Checking the Hardware Requirements
Space Requirements for the File System
Make sure that there is enough temporary disk space available in the file system for the update. You need this free space for the SUM directory, the download directory, and directory DIR_TRANS. We recommend at least 40 GB free space for the SUM directory as well as for the download directory, and 20 GB for the directory DIR_TRANS.
As the space requirements depend on the product, see also the document with additional product-specific information for your update procedure to find information about the requirements. This document is referenced in the Master Guide or Upgrade Master Guide, respectively.
