I just check servers from one of my customers, 2 hard drives have LED blinking green/orange. I suppose there is/will be an issue (doc said
The server is a PowerEdge R720xd. I used RAID 5, with 6 HD of 4TB each.
We record video on the logical drive (so we write a lot).
How should I procede to resolve the issue ? should I install Dell OpenManage (and so stop writing service) or procede from bios mode ?
What procedure should I follow to resolve that ? And how to procede with 2 HD ?
Green and amber generally indicate a predictive failure state on a driver. That means the drive is still functional and being used, but it has a lot of bad blocks and is expected to fail at any moment.
should I install Dell OpenManage
Yes, I would install one of our management applications to verify the issue.
And how to procede with 2 HD ?
That will depend on what the issue is and what the capabilities of the RAID controller are. If the drives are predictive failure then it is best practice to run a consistency check before replacing. Since there are two drives that need to be replaced and RAID 5 is n+1 you will need to replace them one at a time. You should not replace the second drive until the first has completed the rebuild.

What is a consistency check, how I do it (ok, found www.dell.com/.../perc---how-to-perform-a-check-consistency-using-openmanage-server-administrator )? What results should I expect ? Should I stop read/write actions on disk before this check ?
If I need to replace HD, should I do it in windows or in pre-boot tool ?
