TSM Server 5.5, 6.1, & 6.2 Bug

I figured I best share with you all a bug I have experienced with TSM Server version 6.2.2 that has resulted in the TSM instance core dumping. The problem stems from TSM being unable to mount a scratch tape with, in our case, a TSM storage agent. When the mount fails it seems TSM lists an internal server error then core dumps a few seconds later.  The fix is in 6.2.3 and higher. It also affects 5.5 and 6.1 versions, check this technote for further details.

Warning: This update has a bug also concerning Data Domain that causes errors if the defined VTL has more than 4400 slots. So when we upgraded the server to fix the LAN-Free bug we inadvertently encountered this bug.

Update: Here is the APAR listing for the Data Domain VTL slot bug in TSM 6.2.x
