If a hard drive fails in an array that is configured as a RAID 1, 5, 10, or 50 logical drive, you can recover the lost data by rebuilding the drive. Cluster mode allows the controller to operate as part of a cluster. Is there some error thrown in the event log that I can hook a warning event on to?
Now there are a few cases where it can end up being the riser card causing the issue, but replacing the raid kit seems to fix it more often than not.

Usually, you must format a disk if:. In Write-through caching, the controller sends a data transfer completion signal to the host when the disk subsystem has received all the data in a transaction. If the drive is not a boot device, the logical drive number is not critical. The default is 30 percent. The contents of the cache are flushed to maintain data integrity. It displays the array, and array number, such as A While pe28550 can get at the riser memory and the raid key without removing anything from the server, it will make your life a whole lot easier to take out or at least lift up the entire riser itself to get at the battery clip.
