Hello,

I wanted to test the new option ATA_CAM, but that would require a boot =
from another media (USB Drive/CD) and a zpool export/import
to update the vdev names. (actually it's shown as "path" in the =
zpool.cache file) because otherwise the system would refuse to =
open/mount
the pool.
But is that really necessary given the fact that all the devices are =
here, and have matching GUIDS to those in the zpool.cache file?
Shouldnt ZFS just import the pool?=20

In the current state what would one have to do to for example test =
ATA_CAM on a remote machine, where export/import from a rescue
media is not possible?

Thanks,
Niki=
