Error Messages in Operations Manager

Hello team,

can someone give me some details about attached error-messages.

I do not really know what they wanna tell me. 😉

Enclosure Failure and Enclosure Failure Controller2: belong to one Shelf or are these several and independent ones?

Overcommitted: How can this be if there are only fullprovisioned Volumes and LUNs in this aggr. No Thin Provisioning enabled/used.
Does this refer to deduplication?

Thanks for your support.

Kind Regards, Michael

Not sure about your shelf failures, but aggregate overcommit warnings can also be triggered by volume autosizing (auto-grow)...

Thanks for the hint.

This will match with the configuration of my customer.

Good to know! 🙂

mkerst,

The first two means some component of a disk shelf (i.e. enclosure, fan, power supply) has failed on your controller. In a nutshell, call Technical Support as soon as possible to get this issue resolved.

The last event has to do with thin provisioning. It means you've given-out or "committed" more space than you physically have available in the aggregate. You've committed 22.6 TB out of a 12.9 TB aggregate, so you're over-committed. This isn't necessarily a bad thing, but you need to decide how comfortable you are with thin provisioning and at what level of over-commitment you want to stop at.
