The Save System (SAVSYS) command saves a copy of the licensed internal code and the QSYS library in a format compatible with the installation of the iSeries. It does not save objects from any other library. In addition, it saves the security and configuration objects that can also be saved using the SAVSECDTA and SAVCFG commands. Use SAVSYS before performing any type of system upgrade.
To save the system data on offline storage, the system writes a copy of the objects onto the media. The libraries and objects are not affected on the system. This command cannot be used to free any space occupied by these objects.
The history information for the data area QSAVUSRPRF in QSYS is updated with the date, time, and place where user profiles are saved. The history information for the data area QSAVSYS in QSYS is updated with the date, time, and place where the system is saved. The history information for the data area QSAVCFG in QSYS is updated with the date, time, and place where configuration objects are saved. The history information is not updated for the individual objects. To display the information in these data areas, specify the Display Object Description (DSPOBJD) command, and specify DETAIL(*FULL). Save the information from the display of QSAVUSRPRF for the location where the user profiles are saved.
When using this command, it is important to use the device on the system that is defined as the initial program load (IPL) device. The IPL device was defined by the service representative when the system was installed. If an IPL device is not used when using this command, then the system cannot be restored using the SAVSYS media (if densities or media types are incompatible).
Tips that involve the SAVSYS command:
- SAVSYS through batch jobs
- Run SAVSYS backup in a restrictive state to prevent errors
- Unattended full system save and IPL
