There are multiple scenarios for installing CSM software which are described in this documentation with many supporting procedures.
There are two ways to install the CSM software. There are some differences between a first time install which must create the initial configuration payload and configure the management network switches, whereas a reinstall can reuse a previous configuration payload and skip the configuration of management network switches. The first time install will check and then may update firmware for various components whereas the reinstall will check and indicate that no firmware update is required. There are two different ways to use the LiveCD, either from a RemoteISO or a USB device, which are described in Bootstrap PIT Node. There are a few places where a comment will be made in a procedure for how one of the scenarios needs to do something different.
First time Install
Reinstall
The two paths merge together after configuration of the management network switches to do later actions the same regardless of the starting point in the workflow.
After completion of the firmware update with FAS and the preparation of compute nodes, the CSM product stream has been fully installed and configured. Refer to the 1.5 HPE Cray EX System Software Getting Started Guide S-8000 on the HPE Customer Support Center at https://www.hpe.com/support/ex-gsg for more information on other product streams to be installed and configured after CSM.
See Install CSM for the details on the installation process for either a first time install or a reinstall..
The upgrade from Shasta v1.4.2 (including CSM 0.9.3) to Shasta v1.5 (including CSM 1.0.1) is supported. This process will upgrade the Ceph storage software, then the storage nodes, then the Kubernetes master nodes and worker nodes, and finally the CSM services. The management nodes are upgraded using a rolling upgrade approach which enables management services to continue to function even as one or a few nodes are being upgraded.
See Upgrade CSM.
There is no direct migration from Shasta v1.3.x releases to Shasta v1.5. However there is a supported path.
Migration from v1.3.x to v1.4.0
The migration from v1.3.x to v1.4.0 is described in the Shasta v1.4 documentation. Refer to “1.3 to 1.4 Install Prerequisites” and “Collect Data From Healthy Shasta 1.3 System for EX 1.4 Installation” in the HPE Cray EX System Installation and Configuration Guide 1.4 S-8000.
Upgrade v1.4.x to v1.5
An upgrade from the previous release (Shasta v1.4.x) is supported with this release.
