> How can you tell its wrong?
Because I've manually applied the service pack myself without incident (ie. no errors - the pack was applied "successfully") only to find that the status according to the properties page was missing components. "How can they be missing", I reason, "if I've just applied the whole thing successfully?". And when other machines with exactly the same CV software installed on them and exactly the same successful SP applied are not suffering from the same affliction?

If you applied the SP yourself and it went through without incident, then yes - I believe that it's fine. If you applied the SP via a push-install or let the automated download/install apply it, then you may need to check the log files to see if there were any problems at the time. But forget the tiresome log files - the easiest way to satisfy yourself is to manually install the SP again on the box that it reckons is sick. If it says that all of the updates have already been installed, then that's about it for the so-called "missing" components I reckon!
Note: Applying software updates (including service packs) will stop and restart the Simpana services - don't do it when anything CommVault is running on the box at the time. One good thing about working in the backup field of IT is that you can often work on these things during the day, since they usually run at night! Neat huh? [Until something goes wrong in the middle of the night and they call you out then :-( ]
