HDD Disk I/O Error

[DaPedda]

Hello Community,
I have since some days this problem: two harddisks bring me after 2h - 8h Disk I/O Error (after Server reboot) These two harddisks are connected to a HBA 9211-8i with unRaid 6.9.2

Interestingly, my array (connected to the internal SATA port) has exactly the same read performance as the two failed disks. I created a new disk configuration yesterday, but the error is back since this morning.
Please, who can give me a tip on how to narrow down the error further?

 

Thank you very much

Peter

Taking a guess it looks like sdm dropped offline and became sdp  However neither are showing up in the smart reports, so it appears that it dropped for good.  Reseating cabling is your first step.

Thank you for your help. I will move all Toshibas to a new case with new HBA cards and new cables this weekend. Then we will see. I'll report back and then close the post if all is well.

Last Friday I replaced the cable set and both HDD's were running all weekend, until 10:00 AM this morning.
Tonight I have now installed another COntroller, a Dell H200. Now I wait again and report back 😉

Conclusion: this was now my second HBA card which failed. With the Dell H200 and the old cable set I have no problems so far.
