Managing the storage hierarchy in an environment with SF pubsets

HSMS implements its functions in a three-level storage hierarchy. In this storage hierarchy the disk and tape storages are subdivided according to their availability, access time and the costs (see section "Storage hierarchy").

Storage level S2

Storage level S2 need not be explicitly created in HSMS. The S2 level is always defined in any HSMS system.
The default value for volumes requested for write requests to S2 can be defined by means of

//MODIFY-HSMS-PARAMETERS DEFAULT-HSMS-STORAGE=*PAR -
// (S2-DEVICE-TYPE=<c-string>)

HSMS supports volumes of the class “TAPE”, LTO magnetic tape cartridges and emulated tape devices of ETERNUS CS Data Protection Appliances (see section "Level S2 volumes").
