Volume label fields

This topic describes the volume labels used in the open feedback area.

• IBM standard volume label (VOL1)
  The IBM^® standard volume label (VOL1) is 80 characters in length. The system uses it to identify the tape volume, tape volume owner, and security of the tape volume's contents. It is always the first block of data on the tape volume if the tape is a standard labeled tape.
• IBM standard data set label 1 (HDR1/EOV1/EOF1)
  Learn the details of IBM^® standard data set label 1 (HDR1/EOV1/TRL1) by reading this information. The IBM^® standard data set label 1 (HDR1/EOV1/TRL1) is 80 characters in length, and you use it to identify each data set.
• IBM standard data set label 2 (HDR2/EOV2/EOF2)
  The IBM^® standard data set label 2 (HDR2/EOV2/TRL2) is 80 characters in length and the program uses it to identify additional information about the data set.
• IBM standard user labels (UHL1-UHL8 or UTL1-UTL8)
  The IBM^® standard user labels (UHL1-UHL8 or UTL1-UTL8) is 80 bytes in length. The program uses them to identify additional information about the data set.
• Other IBM standard labels
  i5/OS™ only supports labels described above. However, it reads and ignores volume labels (VOL2-VOL8) and file labels (HDR3-HDR8) created on other operating systems.
• ISO/ANSI standard volume label (VOL1)
  The ISO/ANSI standard volume label (VOL1) is 80 characters in length. The program uses the label to identify the tape volume, tape volume owner, and security of the tape volume's contents. It is always the first block of data on the tape volume if the tape is a standard labeled tape.
• ISO/ANSI standard data set label 1 (HDR1/EOV1/EOF1)
  The ISO/ANSI standard data set label 1 (HDR1/EOV1/TRL1) is 80 characters in length and is used to identify each data set. The system records the data set label in ASCII.
• ISO/ANSI standard data set label 2 (HDR2/EOV2/EOF2)
  The ISO/ANSI standard data set label 2 (HDR2/EOV2/TRL2) is 80 characters in length and is used to identify additional information about the data set. The system records the data set label in ASCII.
• ISO/ANSI standard user labels (UHL and UTL)
  The ISO/ANSI standard user labels (UHL and UTL) is 80 bytes in length and is used to identify additional information about the data set. All information in the user labels is user data. The user labels directly follow the header/trailer group and can be up to any number of user labels per data set.
• Other ISO/ANSI labels
  ISO/ANSI standards also allow up to nine volume labels and up to nine header and trailer labels, but i5/OS™ will not create these "extra" labels. i5/OS™ will read and ignore these labels if created on another operating system.
