We are currently using single length 3590 cartridge tapes and would like to move to using extended length tapes. We are running ADSM 3.1.2.40 on AIX. Can the two different tape length types co-exist in ADSM and if so how can this be accomplished? Does it entail defining a second virtual library with a separate device class etc. Would it be simple to manage? Is there any online documentation discussing this procedure?
