Draft Document for Review February 7, 2020 3:15 pm 8464ch09_Oper.fm Tokens are internal data structures that are used to track changes to the ownership, data, or  properties of each one of the existing logical volumes in the grid. Hot tokens occur when a  cluster attempts to merge its own token information with the other clusters, but the clusters  are not available for the merge operation (tokens that cannot merge became “hot”). Stolen volume  describes a volume whose ownership was taken over during a period in which  the owner cluster was in service mode or offline, if an unexpected cluster outage occurs when  the volume ownership is taken over under an operator’s direction, or by using AOTM.  For more information about copy mode and other concepts referred to in this section, see  Chapter 2, “Architecture, components, and functional characteristics” on page 13.  For more information about this MI function, see IBM Knowledge Center. Tasks window This window is used to monitor the status of tasks that are submitted to the TS7700. The  information in this window refers to the entire grid operation if the accessing cluster is part of  a grid, or only for this individual cluster if it is a stand-alone configuration. The table can be  formatted by using filters, or the format can be reset to its default by using reset table  preferences. Information is available in the task table for 30 days after the operation stops or  the event or action becomes inactive.  Tasks are listed by starting date and time. Tasks that are still running are shown at the top of  the table; the completed tasks are listed at the bottom. Figure 9-35 shows an example of the  Tasks window. Notice that the information on this page and the task status pods are of grid  scope. Figure 9-35 Tasks window: displaying the properties of one specific task  Chapter 9.
