This procedure describes how to upgrade Cray Systems Management (CSM) software on a CSM-only system without additional HPE Cray EX software products installed.
After the upgrade of CSM software, the CSM health checks will validate the system before doing any other operational tasks like the check and update of firmware on system components.
Note: If problems are encountered during the upgrade, some of the topics do have their own troubleshooting sections, but there is also a general troubleshooting topic.
If IMS image creation CFS jobs fail, see Known Issue: IMS image creation failure for a possible workaround.
On some systems, Ceph can begin to exhibit latency over time, and if this occurs it can eventually cause services like slurm and services that are backed by etcd clusters to exhibit slowness and possible timeouts.
See Known Issue: Ceph OSD latency for a workaround.
See Prepare for Upgrade.
The upgrade of CSM software will do a controlled, rolling reboot of all management nodes before updating the CSM services.
The upgrade is a guided process starting with Upgrade Management Nodes and CSM Services.
See Validate CSM Health During Upgrade.
Check and update firmware if not already at the correct versions. Make sure the latest version of the HPE Cray EX HPC Firmware Pack (HFP) has been installed. Follow the procedures for updating firmware with the Firmware Action Service (FAS) document Update Firmware with FAS.
After completion of the validation of CSM health, the CSM product stream has been fully upgraded and configured.
