Zeunerts Posted September 19, 2018 Share Posted September 19, 2018 Recently bought 2x 8tb Ironwolfs and a RES2SV240 to expand my array (had 18TB before, LSI 9220-8i in IT-mode). Started preclears on both drives right after installation and everything seemed good. 30 hours later and both drives were done. Problem is they both showed UDMA CRC errors, 3 and 6 each. Researching tells me its normally a bad cable. I refitted everything, changed cables/ports, without success. Started extended SMART tests on 3 random drives from before and they passed without issues. Then I connected the new drives to the LSI9220 directly and did a new preclear (only zeroing). No errors.. Is the RES2SV240 faulty? Why didnt the other drives get UDMA CRC errors when connected through the RES2SV240? Is it because I have not written that much data to the old array after I installed the RES2SV240? Quote Link to comment
JorgeB Posted September 19, 2018 Share Posted September 19, 2018 9 times out of 10 the problem are the cables, but it can also be the expander or HBA. Quote Link to comment
Zeunerts Posted September 19, 2018 Author Share Posted September 19, 2018 Pretty sure I tried the same cable in both configurations (res2sv240 + LSI9220 and directly to the LSI9220). Only got errors when the res2sv240 was involved. Has to be that one then? Quote Link to comment
