Hi TSMers... I'm working on a project to extract archived data from almost 2000 optical platters. The data needs to come out of TSM temporarily, be reprocessed, and eventually, loaded back into TSM. The problem is, I want to do this in the most efficient way possible, and I'm having a little trouble.
At this point in time, I'm getting the contents of individual volumes with a select statement, similar to a 'query content'. The only catch is, I want to read all the files on one side of the platter before switching it over to prevent the library from flopping platters back and forth, which eats into the aggregate transfer speed. Are their 'secret' tables or columns inside TSM that can tell me what the exact location of a file on a platter is? How does TSM know when it's mounting a platter if it needs to be flipped over for a retrieval? Any assistance, information, guidance, etc. will be greatly appreciated. Have a great weekend! -JD.
