Adding a drive to a degraded Adaptec raid array

We have an Adaptec embedded SATA HostRAID controller and we have 2 drives that are mirrored.  One drive went bad, so I installed a new drive, but I couldn't find a way to add it to the array.  Finally I created a simple volume on the drive (within Adaptec's utility) and then it added the drive to the logical devices.  Under the logical devices, there is array1, which is still degraded.  How do I get this drive into the mirrored array?

In that link, the person reset his bios, which disabled his raid controller and he had to re-enable it.  I still have raid enabled.  I have the Adaptec Storage Manager utility installed on the server, but do not see a way to rebuild the array.

I went through similar problem, turned out root cause was buggy firmware and once I upgraded it then everything was OK.   You don't want to take chance that your degraded array will get lost, or rebuild gets done so that source and target disk was swapped.   You unfortunately didn't just stop when it didn't work as expected, and possibly (not probably) messed things up.

This is a situation where I strongly recommend going to the adaptec support site and getting advice from Adaptec.  You may have a problem with metadata.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

You have to do this in RAID BIOS for Adaptec I believe you hit CTRL-A during the boot sequence.  YOu may have to remove the array completely then create a new array with the new drive.  Of course make sure you have a backup of your data.

The only way I could seem to add the drive to the array was to first add it as a hot spare and then run a rebuild.
