I suspect the reason you have 16 disk devices showing up is that you are running multipath. You will get one da device showing up for each different path, and if you're running a full multipath environment that's likely 4 paths per device, which would lead to the 16 disks (unless they're not the sizes you expect, but I would tend to suspect its a multipath artifact) To handle multipath you probably want to look at gmultipath(8). I'm not sure about READ/WRITE errors. You say they show up for 8 devices? Is it possible that the array is not true active/active on the controllers? Its possible that half the paths are going to a controller that is rejecting the I/O until the LUN fails over, but thats just a guess based on the error message. If you can look at the controller/bus/target/lun information from dmesg and see if you can spot a pattern about the path to the LUNs giving the error that may give a better idea about whats going on.
