CommVault Simpana 9.0 SP2 recut DVD media is available on CommVaults Maintenance Advantage site in the ESD software download area. Media is marked as April 2011 and now includes SP2.
Of course, don’t go using these new DVD’s to install agents into an older version of Simpana. i.e. 9.0 SP1a for example, as you will have unexpected results and an unsupported configuration.
