Pubset activation is started with the IMPORT-PUBSET command. A basic requirement for this is the hardware connections to the volumes concerned.
A further requirement is that an MRSCAT entry exists for the pubset and contains the following information:
pubset ID
pubset type (SF or SM pubset)
control volume set ID (only for SM pubsets)
All further information can either be specified at the time of activation or determined from the storage locations themselves and stored in the appropriate MRSCAT entries. The MRSCAT entries assigned to the pubset must remain intact during the pubset session. The definitions in the entries can be modified, but the changes are only effective for the next pubset session unless they are activated with the pubset reconfiguration functions.
