  12. Type info cX then press Enter, where X is the Ctl # (example: info c1)
     
  13. Examine the output to verify all drives are OK and in a non-degraded status, and check to see that Unit "u0" "Status" column shows INITIALIZING with a % complete (typically 0% or 1% for quite some time)

From Endura Utilities:

  1. Verify that the system starts up properly and is Online, Synced, and Registered.

From WS5200 Software

  1. Verify that video is recording and that there is playback.
     
  2. After the array initialization reaches 100%, the RAID-6 status will change back to "OK" (This can take 6-16 hours depending on the size of the array).
