The diskpool was full, but high migration is 5%. A low highmig threshold could easily start off migrations that run just one file then quit, especially if there are large files...but how did you fill the disk pool with such a low percentage for the high mig threshold?

Today I came in the office and customers complained about failing backups. I checked the TSM server and noticed that the diskpool was full. Migration was running, but only two processes at the same time. A migration starts, migrates a file an then completes successfully, another one starts, migrates one file and finishes again and so on. The storagepool has migproc=10 and the nextpool is not collocated, but only two are running and they keep on finishing after just migrating one file! I was able to lower the storagepool usage manually by issuing move data commands against the physical diskpool volumes. This way I was able to move all the data from them manually, but I don't understand why migration is behaving like this. Has anybody seen this before? Thank you very much for your reply in advance!
