Hi All, Environment: - TSM v3.7.3 - IBM7337 library (15 slots) with around 10 tapes for onsite tape pool status full, a cleaning tape and 3 to 4 scratch tapes - Currently there are around 40 nodes defined in TSM - a few more nodes are coming and backup data volume on existing nodes is expected to grow, so there will be move media operation soon - there is only one onsite tape storage pool defined and that is having collocation off To improve restore performance, I am thinking of turning on collocation for onsite tape pool. But there are more nodes than number of slot in library, should I define maxscratch=N and let TSM to collocate data on the 40 nodes within the N tapes. Keep monitoring tape usage and adjust N whenever necessary. Any suggestion on the setup and the number N? Thanks in advance. Regards, Eric Tang
