Update Bundles (Service Packs)
Lenovo typically releases firmware in bundles called Update Bundles (Service Packs). To ensure that all of the firmware updates are compatible, you should update all firmware at the same time.
Update method terminology
In-band update. The installation or update is performed using a tool or application within an operating system that is executing on the server’s core CPU.
Out-of-band update. The installation or update is performed by the HOST BMC, collecting the update and then directing the update to the target subsystem or device. Out-of-band updates have no dependency on an operating system executing on the core CPU. However, most out-of-band operations do require the server to be in the S0 (Working) power state.
On-Target update. The installation or update is initiated from an installed operating system executing on the target server itself.
Update Bundles (Service Packs). Update Bundles (Service Packs) are bundled updates designed and tested to provide the interdependent level of functionality, performance, and compatibility. Update Bundles (Service Packs) are server machine-type specific and are built (with firmware and device driver updates) to support specific Windows Server, Red Hat Enterprise Linux (RHEL) and SUSE Linux Enterprise Server (SLES) operating system distributions. Machine-type-specific firmware-only Update Bundles (Service Packs) are also available.
