rndp6000-200 saga continues :-(
so my saga continues. I ahve all good drives now, with zero unrecoverable sectors. I was able to make a raid1 array no problems with it. XRAID. I got in another pair of identical drives, verif...
so I think I found the root cause of my issue 🙂
I verified everything was good, from PSU, to the drives, the CPU, to the connections... everything... except for one item, the memory.
I ran a memory test and the error count kept rising and rising took like 15 mins to get to 747 errors...
I pulled one module out and the errors went away.
I replaced them both with one of mine from the shelf and it verified perfection, 0 errors.
so I threw 6 256G drives in, started a factory reset (which never really completed before), and it went through first pass, no issues and really quickly.
I'm initializing the array right now 6x265G drives and it says it should only take an hour and a half... so far things are fully usable and operational even during the array initialization (resynch).
So it's looking good right now but I don't wanna jinx anything 🙂 I'll ahve to dig out 2x4Gig DDR2 ram sticks... I have a full tray of 4G ram, wish I could use those, there are maybe 36 sticks sitting there in the tray gathering dust on the cover ;-(

how can I verify the backplane in the 6000?
You can put create a volume on one drive, and then systematically boot the system up with the disk in each bay. Then run the disk test (on the volume settings wheel), and see what happens.

I run a quick SMARTCTL on the drives and the 1 Raw_Read_Error_Rate and 195 Hardware_ECC_Recovered were climbing through the roof.
issues always seem to appear when I start to use more than those first two bays in this 6000...
FWIW, that suggests it could be power related.

I did test creation of a new single drive volume in each bay, but I was not aware of that drive test. I have my test drive ready to go, it's a 2TB, I'll pop that into the 3rd bay and try the test.

I was told this unit had a new PS added into it less than a year ago. I wonder if they used a low powered supply? I'll have to pop it open and see. However, it's designed for 6 drives, I would think it can handle at least 3 without toppling over, but who knows right? 🙂
thank you again!
