Are the errors all on the same drive? Are drives being cleaned automatically? Check to see if any drive cleaning messages were issued just after the write errors on the drives. I know the system is only 6 months old, but is the firmware and microcode all up to date?

It is appreciated! I have a client with a TS3200 less than 6 months old. They received a media attention indicators on their library last week. On investigation I found 2 volumes with write_errors. I moved the data off of them and retired them. The tapes were purchased when the library was implemented so they are relatively new as well. I manually cleaned the drives with the on board cleaning cartridge. Now today I see 6 more volume marked bad by the library interface and they too have write_errors in TSM. I guess I wonder Why this started all at once? Qhat the ramifications(other than the obvious ones) of these write/read errors are? When/how are these generated and when should action be taken?
