Lately, I have been noticing lots of "Clean Me" messages in ERRPT of the TSM AIX system, for the 3590E1A drives it uses.
So, I started looking into the setting on the 3494, which controls cleaning. Currently, it is set to clean by usage (65). Upon digging through the "IBM TotalStorage Enterprise Tape - A Practical Guide" Redbook, I found the paragraph: We recommend that drive cleaning be based on a drive request. Use time-based cleaning only if drive usage is very low. For 3590 tape drives, use a value of 999 mounts to perform cleaning based on a drive request rather than an initiated library. So, what do you use to control the cleaning cycle for your 3494/3590 drives ? Do you follow the above recommendation ? Is this a global recommendation that can be applied to *ALL* 359x drives ? Inquiring minds want to know ?
