The Restore Stgpool and Restore Volume commands are very closely related.
Under the covers, most of the code is the same. The major differences are
o Restore Stgpool restores primary files that have previously been marked as
damaged because of a detected data-integrity error. This is done regardless of
whether the volume has been designated as destroyed.
o Restore Volume allows you to specify the volume name(s) rather than using
Update Volume to designate the destroyed volume(s).
For restoring a small number of volumes, the Restore Volume is more convenient,
particularly if you are not interested in restoring damaged files on other
volumes. For restoring damaged files or a large number of destroyed volumes,
Restore Stgpool is preferable.
