OCPM performance alerts during aggr scrubs

colin_graham — Wed, 04 Jun 2025 15:12:18 GMT

We have a farily new installation of CDOT 9.1, OCPM/OCUM 7.1RC1

Every night, the lower powered 255x controllers trigger performance alerts during their aggr scrub - is there any way to filter this out?

an email is sent and when drilling down to the alert in the console, OCUM knows the scrub is running.

Thanks

Hello,

There was an earlier thread on this a little while back:

http://community.netapp.com/t5/OnCommand-Storage-Management-Software-Discussions/Aggregate-disks-over-utilized-LEGIT/m-p/129438#M23331

Anyway, it is an annoyance but once you put any kind of "real" workload on the system it will go away. The opportunistic nature of the scrub just takes over the aggregate from 0030-0530hrs for no apparent reason when the system is otherwise idle. Put real user workloads on there and the scrub drops back down to background noise. We actually "reintroduced" this behavior on another system that was in service for 3 years and we decommissioned all the workloads on it. Sure enough, OCPM started alerting us that the aggregate was over-utilized every evening (and even longer on Sundays).

Hope that helps,

Chris
