Set your tape drives to CLEANFREQ=NONE and RTM at > http://www-1.ibm.com/support/manager.wss?rt=4&org=ssg&doc=570001038&aid=1 This URL yields an empty document. You probably meant it to be http://www-1.ibm.com/support/manager.wss?rt=4&org=ssg&doc=S7000103&aid=1 Anyway, on page 86 this document states: "Whenever a drive requires cleaning, it alerts you with a message on the library operator panel or host console. ... Host cleaning Host/Application maintained and activated is the default condition. Host cleaning enables the server to detect the need to clean an Ultrium Tape Drive and to control the cleaning process. The cleaning cartridge must be stored in one of the available storage slots within the library. For more information, see the section about cleaning in your application software documentation. Manual cleaning Manual cleaning requires that you use the Move Media command from the library s operator panel to insert a cleaning cartridge into the library to perform cleaning on one or more of the Ultrium Tape Drives (see Move Media Dialog on page 106). " To me this means, that you - either watch the library's operator panel, and response to a drive's need to be cleaned by inserting a cleaning cartrige and using the Move Media Dialog, - or let the application software, i.e. TSM, control the cleaning. I strongly prefer the second method. And I'm sharing Tom� Hrouda's concerns: Our 3583, which is in production since Feb. 2001 and currently receives about 60 GB data per night, has never cleaned a drive, at least according to the "Cleanings Left" number yielded by "QUERY LIBVOL". I just started a cleaning cycle by hand ("CLEAN DRIVE"), just to verify that this changes the "Cleanings Left" number. It does. -- Reinhard Mersch Westfaelische Wilhelms-Universitaet Zentrum fuer Informationsverarbeitung - ehemals Universitaetsrechenzentrum Roentgenstrasse 9-13, D-48149 Muenster, Germany Tel: +49(251)83-31583 E-Mail: [EMAIL PROTECTED] Fax: +49(251)83-31653
