There is an open issue/bug with ZFS and EMC PowerPath for Solaris 10 in x86/x64
space. My customer encountered the issue back in April 2007 and is awaiting
the patch. We're expecting an update (hopefully a patch) by the end of July
2007.
As I recall, it did involve CX arrays and trespass

How much fun can you have with a simple thing like powerpath?
Here's the story: I have a (remote) system with access to a couple
of EMC LUNs. Originally, I set it up with mpxio and created a simple
zpool containing the two LUNs.
It's now been reconfigured to use powerpath instead of mpxio.
