Chris,
Just to make sure the x4100 config is similar to your Linux system, can
you verify the default setting for disk write cache and make sure they
are both enabled or disabled. Here's how to check in Solaris.
As root, run "format -e" -> pick a disk -> cache -> write_cache -> display
Not sure how to do it on Linux though!
