Talking to jp at Redhat, the above output of the e.25 kernel system is only showing the fibre channel attached storage, not the cciss device. /proc/stat is not showing anything as its define to stop at major number 99 and cciss uses higher major numbers, in this case 104. I am having the same problem on a Compaq/HP DL 380 with cciss drivers on kernels e12, e16, e25 and e35. No data returned from iostat -d. An iostat -x will return other data that I am not needing. This appears on 7.3 as well. Versions of sysstat tested include 4.0.1, 4.0.3, 4.0.7 and 5.0.1. The disk_io: line in /proc/stat is blank if that makes any difference.
