Hi aram,   please perform a Backup before starting this.   To clear the Foreign flag from the drive, for example, you will go into OMSA(or any other Tool you prefer)  ... Storage, PERC , Information/Configuration link at the top of the page, Clear Foreign Configuration from the drop-down menu of available tasks.  Do this ONLY when the system is running fine and there is only one drive showing Foreign.  If you have more than one disk showing Foreign, then you have to Import the Foreign Config.  Anytime there is a config/timestamp different from the controller's config, it will show Foreign, so if it is only on a single disk, clear it and move on. I would test your original drive, as it may not be bad.  Make sure your system firmware (BIOS, ESM, RAID) and RAID driver are up to date ... this can help prevent Foreign configs.     regards Martin
I have a R720, one of the disks was showing an increasing number of: "A disk media error on Disk 2 in Backplane 1 of Integrated RAID Controller 1 was corrected during recovery." I ended up finding a similar drive (slightly different model, but same size, speed, specs, cache) and replaced the drive. Using the controller menu at boot I replaced the drive, and watched it rebuild the RAID 5. I just checked the {!} remains on the idrac overview as well as the "physical disk" pages. I'm wondering if I'm seeing an old warning that has never cleared out or I'm having the same exact warnings on a second disk? How do clear the warning so I can see if it comes back? I did try: Doesn't look like there is an actual issue from the controllers point of view.
