I am refering to 3.2 Sys admin manual which does not have the -altreadhost 
option in the man page. I was just curious, do I need to specify the media 
server as -alreadhost as well as -shost ?
In my duplication scripts I am not specifying the above two opetions (-shost 
and -alreadhost). Basically I am looking for some performance improvement in  
duplications. [ I have a mster and a media server, media server controls all 
the drives ]

TIA
