Think I have a controller card/connectors going bad again.

 

Here are the errors I see in the log:

Whatever link ATA-9 is on is failing?

May 13 09:37:08 Tower kernel: sas: ata9: end_device-1:0: dev error handler
May 13 09:37:08 Tower kernel: ata9.00: ATA-9: WDC WD30EZRX-00D8PB0,      WD-WMC4N0F1LJZN, 80.00A80, max UDMA/133

 

Whatever link ATA-10 is on is failing?

May 13 09:37:08 Tower kernel: sas: ata10: end_device-1:1: dev error handler
May 13 09:37:08 Tower kernel: ata10.00: ATA-8: WDC WD20EADS-00S2B0,      WD-WCAVY0922071, 01.00A01, max UDMA/133

 

Whatever link ATA-11 is on is failing?

May 13 09:37:08 Tower kernel: sas: ata11: end_device-1:2: dev error handler

 

And then I also see this SATA link being limited to 1.5Gbps; this must be on a bad connector/SATA cable maybe?

Only the last item is an issue. All referenced to dev error handler are normal.

Try a new SATA cable for disk1.
