You are probably not missing anything. I think its me that is missing something. I get from you that you do “something” on the HMC (something about a FTP server) I haven’t see it but it may be hidden I don’t use the HMC but maybe once a year. If you are saying you FTP what is on the DVD to the FTP started task on the MF I guess I am OK (but have questions) with that. The sticking point I am at is how does the FTP server on the MF even know about the HMC server? *assuming its magic* then does the FTP server on the HMC transmit the data to the FTP server on the MF (How????) and how does the FTP server on the MF know where to put the files that are downloaded and what naming conventions are used and what if you do not like them?\ I need a intro or something to explain to me what is going on so I can explain it to management as I am not understanding the slight of hand that is going on. Since apparently I need access to swap DVD’s as they are done how long (estimated) does it take? The reason I ask is that I have to have VP with me when I go near the HMC. I am sure he is not going to be happy sitting with me for hours on end. Sorry to be so pedantic but before I run this up the flag pole I need some basic information.
