IBM SY44-5902-05 manual Work with disk units

Note: There are two copies of some Licensed Internal Code on the load-source disk unit. It is the IPL type (A or B) that selects the Licensed Internal Code level with which your system will run.

vRebuild Licensed Internal Code

This option allows you to rebuild the Licensed Internal Code. On RISC systems, this means combining free space for all nucleus and service Load IDs.

vDisplay Licensed Internal Code

This option allows you to display the following:

–Replaceable unit information (code or object modules)

–Fix information

–Product information

The Fix information option allows you to display the status of the Licensed Internal Code fix (if it is permanently or temporarily applied). For more information on displaying fixes, see “Displaying Licensed Internal Code fixes” on page 224.

vWork with free space

This option displays the space available for storing new modules on the system and allows you to combine the space that is used.

vRemove fixes

To remove Licensed Internal Code fixes, if the PTF is a delayed PTF, the system must be running on the copy without the changes (type A IPL). Removing these changes causes the system to load the primary copy over the changes in the changed copy of Licensed Internal Code.

Immediate LIC PTFs can be removed while running a type B IPL.

vMake fixes permanent

To make Licensed Internal Code fixes permanent, the system must be running on the copy with the changes. When these changes are made permanent, they are loaded into the primary copy of the Licensed Internal Code.

vDisplay status (F6)

Press the F6 function key on the Work with Licensed Internal Code display to view the history log.

For more information on PTFs, see “Displaying Licensed Internal Code fixes” on page 224 and the system operation information.

This option allows you to do the following from the partition from which DST was entered:

vWork with disk configuration.

–Create and update the disk configuration.

–Display the logical structure (disk unit and auxiliary storage pool (ASP) information).

vWork with disk unit recovery.
