Solved: Re: 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 · ‎2020-08-03

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 ?
