Thanks for the info.

Does anyone have any performance benchmarking procedures or utilities that can 
be used to verify tape drive performance ? We are running TSM 5.3.5.2 on AIX 
5.3 ML4 using a SL8500 using ACSLS.

TSM manages tape block size itself, through the device driver.  Avoid
interfering with that.
