A suggestion I was given, but TSM support I think, was after changing ANYTHING on a drive...microcode...upgrades...whatever...always do an UPD DRIVE command against each one. TSM communicates with the drives and keeps track of the capabilities reported. All this does is refresh TSM's information. Now, if you delete the drive and add it back in you're OK. You can see some of this information with the SHOW LIBRARY command.

The only tapes that I had to set to "readonly" were those in a "filling" status. I have run the library approx 10 hrs/day since then and have not had any problems reading the old tapes. We have found a handful of tapes with media related errors that could not be written to once they had been reclaimed to scratch and we have been removing them from the library.

Has anyone done this? The existing cartridges can be read by the upgraded drives ( but noit written to ). I guess the question is will TSM use the newly defined drives when a call for a cartridge with existing data is made.
