Hi Luke,

That's terrific!

You know you might be able to tell ZFS which disks to look at. I'm not
sure. It would be interesting, if anyone with a Thumper could comment
on whether or not they see the import time issue. What are your load
times now with MPXIO?

Best Regards,
Jason

Jason,

Sorry, I don't have IM. I did make some progress on
testing.

The solaris 10 OS allows you to kind of lun mask
within the fp.conf file by creating a list of luns you
don't want to see. This has improved my time greatly.
I can now create/export within a second and import
only takes about 10 seconds. What a differnce compared
to the 5-8 minutes I've been seeing! but this not good
if my machine needs to see LOTs of luns.

It would be nice if there was a feature in zfs where
you could specify which disk the the pool resides
instead of zfs looking through every disk attached to
the machine.
