The following are indicated if the specifiedbit is ’1’.DSGFABUPDSGFAMIGDSGFADMPDSGFTHRSDSGFGBKUDSGGBNOLDSGFIMIGThis bit indicates that the data sets on the volumesin this Storage Group are eligible <strong>for</strong> automaticbackup.This bit indicates that the data sets on the volumesin this Storage Group are eligible <strong>for</strong> automaticmigration.This bit indicates that this Storage Group can beautomatically backed up using <strong>DFSMS</strong>hsm, or acomparable product. Dumping whole volumesinstead of individual data sets speeds up theprocess of restoring data sets to volumes.This flag indicates that thresholds have beenspecified <strong>for</strong> this Storage Group.This flag indicates that the maximum number ofdays between backups has been specified.This flag indicates that the maximum number ofdays between backups has no limit.This flag indicates that the data sets in this StorageGroup are eligible <strong>for</strong> interval migration.DSGFHTHR and DSGFLTHR must be specified.DSGFPSM This flag indicates systems features. See constants<strong>for</strong> DBCSYSFT in Table 26 on page 463.This field denotes the type of storage group to which the volumesbelong.
