Larry, 

If you use the ALMS feature of the 3584 library, then you are locked in to the 
library doing the cleaning. 
An ALMS is a pretty nice feature to be using. 

PS Can I ask why you have two single partition libraries instead of one with 2 
partitions. Unless they are  in different locations. And maybe a third 
partition for test use.

Subject: [ADSM-L] IBM 3584 Tape Cleaning

Those of you who have the IBM 3584 tape libraries - please weigh in on 
pros/cons of using either the Automatic Cleaning method of the host library or 
the Tape cleaning management method of the TSM server.  We are configuring  two 
3584's to replace our four 3583 libraries.  Our environment is TSM 5.3x server 
on AIX  5.3 with LTO2 drives and LTO2 tapes in the libraries with each library 
configured as it's own single partition.
