Upgrade notes for ClearCase on Linux and UNIX

Before upgrading Rational® ClearCase® on a Linux or UNIX operating system, review the system requirements on the IBM Software Product Compatibility Reports site for the version of the product that you have and complete any required upgrade planning tasks.

  • On Linux systems, verify that the required Linux software packages are installed.
  • If the Linux kernel on the Linux host where you are installing or upgrading Rational ClearCase is not compatible with the loadable kernel module included with ClearCase, MVFS rebuilds automatically. The build output is saved in the /var/adm/rational/ClearCase/log/install_mvfs.log log file. If you are running a Linux kernel that is compatible with one of the pre-built sets of modules, rebuilding is not required. For more information on how to rebuild MVFS, see technote 6467171.
  • If you are upgrading a ClearCase environment that is deployed in Solaris global and non-global zones, see the Deploying Rational ClearCase on Solaris zones documentation for information about installing and upgrading in Solaris zones.
  • See the documentation for more information about Rational ClearCase on the UNIX system and Linux.
