I had a similar issue a few weeks back where there were so many predictive errors that I was certain the drive would fail. The errors stopped and the drive is fine. Some people think the drive MUST be replaced when predictive errors happen. I've been told by others to wait until the drive actually fails. I am with the latter group.

Subject: Predictive Disc Failure

I did a hot swap of a failed disc on my E4A today and all went well. A
few minutes after the new disc was in place and while raid was rebuilding,
the system threw a predictive disc failure on the new unit. I talked with
the support tech at IBM and they decided to ship us another replacement
disc. I've since checked back in on the system in question and there have
been no more failures reported and the raid protection is now reporting
that it is completely reset and fully functional.

If you were me, would you go through another disc swap on Monday?
