One extent detail line is printed for each unique extent that is allocated to the cluster. The extent detail line shows the volume serial that contains the extent, the first and last absolute track address of the extent, the total number of tracks allocated to the extent, and the word INDEX if the extent contains only the index of a KSDS. Since embedded indexes share some extents with the data portion of the cluster, these common extents will not be duplicated for the index component. This should be kept in mind when the user is comparing an IDCAMS LISTCAT output to the CA Disk CLDATA report.
The extent limits are shown in cylinder and head format (cccc—hh) and are displayed in hexadecimal. The maximum number of extents that can be displayed is 32.
