Most of these define what is going on. So I'm not sure what you mean when you say what is causing them.

05 24 00 - Invalid req. Means that a command was issued that was invalid.
Example would be issue a move media command from a slot OR DRIVE THAT DOESN'T HAVE MEDIA IN IT????

The NO SENSE and Blank check indicate that the tape is full. And needs to unload/load a second tape. (Tape Spanning) on a backup.

The media erros, Write,read, or unrecovered read could be an indication that the drive needs to be cleaned. Or that the media has an issue.

Not Ready Cleaning cartridge installed. Says that a cleaning operation is taken place.

So for the most part these are informational messages being logged by comvault.

Not sure I answered your question. But hopefully it gives you a little bit of insight.
