Can not create any Aggregate because of sufficient disk

arinokitoku · ‎2016-01-04

Hey everyone,

I have running an Netapp Ontab 7.3.7P1

and i want to create an Aggregate, but when i do this the server tells me he has not enough disk:

"You do not have sufficient spare disks to create a 'RAID-DP' aggregate."

but i see that three disk are used for the root Aggregat and the other disk are "empty"

ST-01> sysconfig -r

thank you for your help

Those are on your partner node.. You need to log into partner and run aggr status -s

That current node has no spares which is bad

As in the other reply, you need to have spare disks on your controller to create an aggregate.

you need a minimum 3 drives to create a RAID-DP aggregate as you need one data and two partiy drives.

the drives showing as partner are owned by the other controller in what will be a HA system, you need to connect to that and see if you have spare drives there.

however in a small system like this, i would suggest you may not need more aggregates.

what are you trying to achieve?
