I'm surprised google is unable to find the zpool man page available at
https://illumos.org/man/8/zpool.  Maybe you should try different search
tool, or simply run `man zpool`?

zpool scrub

Yes.


>From the zpool man page:


     zpool scrub [-s | -p] pool...
             Begins a scrub or resumes a paused scrub.  The scrub examines all
             data in the specified pools to verify that it checksums correctly.
             For replicated (mirror or raidz) devices, ZFS automatically repairs
             any damage discovered during the scrub.  The zpool status command
             reports the progress of the scrub and summarizes the results of the
             scrub upon completion.
