There are several alternative procedures to perform an upgrade of Cray Systems Management (CSM) software. Choose the appropriate procedure from the sections below.
Follow one of these procedures when upgrading from CSM 1.4 to CSM 1.5 (regardless of patch version). (Additionally, in the unusual situation of upgrading from a pre-release version of CSM 1.5.0, then one of these procedure should be followed.)
There is no need to upgrade from CSM 1.4 to CSM 1.5.0, and then separately upgrade from CSM 1.5.0 to the latest patch release. The procedures in this section can be used to upgrade from CSM 1.4 directly to the latest patch release of CSM 1.5.
To perform an upgrade of CSM along with additional HPE Cray EX software products, see the Upgrade CSM and additional products with IUF procedure.
This is the most common procedure to follow, and it should be used when performing an upgrade from one HPC CSM software recipe to another.
To perform an upgrade of only the additional HPE Cray EX software products without simultaneously upgrading CSM itself, see the Install or upgrade additional products with IUF procedure.
To perform an upgrade of only CSM, see the Upgrade Only CSM procedure.
This option applies to CSM-only systems and systems which have additional HPE Cray EX software products installed, as long as those additional products are not also being upgraded. This is an uncommon upgrade scenario.
Follow one of these procedures when upgrading from CSM 1.5 to a newer patch version of CSM 1.5. (The one exception is in the unusual situation of upgrading from a pre-release version of CSM 1.5.0; in that case, follow the CSM major/minor version upgrade procedures).
If there are multiple patch versions available, note that there is no need to perform intermediate CSM 1.5 patch upgrades. Instead, consider upgrading to the latest CSM 1.5 patch release.
