ABSTRACT:
Tracks of meta data are cleared in a storage server by allocating task control blocks for executing associated tasks in parallel. Throttling and recycling of task control blocks is provided to efficiently use memory and processing resources. Under the control of a master task, task control blocks are allocated to different hierarchical levels of storage resources in the storage server, such as a logical subsystem level and a subordinate volume level. The task control blocks are not deallocated from memory until there are no further tasks to process.
