I have an LS220DE (firmware 1.63-0.04) that is running 2 Seagate ST3000DM001 3TB drives in raid 1. During some other system maintenance today, I accidentally pulled power from the array without shutting it down properly. Now it shows the array as running in degraded mode, but there are no other indications that anything is wrong. The disks show as normal, and check disk is grayed out when a single disk is selected. I can access the files as normal and everything looks fine, except for the amber error code I12.
How can I repair this issue?
