /><br />Cheers,<br />MarnixMarnix Wolfhttps://www.blogger.com/profile/09487479325587450184noreply@blogger.comtag:blogger.com,1999:blog-4414432572587218573.post-26420794798813171102015-12-18T14:19:57.877+01:002015-12-18T14:19:57.877+01:00So... i don't understand how monitoring actual...So... i don't understand how monitoring actually works. We have 2 dedicated Management Servers for DATA ONTAP, so we enabled the Discovery Rule for those two (although the manual states that you should enable this rule for one Management Server only). Anyhow, when adding the controllers, you can select any Management Server you like, even while it is not running the DATA ONTAP software. Afterwards, there is no way of seeing which Management Server is doing the actual work, also there is no way of 'moving' controllers between Management Servers (since there is no Resource Pool). I can see the OnCommand event log being created and it is indeed working, but how can i determine if it is using just one or more Management Servers and if those are the correct (dedicated) ones?<br />Thanks!TommyGunhttps://www.blogger.com/profile/10429932130817713755noreply@blogger.comtag:blogger.com,1999:blog-4414432572587218573.post-61973670947719902822014-10-17T16:13:15.663+02:002014-10-17T16:13:15.663+02:00Just a word of caution about this MP/Plug-In, we’v...Just a word of caution about this MP/Plug-In, we’ve found that some of the rules that run/sync each day, actually Close all open alerts, ie. Data ONTAP: Volume Space Utilization (%) monitoring, then after a few minutes all of the closed alerts will re-open. This can cause 2 alert storms: 1. for Closed alerts 2. for New alerts. NetApp tech support states that because the re-sync rule, the one that syncs up with the NetApp controllers every so often (ie. every night), basically clears all such open alerts and then reopens them when it discovers threshold breaches. According to NetApp tech support, this is by design. I believe it is a flaw, but there is no word on whether or not they will fix or enhance this so that open alerts stay open and the repeat count gets incremented.Anonymoushttps://www.blogger.com/profile/06257530527845210191noreply@blogger.comtag:blogger.com,1999:blog-4414432572587218573.post-81805551546299334782014-01-17T15:14:18.531+01:002014-01-17T15:14:18.531+01:00Hello.

First of all thanks for this post as it is a great overview for configuring the MP.<br /><br />I recently installed the 4.0 version and I'm slightly confused on the wording of the documentation.<br /><br />I installed the MP, added my controllers, setup credentials, and completed the "Run Discovery Task" that is located inside the SCOM console. I also setup the SNMP alert destinations on the NetApp. The documentation mentions the discovery will occur by default in 4 hour intervals. So do I still need to enable the Rules for discovery?SCOM Artisthttps://www.blogger.com/profile/00374061314619380405noreply@blogger.com
