I have a poweredge T420 with two "Predictive failure" disks. Configuration is RAID-5. I'm hoping to hot-swap the disks 1 by 1 by after marking each drive as failed. In order to see the rebuild progress i was going to use "Open Manage" But i have problems with "Open Manage" which is not solvable at the moment (Contacted dell about this & still waiting for a fix) Is it possible to use "Lifecycle Controller" for the above mentioned purpose?
Do you know which controller you are using in the T420? I have user the 'MegaRaid' tool for Perc 5i / 6i / H200 and H700 controllers from Dell and found that it works really well for my purpose (And I can monitor the rebuilds and failures etc). I know it is re branded now to AVANGO but if you hunt around you can still download and use it.
I hope that helps you out.
