A drive failed on my Pegasus R4.
I've swapped it for a new one, but the rebuild process failed near the beginning and the drive was shown as "dead".
I forced it back online with promiseutil, but it seems no data gets copied onto it (even though the whole array, logical drive and physical drives show as 'ok'). Both options in the UI utility (passthru and unconfigured) are un-ticked and can't be enabled, with the drive now being "configured".
How do I get the new drive to its original (unconfigured/passthru) state again?
