We’ve been having an issue with our NAS Storage Server running a RAID 5 array. Basically not too long ago we had a bad powersurge and one of the drives popped itself out the array. The drive itself did not fail or degrade, but the drives did pop out of the array, which put two of the logical devices (the RAID 5 devices) in a degraded state. Now that drive is just sitting there, in a “Ready” state, doing a whole lot of nothing. I have been trying to diagnose and troubleshoot through the issue with HP, but they seem kinda baffled and claim that since its an Adaptec Storage Manager they don’t know a whole lot about it (even though they sent us the box with this controller and controller software installed). And Adaptec wants us to pay for support, and while that isn’t a big deal, the drive and array isn’t in a critical state and I’d like to avoid it.
I pretty much just need to verify that if I did some sort of the forced rebuild the controller would include this ‘Ready’ drive back in the array (which would set it to ‘Optimal’ Status like
the other 3) and actually start using it for data again. The Adaptec Command Line utility is called ‘aaccli.exe’, a program I can’t seem to find a user manual for in either our files or on the internet. Below I pretty much just copy and pasted an edited version of the last note I sent to the HP techs as we’ve been working through this problem.

We figured out that the drive basically just took itself out of the array for no real apparent reason that we can figure (other then the powersurge), and the logical drives (not the physical drives) are degraded because of it. I tried a couple steps last night that one of the HP techs suggested – some weren’t even real options and the ones I could try didn’t seem to do anything.
Basically I attempted to ‘Verify and Fix’ the disk the Adaptec Storage Manager. This removed the greyed out Physical disk re-appeared.
I then attempted to set the drive to fail, in an attempt to
