In BS2000/OSD-BC V9.0 and higher a pubset can be provided with additional storage space which a net server makes available as Net-Storage. This enables files from pubsets to reside either on local pubset disks or remotely on a Net-Storage. BS2000 OSD/BC V10.0 and higher supports both the file type BS2000 and node file on Net-Storage.
The ORIGINAL-SUPPORT operand can be used to specify that files from a Net-Storage (STORAGE-TYPE operand) are to be imported. Importing of Net-Storage files can also be restricted to the file type BS2000 or node file (FILE-TYPE operand). By default all Net-Storage files are imported irrespective of the file type.
The NEW-SUPPORT operand can be used to specify that files are to be stored on a Net-Storage when they are imported. Importing files on to a volume of NETVOL volume type is possible only in BS2000 V21.0A or higher. This must be especially taken into account when working with shared pubsets.
BS2000 files from public volume or Net-Storage files of the type BS2000 cannot be imported to a Net-Storage as node files. Net-Storage files of the file type node file, whose SAM structure has been saved, can also be imported to Net-Storage or a public volume. During this process, their file type can be changed. In contrast, net storage files of the file type node file, whose SAM structure has not been saved, can only be restored on a Net-Storage volume and with their original file type node file.
