Hi,
I have a problem with my Tapepool. We're running a TSM Server 5.5 on Linux, and i get often the message "not enough scratch tapes". We use a Christie T48 Library with 21 Tapes inside. The other 33 Tapes are outsourced to a safe. Every week we run a script to checkout and checkin tapes from the tapepool but TSM will only reclaim two tapes from the safe. This two tapes are checked in as scratch but two tapes are not enough. After one or two days i get always the message "not enought scratch tapes". A year ago he wanted to reclaim four or more tapes and now only 2.
It seems that tsm use not all the tapes from the safe, because some tapes were last used before some months. but the expiration is set to 14 days and the maximum allowed scratch tape parameter is set to 15 and 10 are used.
Has someone an idea that could help me?
Thanks in advance an sorry for my bad english.
