Not sure where to start. I'm getting errors reading things from everywhere.
I actually have two controllers in this workstation.
1 LSI MegaRAID 9271-8i
2. LSI MegaRAID 9265-8i
The first controller has 8 2.5" disks in RAID5 as a working production drive
the second controller is running RAID0 with 2 3.5"s as handoff storage to keep redundant data by copying the Acronis backups so there are duplicates, then I send those to an external 8tb drive for further redundancy
I started noticing that MegaRAID Storage Manager would drop off one of the 2.5" drives. Then another.. What was strange is it wasn't the same drives each time.
When this happened it would either come up the drives were unconfigured bad, foreign configured etc. it changed. with RAID5 if I lose two drives that should be total data loss aka the whole array. But i never had to rebuild the arrays, just put the drives back online, or import the configurations again and resume. Once in a great while it would rebuild one of the drives but that was rare
As time went on I couldn't figure it out. Ended up replacing wires including power, reseating cards and drives, Changing drives from one box to another and can't get a consistent read.
Finally I took the card out and left the drives offline.
I started using just the RAID0 with the two 3.5" drives. After a month or so the same thing happened. Same exact problem.
I had dialed it down to assuming it was the card with the bigger array on it. Then when I pulled that card and the drives, same issue. Now the same issue propagated to my smaller drives on the 9265
Can anyone think of what I should be looking at? I find it hard to believe my cards have both gone bad, but I'm lost. Now both cards are not working and I'm running without backups.
Thoughts?
