The V5R4 Licensed Internal Code requires more storage space than in previous releases.
The exact amount of this additional storage depends on which release is currently installed and which release is to be installed. If your server or logical partition does not have the additional space, the upgrade will stop during the installation of the Licensed Internal Code.
Use the Allocate Licensed Internal Code Space API (QLPALCSP) to find out if enough reserved storage is available, to allocate the additional space when necessary, and to correct any other possible errors. Enter the following text (where VxRxMx refers to the version, release, and modification of the Licensed Internal Code to which you are planning to upgrade).
CALL PGM(QLPALCSP) PARM('VxRxMx' 's')
