[gpfsug-discuss] GPFS on ZFS?

Hi Chris

As I understand, GPFS likes to 'see' the block devices, even on a  
hardware raid solution such at DDN's.

How is that accomplished when you use ZFS for software raid?
On page 4 I see this info, and I'm trying to interpret it:

General Configuration
...
* zvols
* nsddevices
   – echo "zdX generic”


Thanks
Jaime
