To roughly generate a TSM macro file to vary on any stgpool volumes
which are found to be offline, you can do like:

 SELECT 'VARY ONLINE' as "           ", -
 VOLUME_NAME from VOLUMES where -
 VOLUME_NAME like '/%' and STATUS='OFFLINE' > /tmp/tsmfile

Tailor per your site.
Remove column headers from the file, then run as a macro, if anything
viable in it.
