Dell PowerEdge R710 PERC H700 replace failing mirrored drive

http://www.ahfx.net/weblog/182

  • Remove bad disk (hot swap so no need to power down the machine)
  • Replace with a good disk of same size or larger
  • It automatically rebuilds the array
  • Once the rebuild goes to 100% it still showed in degraded state
  • Clear logs
  • Clear alert log
  • Do a global rescan
  • Everything shows a good status and running without problems.

I was very nervous about pulling drives on the fly, but everything went well.
