Offload System Onloading and Restoring Datasets (TSIDONL)
Chapter 13. Disk Space Management 13-27
Onloading and Restoring Datasets (TSIDONL)
TSIDONL onloads or restores datasets back to disk. It can also be used to produce a report
listing the datasets contained on the offload tape. TSIDONL functions are selected using
UPSI values.
You can onload a dataset from an offload tape only. TSIDONL assigns the dataset a current
relative version based upon its absolute generation number. You can restore a dataset from
either an offload or a backup tape. For sequential disk versions identified in the BIM-EPIC
catalog, the restore function assigns the dataset version number 1.
The Start Track 1 feature is required to automatically access a dataset that has been offloaded.
Specify a starting track or block address for this feature using the STRTRK option.

Value Function
000 Onloads all datasets from the offload tape. No control statements are read.
010 Onloads datasets selected by control statements only.
100 Restores all datasets from the offload or backup tape. No control
statements are read.
110 Restores datasets selected by control statements only.
xx1 Creates the report only. No datasets are onloaded or restored. No control
statements are read.
xxx1 Assumes uncataloged input tapes are in new offload format. (See note
below).
0x0x1 Prevents onloading of a dataset that has been scratched from the BIM-EPIC
Catalog. (See note below).
UPSI xxx1, which only applies to tapes containing offload or backup data for sequential disk
versions identified in the BIM-EPIC catalog, should only be used when the tape volume(s)
accessed are not cataloged AND they were created using the new proprietary high performance
offload system (BIM-EPIC 4.15 and higher). The following events could cause this situation:
•
The tape volume was PURGEd from the catalog
