Ken,
The company I work for has a "certification process that is required" for applications that run on the servers. The requirements for Hotfixes/service packs are different than version increments. It is their requirement not my preference. I have applied SP1 for 9.0, and when trying to apply the tape driver updates for Intel, both versions 38 & 41 complain they need Hotfix 2. Apparently the driver update is looking for something that wasn't included in the Service pack 1.
I still need the link to Hotfix 2 for tapedriver installation.
