A space manager program operates in all hosts sharing a plurality of storage subsystems, such as a DASD (direct-access storage device), magnetic tape, random-access storage, and other forms of external storage units. Each space manager requires that when a space management task is instituted, there be a reasonable assurance of successful completion. Accordingly, in a plural host environment with limited host-to-host communications, a common control block related to events occurring in the space management process coordinates activity of the various space manager programs operating in the various hosts. The common control block includes pointers to task control blocks for interlocking activity of the various space managers.
