CL command support for media formats
Use these commands to save and restore data. And, read about the restrictions for the ISO 9660, High Performance Optical File System (HPOFS), and Universal Disk Format (UDF) media.
- ISO 9660
- You can use IBM® i restore commands to restore data from ISO 9660 media. This is true only when the media was correctly mastered from a save image on tape. There are some restrictions on which optical commands are supported for ISO 9660 media.
- HPOFS
- IBM i save and restore commands can be used to save and restore data on HPOFS optical media. Refer to Saving and restoring optical media for more information about save and restore operations to HPOFS volumes. There are no restrictions on which optical commands the system supports for HPOFS media.
- UDF
- IBM i save and restore commands can be used to save and restore data on UDF optical media. There are some restrictions on which optical commands are supported for UDF volumes. For example, the system does not support Work with Optical Directories (WRKOPTDIR) and Work with Optical Files (WRKOPTF) commands. The Display Optical (DSPOPT) command has some restrictions when used for UDF volumes. You should use the integrated file system commands Work with Object Links (WRKLNK) and Display Object Links (DSPLNK) instead of the optical commands.
Some optical commands have no meaning when used with certain optical media formats. No support exists for other commands with certain optical media formats. This table lists all of the volume-related optical commands and the media formats to which they apply.
