CX4 Disk Copying off to hot spare
Why is my disk copying off to the hot spare if there are no indications of a drive failure? Should I have the disk replaced that its copying off from?

Hi,
Usually proactive Hotspare (copying to Hotspare) happened when the drive is nearly failing., This need an investigation to check why proactive hotspare is happening..., I would request you to generate SP collects and open a chat with CLARiiON team to review the SP collects.

As I was reading your reply, the drive failed. I have opened a case with EMC and have a new drive on the way.

If the drive reaches a certain level of errors, it will proactively copy the data to a new disk, and then fail the original drive. The proactive copy is much less overhead on the array/performance than a rebuild operation, as such proactive copy is preferred.
