EqualLogic PS6000 - Lost Blocks Detected

I have a EqualLogic PS6000 FW version 5.2.5 that has a warning "RAIDset lost blocks detected."  I used the CLI and ran the command to see how many lost blocks and its showing 1300.

I read in another post that it is not recommended to erase the lost blocks because some FW versions need a script ran.  I'm currently out of warranty, and wondering if you could provide some assistance?  Am I safe deleting the lost blocks?  Is there a command I can use to accept the warning?

Best Regards
