The various tape libraries I have used have not needed umounting.  Bacula 
does some sort of SCSI lock on the drive it's using, but the library & 
robot are more or less "free".  So long as bacula has unloaded the tape 
you're interested in, which it will have done if it's moved onto backing 
up to a different one, you can eject your magazine, do tape moves, etc as 
much as you want.  ie take out the tapes you want to off-site, put in 
replacements... 

When you've finished with those, do an update slots so bacula knows what 
it has in the library.

So I think you can skip steps 3 and 6.

Btw because most of my libraries have two drives, I have put a locking 
wrapper around mtx, to stop myself from accidentally interfering with the 
robot at the same time as bacula.  Probably paranoid but just in case...
