Chapter 17 System Management 347
Applying System Patches
A system patch is an XPF (Xsigo Package File) that provides a focused fix for a
specific file or files in the Oracle Fabric Interconnect file system. A patch tends to be
smaller and more manageable, and allows for applying hot-fixes to the Oracle Fabric
Interconnect. Through patching, a new file can be installed on the Oracle Fabric
Interconnect in a typically less intrusive manner, which also allows the Oracle Fabric
Interconnect to use the new file without requiring you to completely upgrade the
entire Oracle Fabric Interconnect to a new version of XgOS. In some cases, a system
upgrade to a new version of XgOS might still be required, but with system patching,
more flexibility is introduced into how images are installed and managed on the
Oracle Fabric Interconnect, and how features and fixes are applied to the XgOS.
Note – Host drivers, InfiniBand expansion switches, and Ethernet expansion
switches (for example, the ES48) do not yet support patching.
Obtain Patch Files
Patch files are made available through the Oracle Xsigo Support Portal or My Oracle
Support (http://support.oracle.com/). To obtain one or more patches, contact
Oracle Customer Support. When the patches are downloaded to the Oracle Fabric
Interconnect, you will extract them.
Review Patch File Contents
Patch files are named patch-<number> where number is an internal identifier that
is applied by Oracle. When the system is patched, an existing file on the Oracle
Fabric Interconnect is replaced with a new file that you have obtained from Oracle.
