Last weekend I had to replace one harddisc in a RAID 1 on a PERC/5i controller because it reported it as failed.
After replacing the disc it worked for 5 days and then the controller started complaining about the new disc:
# megaclisas-status -- Controller informations -- -- ID | Model c0 | PERC 5/i Adapter -- Arrays informations -- -- ID | Type | Size | Status | InProgress c0u0 | RAID1 | 465G | Degraded | None -- Disks informations -- ID | Model | Status c0u0p0 | WD-WMAYP4753240WDC WD5003ABYX-01WERA1 01.01S02 | Failed c0u0p1 | S13TJ1KQ503997 SAMSUNG HD502IJ 1AA01110 | Online, Spun Up There is at least one disk/array in a NOT OPTIMAL state.
So now I'm a bit suspicious about the controller, it's hard to believe that such a new disc fails after so little uptime, or is it? What can I do to diagnose the source of the problem? And is there a way to just reset the status the controller thinks the disc is in?
