This morning i had to power on our hardware due to a controlled power outage of all power on the campus.  The equipment was powered down last week.

When the 4100 came back up, it is showing 3 drives as failed.

RAID status shows as "degraded"

I have three volumes carved out as datastores and attached to 2 ESXi 6.0 Servers via iSCSI.

From vCenter, I can still see the datastores  and access the VMs that reside on the three volumes.

With 3 failed drives in RAID 6, how is this possible?
