Hello there,

 

I recently moved the array (with 10 drives of 10 tb each in a 2 x parity plus 8/eight from a pc case to a bigger case with 24 bays and from LSI SAS 9300-16i to a HBA SAS/SATA PCIE X8 TO 24 PORT SFF-8643 12GB/S EXPANSION CARD(it is a LSI 3224 model), the rest of the setup remains the same. 8 store 

Besides the initial 10 drives i attached another 8 x 6 tb sas drives.

 

After boot I keep get missing disk from array, in any position I put the drives on any of the 6 backplanes. I tried al combinations between drives, cables, I even tried to use another controller in addition(the initial one and another with 8 ).

 

Every time I get 1 or 2 missing drives from the original array and from 1 to 5 drives from the second batch of 6 tb drives not being seen.

 

So, I rebooted with only the initial drives of the array, rebuild the parity(by mistake) and added 4 more drives. I got again 1 missing drive from the original one(first ones of 10tb).

 

I rebooted with only 1 new drive, all good, upgraded the array to 8 x 10 + 1 x 6. I did it again with another 6 tb drive, all good, got 8 x 10 + 2 x6.

From here I have the same problem, i put in the third 6 tb drive, i get a missing drive from the 10tb ones, whatever the slot I used.

 

Any advice?

Do you mean 9305-24i or similar?

 

Please post the diagnostics.

I presume it is. Was bought refurbished, not too much info(pic attached).

 

Attached diagnostics before(1510) and after(1519) new 6 tb drive inserted. Also a pic.

Are you sure your PSU is up to the task as from your description it seems it might be related to how many disks you have plugged in?

First I used a 600w power. Then I thought may be a problem and switched to a 850w.

Same results. Anyway I monitored the power..from 80 to 240w...s-o no problem here..I think.

What about using power splitters - they can sometimes cause problems, especially if using SATA->SATA ones to split more than 2 ways.

I triple checked all of them, I am trying already 5 days in a row..everything I could...switched all the cables..the power..the position of drives in backplanes.

I would recommend contacting LSI to see if that is a genuine controller, AFAIK there's no SAS3224-24i model, that's the chip, the model should be 9305-24i or similar.
