Since I haven't seen any replies to this yet ...

To do the Unconvert and convert you run "delete archdescriptions nodename"
then "convert archive nodename"

Note that the document suggests contacting IBM support - you may want to do
that.

I'm not sure if converting the nodes to use the new DB structure will save
any space (I wonder if it will actually use more).  The new structure is
more efficient - when we upgraded to 3.7.4 archives became really slow - we
had to do the conversion for all nodes that run archives and then archives
sped up.

The process of converting uses lots of log space (if in rollforward) so
beware of that.  It also takes a while (depending on how much data is
archived per node).

Subject: FW: Unconvert Archive

Hi TSMers!
        The whitepaper
(http://www-1.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/WP100254)
states as one of the possible solutions to the DB growth driven by Archives
to:

"Unconvert the Node and then Convert the Node. This will force the node to
use the new table structure within the TSM Database. This new structure is
more efficient."

Does anyone know how to unconvert a node?

Also does anyone know how to change (not delete) the archive descriptions?
(in order to make them shorter and use less space in the DB)

Thanks in advance
Alex
