Hi I ahve recently configured TSM 3.7.0. I have a problem in 3590 E11 autoclean operation. In the device class I have defined cleaning ASNEEDED flag but yet it flashes CLEAN mesg on the control panel but TSM does not clean the drive automatically. Can anyone help me out ? Also, I want to check-in one 3590 cleaning tape that has only 75 usages left, however in it does not allow me to check in the cleaner tape with Cleaning Left parameter 75. I have to put 100 only, which is not the correct value. Can some one explain me ? AIX version is 4.3.3 on RS6000/SP2 with TSM 3.7.0 with TPD for Informix and IBM 3590 E11. Please let me know if you need any more details. Regards Sachin Ganu IBM Global Services ( India )
