Zbx Firmware - IBM z13s Technical Manual

Maximums: Certain BladeCenter configurations do not physically fill up the rack with their
components, but do reach other maximums, such as power usage.

zBX firmware

The testing, delivery, installation, and management of the zBX firmware is handled in the
same way as z13s servers. The same processes and controls are used. All fixes to the zBX
are downloaded to the zBX Model 004 internal SEs and applied to the zBX.
The MCLs for the zBX are designed to be concurrent and their status can be viewed at the
z13s HMC.
9.6.1 zBX RAS and the IBM z Unified Resource Manager
The Hypervisor Management function of the Unified Resource Manager provides tasks for
managing the hypervisor lifecycle, managing storage resources, performing RAS, and using
the first-failure data capture (FFDC) features, and monitoring the supported hypervisors.
For blades that are deployed in a solution configuration, such as DataPower, the solution
handles the complete end-to-end management for them and for their operating systems,
middleware, and applications.
For blades that are deployed by the client, the Unified Resource Manager controls the blades:
The client must have an entitlement for each blade in the configuration.
When the blade is deployed in the BladeCenter chassis, the Unified Resource Manager
powers up the blade, verifies that there is an entitlement for the blade, and verifies that the
blade can participate in an ensemble. If these conditions are not met, the Unified
Resource Manager powers down the blade.
The blade is populated with the necessary microcode and firmware.
The appropriate hypervisor is loaded onto the blade.
The management scope is deployed according to which management enablement level is
present in the configuration.
The administrator can define the blade profile, and the profiles for virtual servers to run on
the blade, through the HMC.
Based on the profile for individual virtual servers inside the deployed hypervisor, the virtual
servers can be activated and an operating system can be loaded following the activation. For
client-deployed blades, all of the application, database, operating system, and network
management is handled by the client's usual system management disciplines.
9.6.2 zBX Model 004: 2458-004
z13s servers can only be in an ensemble that supports a zBX Model 004. When upgrading a
z114 or a zBC12 with zBX to a z13s server, the zBX must also be upgraded from a Model 002
or a Model 003 to a zBX Model 004.
