I have an IBM 9672-R26 with 3 LPARs defined. On the product LPAR I have TSM server 5.2.1 and the equivalent TSM client. All 3 LPARs have roughly the same number of OMVS files and file sizes. The other LPARs are for test and development. It takes about 10 to 15 times longer to backup the production files as oppose to the test and development file. For example I installed the latest JAVA PTF, roughly 200 MB and it took about 1.5 hours to backup the production LPARs to the server running in the same LPAR. It took only 5 minutes to backup the test and development JAVA changes from their LPAR. It backups many times faster going across LPARs as opposed to backing up itself. Is this normal? Is there something wrong with my configuration? This is a backup to a disk storage pool. The test and development LPAR were clones of the production LPAR. The operating system is z/OS 1.4.
