For your Entertainment:

Today I upgraded my NBU 5.1 MP6 environment to 6.0 MP4, and boy what an adventure it was!
In brief, our environment has 1 AIX master, 2 AIX medias and 1 Windows media. (1 of the AIX medias is behind a firewall)

To start out the day, there was a nice, accidental delay on the start time.
After that the install actually went quite smoothly; all the software installed successfully and the Console came up.
Then it was time to do the old nbpushdata ...
The master and 2 non-firewalled medias ran nbpushdata without a problem.
The firewalled media, of course, decided it couldn't communictate with the EMM server.  Fortunately it turned out to be a network config error (they'd setup the port communication in the wrong direction) and it was easily corrected.

After it ran, however, things took a turn for the worse.
Mysteriously, a bunch (close to 1000) of media appeared in the TLD(0) media listing.  The section should have remained empty after having moved the existing media to Standalone.  And the media info was OLD; at least 3 years old!

Fortunately, 2 hours on the phone with Symantec (and a lot of text editing) resolved this issue (seems like the media server had a bunch of old info lying in wait for some reason and it just made a lot of duplicate info which needed to be deleted).

On top of all this, the robotic library also refused to be available for inventorying and listed all drives as AVR.  This was due to a fun little step (#5 in the Installing NBU 6.0 Guide) that directed me to run /usr/openv/volmgr/bin/driver/remove_ovpass; not really a problem there, but there was no follow up to re-create ovpass again at all!

Other than that (and a few more minor things that need to be ironed out), the upgrade was a good experience.  The excellent features in 6.0 are well worth the hastle of the upgrade.

Exciting, to say the least!
