Hello,
I happened to check my console randomly and I found a whole page of these errors. I can guesstimate what I think it means (failed or failing HBA) , but everything seems to be running "fine".
NOTE: these drives are part of a set of 12 in an external HP MSA60 (12 x 3.5" JBOD) with dual IO modules connected to a single LSI 3801e sas controller; I have each SAS port on the card going to one of the IO modules on the MSA60. Below is a snippit.
Any assistance to troubleshooting or a clue would be greatly appreciated.
P.S. I am running FreeNAS-9.3-BETA-201412051712.
