Volume lists with UDF media

 

This topic describes volume list information specific to Universal Disk Format (UDF) media.

More than one file in a multi-volume set can logically span volumes, but only one file per volume can span to the next volume in the volume list. The last volume in the set accepts additional save requests if space is available. The system maintains the continued flags for spanned files.

• Volume1 (Sequence#=1, Starting volid=Volume1, Last volume in set=No)

  • File1 (Continued from previous volume=NO, Continued on next volume=NO)

  • File2 (Continued from previous volume=NO, Continued on next volume=NO)

  • File3 (Continued from previous volume=NO, Continued on next volume=YES)

• Volume2 (Sequence#=2, Starting volid=Volume1, Last volume in set=No)

  • File3 (Continued from previous volume=YES, Continued on next volume=NO)

  • File4 (Continued from previous volume=NO, Continued on next volume=NO)

  • File5 (Continued from previous volume=NO, Continued on next volume=YES)

• Volume3 (Sequence#=3, Starting volid=Volume1, Last volume in set=No)

  • File5 (Continued from previous volume=YES, Continued on next volume=YES)

• Volume4 (Sequence#=4, Starting volid=Volume1, Last volume in set=Yes)

  • File5 (Continued from previous volume=YES, Continued on next volume=NO)

  • File6 (Continued from previous volume=NO, Continued on next volume=NO)

1. Space permitting, additional saves are allowed to Volume4.

2. A restore operation begins on the volume that contains the first occurrence of the specified file. For example, you can restore data from File4 on Volume2 without processing Volume1.

3. The volume set for UDF media described in this section is not related to the volume set or multi-volume support that is defined in format specifications for UDF (ECMA 167 3rd Edition or UDF Revision 2.01). Support for volume sets as defined by these specifications is not currently provided by i5/OS^®.
