I've had a SuperTrak EX8650 in use for quite a while now, running a Raid 6 array of 5 disks (4 TB each) with 1 assigned hot-spare (but no BBU). It uses the latest available firmware (from 2011 or 2012: V1.10.0000.01).
First, some background and a description of what's happened: A few days ago the controller suddenly stopped working: it started beeping (two short consecutive beeps, repeating). After that the system froze on the first access to the array. This happened a few more time, but I was able to back up some of the data (about half) as it worked for abouit a day and a half. Unfortunately, I can no longer get the system to boot without it starting to beep for more than a minute (if at all, usually beeping starts during the controller post screen now).
Now it looks like the controller itself is dying: When I disconnect the drives and enter the controllers own BIOS, I can't access the Log, it just tries for a good while and eventually reports error 0x80. I've entered the bios once with drives connected (enduring the incessant beeping), and I wasn't able to do anything useful either. I did get a message similar to "Internal error in firmware raid core" or something similar.
If the exact message matters, I can try that again.
My actual question:
- I assume I can access the array normally if I get a hold of a replacement controller of the same type?
- The problem is, these are relatively hard to get here (germany/europe)
- and/or expensive for just reading the data basically once...
- But can I also access the array with a similar controller but of slightly different type?
- For example, would a EX8350 work? It's much more easily available.
- Of course I'd need some different cables? But other than that?
- I don't see a firmware of similar age as mine (those for EX8350 are older), and that concerns me as one of the (only) changes was supporting drives over 2TB (and sectors above 4k).
- Are there any other (simple/cheap) options?
