Good morning all!

I have a customer with a EMC VNX5300. Bus 0 Disk 0 was faulted, I replaced it with a replacement disk for this unit. However, after replacing and following the steps the UMS, the drive is not being recognized. I have never experienced this issue previously with any EMC product. It has always been a replace the drive and it rebuilds type of thing. Need help in trying to figure out what to do next.
