Hello, I have a 51158 USB 3.0 & eSATA to 5x SATA RAID Adapter.
It is attached to a MacPro via USB3 and is connected to 4 2tb drives. The MacPro is running OS X 10.9.3.
I created a 4 member RAID5 array and one of the drives was marked as bad and the array is in degraded condition.
I have removed the old drive and put in a new one.
Can anyone tell me how to set the new drive as a member of the array so it can rebuild?
Thanks

As far as I understand this is an automatic process once the new drive is replaced with the faulty one.

Are you using an GUI to monitor the drives?

Yes, I am using the RaidManager app for Mac, GUI_Mac_v0.09.58.

The new drive shows up as "Unreleased" and not a member of the RAID5 set. No autorebuild starts.

The only options I see in the advanced section are Delete RAID and Create RAID.

Is there a command line version of the RAID manager?

I've not seen a command line version.

What setting do you have for the EZ pin?

Did you place the new drive in the same port as the previous failed one?

Yes, the controller labels it as Drive 2 and we ejected the bad drive and inserted a good one. It showed up as Unreleased and nothing else happened. We've been through a number of reboots, unplugging, replugging, power cycling etc.

This seems very odd and not what the unit is supposed to perform.

If you place the new disk in the spare slot and turn the EZ switch to off does this rebuild?

I would only try this if your data is safe, as worst case changing the dip switches once the array is build will cause it to wipe!

Thanks a lot for your help. It turns out this card might not be a Lindy card (I wasn't there for the install), though it uses the same chipset and looks the same, the firmware and behavior might be different.

Here's what worked in the end, starting with the EZ in the OFF position, powered down the enclosure with the card, replace "bad" drive with good drive, set EZ to ON position, hold down the recessed SET button and power on. The card emits a 10 second beep and the rebuild begins. After the rebuild was done, eject drive, power down unit, set back to EZ OFF, power up, and the card emits a beep, RAID5 array is no longer degraded.

Note: as you said, one should have a good backup before trying anything like this, and note that this worked on a similar card by a different supplier, so not sure it will also work on the 51158
