We currently have a VessRaid 1840i. It was running perfectly, and then we had to power it down for an extended power outage. No big deal. When we powered it back on, the logical drive (LD0) was listed as offline. All the physical drives report as OK and and there are no other problems showing.

How do we get LD0 back online without having to lose all the data that is stored on it? Also, what could of caused this, as we would like to avoid this if the same situation comes up again.
