Volume list contents

 

Volume lists allow a single save and restore operation to use many pieces of optical media to complete the requested operation.

Information relating to optical volumes that are a part of a save and restore volume list may be displayed using the Display Optical (DSPOPT) command.

Volume list information fields:

Continued from Previous Volume flag

  • This field applies only to UDF media.

  • This flag indicates that the save and restore file is continued from the previous volume in the volume list.

  • Only one file on a given volume can have this flag set on.

  • You can use the DSPOPT DATA(*FILATR) command to display this flag.

Continued on Next Volume flag

  • This field applies only to UDF media.

  • This flag indicates that the save and restore file is continued to the next volume in the volume list.

  • Only one file on a given volume can have this flag set on.

  • You can use the DSPOPT DATA(*FILATR) command to display this flag.

IPL Capable flag

  • This flag indicates that the Save System (SAVSYS) command created this volume and that you can use it for D-Mode IPL.

  • You can use the DSPOPT DATA(*VOLATR) command to display this flag.

Last Volume in Volume List flag

  • This flag indicates that the volume is the final volume in a volume list.

  • For High Performance Optical File System (HPOFS) format volumes, the system does not allow save files that are unrelated to the volume list on the final volume. The remaining capacity does not affect this situation. UDF volumes do allow unrelated save files on the volume if sufficient free space exists.

  • You can use the DSPOPT DATA(*VOLATR) command to display this flag.

Starting Volume ID

  • The volume ID of the first volume in a multiple volume set in a volume list is located in the starting volume ID field. For UDF volumes, the volume list might contain several different save files. Consequently, this field does not specify the starting volume of any given file that is contained in the set.

  • You can use the DSPOPT DATA(*VOLATR) or DATA(*FILATR) command to display this flag.
