Migration triggers

Migration is automatically triggered when the HSM for Windows client detects that space usage reaches the high threshold. You can also start threshold migration manually, any time that space usage is greater than the low threshold.

The IBM® TSM HSM Monitor Service monitors space usage on an interval that you configure. Migration is triggered when the IBM TSM HSM Monitor Service detects a high threshold of space usage, and continues until usage reaches the low threshold. The HSM for Windows client can decrease the interval when space usage approaches the high threshold. Nevertheless, if space usage increases rapidly and is not checked frequently enough, it is possible that space usage can exceed the high threshold before migration begins.
