Hello Claire.
That feature is in OpenSolaris but not regular Solaris 10
(http://www.opensolaris.org/os/community/zfs/version/10/):
This page describes the feature that is available with the ZFS
on-disk format, version 10. This version includes support for the
following feature:
- Devices can be added to a storage pool as "cache devices."
These devices provide an additional layer of caching between main
memory and disk. Using cache devices provides the greatest performance
improvement for random read-workloads of mostly static content.
This feature is available in the Solaris Express Community
Edition, build 78.
The Solaris 10 10/08 release includes ZFS pool version 10, but
support for cache devices is not included in this Solaris release.

I could
use
some assistance on this case. I searched this error on sunsolve &
although it did spit out a million things I have not found anything
that pinpoints this issue.
T5240 w/solaris 10 5/09 U7& kernel patch #141414-10
# zpool upgrade -v is at version 10 so should have cache availability
cust is trying to add a cache device to a zpool but it's failing
ERROR: can not add to zpool name pool must be upgrade to add these
vdevs
He's also trying to add the cache device into a guest domain, it's
running on the domain controlled by ldm. Can this be done? Looks like
he's at all the versions he needs to be to get this done. Is there a
bug? I appreciate any assistance that can be provided.
Thanks!
