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?

  • The answer is yes. You should boot into the lifecycle controller to see that, but it means a downtime. That's how it's going. – batistuta09 Mar 13 '17 at 10:50
  • @batistuta09 thanks for the reply. Can i take disks offline from lifecycle controller? – Threedor Mar 13 '17 at 11:37
  • Yup, via Hardware Configuration Wizard. – batistuta09 Mar 13 '17 at 11:44

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.

  • It uses the PREC H710 adapter – Threedor Mar 13 '17 at 11:17
  • I think the MegaRaid tool may well help you out. A link below: broadcom.com/support/download-search/… Select Software & Tools, Then the Windows version of the MegaRAID Storgae Manager. P.S. Username and password are the same as your Windows Login Details. – Mike Smith Mar 13 '17 at 11:42
