Before Release 24 you had to remove the physical disk to replace in order to force a rebuild.  During the rebuild phase, the RAID group was "degraded" and at risk.

Hello all!  I have been charged with swapping out a failed hard disk located in a CX3-80 and I need some advice.  When my boss found out that the disk was bad he swapped out the failed disk (146GB, 10K RPM) for a disk that had been in a CX4 (146GB, 15K RPM) and it seems to have worked fine.  Well, now we have the correct replacement drive and he wants me to swap the CX4 drive for the new replacement but I do not want to just physically eject the working drive as I think that it could cause issues.  Please help do this the correct way.
