I am setting up a NAS with 8 known-good 8TB WD Red drives from a previous NAS. When I configure RAID 6 across these drives my (untested) LSI MegaRAID 9265-8I starts beeping and reports that that drive is bad. However, when I run WD's LifeGuard Diagnostics it reports that all of the SMART tests pass.
MegaRaid failure event as reported by MegaCli:
Code: 0x00000191 Class: 2 Locale: 0x02 Event Description: Diagnostics failed for PD 18(e0xfc/s7) Event Data: =========== Device ID: 24 Enclosure Index: 252 Slot Number: 7
Things I have tried so far:
- Erasing the "Bad" drive completely
- Setting the "Bad" status to "Good" and reconfiguring the array
- Swapping the SFF and sata cables (the same drive failed in any position)
Anyone know what else I should try or if I am likely looking at a bad drive or a bad RAID controller?
