Patch installer

The patch installer patchinstall is a tool that is provided to install patches on an existing cluster.

The patch installer includes functionality to query a cluster, check contents of a package and compatibility with the cluster, and patch or roll back a cluster.


The patch installer installs all patches and never modifies configuration. A partial distribution (FP or fix) can only be installed by the patch installer.

The LSF installer installs full distributions and can modify configuration. The LSF installer incorporates the patch installer so the process of updating the files is the same as the patch installer. However, the LSF installer should be used to install an update because the update may require configuration changes that lsfinstall can do automatically.

The LSF installer may change with each update. You should not install a new update using the old lsfinstall program or install.config template; make sure your installers match the version of the distribution you are installing.

Patch installer accessibility

For clusters version 7.0 or earlier, you must obtain the patch installer separately, and run the patchinstall command from your download directory.

For clusters version 7 Update 1 (7.0.1) or later, the patch installer is available under install directory under the LSF installation directory. This location may not be in your path, so run the patchinstall command from this directory (LSF_TOP/9.1/install/patchinstall).

Order of installation

If you have to install multiple patches, start with the most recent update, which includes all previous fixes. Install on all UNIX hosts to bring the whole cluster up to date. Then, install fixes or fix packs as needed.

Quiet install

For lsfinstall, enable quiet install by the LSF_QUIET_INST parameter in install.config. Quiet install hides some messages.

Unattended install

The silent install option is used for automated installations.

For lsfinstall, enable unattended install by the SILENT_INSTALL parameter in install.config. Unattended installation hides all messages and means you want to accept the license.

Windows-UNIX clusters and Windows clusters

If your cluster has both Windows and UNIX, patch the UNIX hosts in the cluster using the patch installer. Patch the Windows hosts using Windows tools.

The Windows patch files should be installed in order from oldest to newest on every Windows host if you have more than one to install.

To install a Windows patch, double-click the .msp file for the OS you want and follow the wizard. You may be asked to reboot after installing. Follow the Windows prompts if applicable.


You can also install silently.
