Simulate failed disk with ADP AFF C190

Hello, 

 

I'd like to know what's happening when simulating a failed disk in ADP configuration on an AFF C190 with the following sysconfig -r :

If you have any idea ?

Yep!   P3 is the root part of the drive  P1 - Data 1  P2 Data 2   

 

That's normal,  The no spare default is for the data partitions.

Are you wondering because there's no (default) data spare with the C190? 

yb_benjamin

Yes exactly ! However, as you can see, the aggregate has been created by default and we've got a spare partition on each controller without modifying the spare policy.

Any idea ? Or maybe it's just for the root partition ?
