Reverting storage snapshot on live filesystem is not possible.
Or any snapshot as far as that goes.
You will need to export the zpool and then restore storage snapshot and import the zpool.
No reboot should be required, unless it is a root zpool, then you will have to power off the ldom, revert, power on.
Is there a reason you are not using builtin zfs snapshoting ? It is much more flexible and a lot of things can be done on live systems (no need to export the zpool), but you will still need to stop the services which are using those filesystems.
Hope that helps

Hello,
Does anyone know how I can tell what disk are being not being used by a zpool?
For example in Veritas Volume manager, I can run a "vxdisk list" and disks that are marked as "online invalid" are disk that are not used.

mksnap_ffs
MKSNAP_FFS(8) BSD System Manager's Manual MKSNAP_FFS(8)
NAME
mksnap_ffs -- take a file system snapshot
SYNOPSIS
mksnap_ffs snapshot_name
DESCRIPTION
The mksnap_ffs utility creates a snapshot named snapshot_name.
The group ownership of the file is set to ``operator''; the owner of the file remains ``root''. The mode of the snapshot is set to be read-
able by the owner or members of the ``operator'' group.
EXAMPLES
Create a snapshot of /usr/home file system and mount the snapshot elsewhere:
mksnap_ffs /usr/home/snapshot
mdconfig -a -t vnode -o readonly -f /usr/home/snapshot
mount -o ro /dev/md0 /mnt/
SEE ALSO
chmod(2), chown(8), mdconfig(8), mount(8)
HISTORY
The mksnap_ffs utility first appeared in FreeBSD 5.0.
CAVEATS
The disk full situation is not handled gracefully and may lead to a system panic when no free blocks are found.
Every filesystem can have only up to 20 active snapshots. When this limit is reached, attempting to create more snapshots fails with ENOSPC,
and mksnap_ffs reports that it is ``out of space''.
