Hi Ralf, Thank you for the suggestion. About half of the disks are reporting 1968-1969 in the "Soft Errors" field. All disks are reporting 1968 in the "Illegal Request" field. There don't appear to be any other errors; all other counters are 0. The Illegal Request count seems a little fishy...like iostat -E doesn't like the X4500 for some reason. Thank you again for your help.
