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!

ps: I finally learned how to quote in this board! yay!! 🙂

you know, this unit does appear to function ok with 2 drives in it... and things seem to go south with more than three... maybe it IS power related? I'm running the diesk test with my test drive in bay3 right now. We'll see wht comes of that... but I have a feeling you may have hit the nail on the head there with the power related issue.
Any tests for that? I ahven't opened it, but I assume it's a standard AT style PS? smaller form factor it seems, but are the connectors standard? I can plug in a 600watt supply on the side and see if that makes a difference... I could buy 6 100GB drives and throw them in as my test drives... or heck I probably have 6 laying around here on a shelf for testing LOL

what wattage SFX PSU is required for these? 500watt sufficient? or should I look at a 750?

It shipped with a 300 watt supply.
The original 300W supply has more 12V than most typical ones of that rating, and it's what powers the drives. I always recommend you go with at least 350W in a replacement, and I usually go with 400 myself. Higher will, of course, work.
so this is weird. the disk test completed, but it appears like the entire unit shut down but the blue power light on the button was still lit up. fans were off, drives were not spinning any more, nothing. even tapping on the power button did nothing. tapping several times did nothing, and I could not get to it via the GUI either.
I had to press and hold the power button and it powered down after like 3 seconds.
weird? or a sign the PSU is on the fritz?
well, disk test completed, now it wont boot past 97%.... no matter what slot I put this disk in LOL this was the working good disk with no errors ;-(
I am about giving up over here ;-(
