Upgrading an IBM Storage Ceph cluster using cephadm

As a storage administrator, you can use the cephadm Orchestrator to upgrade to the latest version of IBM Storage Ceph by using the ceph orch upgrade command.

The automated upgrade process follows Ceph best practices.

• The upgrade order starts with Ceph Managers, Ceph Monitors, then other daemons.
• Each daemon is restarted only after Ceph indicates that the cluster will remain available.

For information about upgrade paths, see Supported upgrade and crossgrade paths.

Before starting to upgrade IBM Storage Ceph, see Installation and upgrade requirements.

The storage cluster health status is likely to switch to HEALTH_WARNING during the upgrade. When the upgrade is complete, the health status should switch back to HEALTH_OK.
