droopie Posted January 24, 2020 Share Posted January 24, 2020 lost a few drives due to rebuilds of the drives and it popping up with so many errors the drives get disabled. long story short im new to unraid and have 1 day on my extended trial. what is the best way possible in unraid to test if my sas cables are good? i have 4x 4 port sata to 1 port sas on 2x HBA's. i actually have 2 extra HBA's because i go a little crazy on bids on ebay. what is the best way to test the sata connection to the drives without causing issues? should i unassigned parity 2 then reassign it so it rebuilds and i can look for errors?

Decto Posted January 24, 2020 Share Posted January 24, 2020 (edited) If you're using LSI HBA's then there are fakes out there and any that aren't running firmware 20.00.07.00 are a risk of error due to bugs. If the cables are bad, you should see smart errors in attribute: 199 UDMA CRC error count but you get the same error from faulty card or firmware. You can trigger a manual parity check Edited January 24, 2020 by Decto Quote Link to comment
