If an SM pubset is recovered that has a corrupt control volume set, the information determining whether the pubset is a LARGE_OBJECTS pubset must also be recovered.
The LARGE_OBJECTS attributes, therefore, are not only stored in the SVL of the VOLRES of the control volume set, but also in the SVLs of the other volume sets in the SM pubset.
The “Exclusive import of a pubset with pubset conversion” function is offered for recovery purposes.
This uses a special IMCAT to create an SF pubset from a volume set in order to enable access to data stored on a volume set, regardless of the validity of the control volume set. When it is converted, the SF pubset inherits the LARGE_OBJECTS properties of the
SM pubset.
When the SF pubsets taken from the volume sets are combined to form an SM pubset using SMPGEN, the LARGE_OBJECTS properties are transferred, as described in the section“Generating SM pubsets with SMPGEN”.
