MSA2052 not recognizing disk groups after power cycle

Hello,

 

I have a MSA2052 with 2 additional enclousures = 3

It is configured with several disk groups (RAID10) splitted over all 3 enclousures.

When I power off enclousure 2 to simulate a failure, all disk groups become degraded but everything keeps working as expected.

When I now power up enclousure 2 again, the head unit discovers it and states that all disks in this enclousure 2 were previously member of a disk group. See screenshot here: https://imgur.com/a/Ce9o3KV

I was assuming that the MSA detects that these disks belong to the existing disk group and becomes healthy again. But nothing happens ...

Is this assumption wrong? How could I bring back the disk groups to a healthy state?

 

Thanks
