Hmc Code Level; Hmc Connectivity To The Power8 Processor-Based Systems - IBM Power System E850C Technical Overview And Introduction

2.13.3 HMC code level

When using any HMC with the Power E850C servers, the HMC code must be running at
V860.10 level or later. The minimum firmware level for the Power E850C is V860.10 or later.
When using the Power E850C server to access the cloud-based HMC Apps as a Service, the
HMC code must be at a minimum level of V860.
If you are attaching an HMC to a new server or adding a function to an existing server that
requires a firmware update, the HMC machine code might need to be updated to support the
firmware level of the server. In a dual HMC configuration, both HMCs must be at the same
version and release of the HMC code.
To determine the HMC machine code level that is required for the firmware level on any
server, access the Fix Level Recommendation Tool (FLRT) on or after the planned availability
date for this product:

FLRT identifies the correct HMC machine code for the selected system firmware level.
Note: Access to firmware and machine code updates is conditional on entitlement and
license validation in accordance with IBM policy and practice. IBM can verify entitlement
through customer number, serial number electronic restrictions, or any other means or
methods that are employed by IBM at its discretion.

2.13.4 HMC connectivity to the POWER8 processor-based systems

POWER8 processor-based servers, and their predecessor systems, that are managed by a
hardware or virtual appliance HMC require Ethernet connectivity between the HMC and the
server's service processor. In addition, if dynamic LPAR, Live Partition Mobility, or PowerVM
Active Memory Sharing operations are required on the managed partitions, Ethernet
connectivity is needed between these partitions and the HMC. A minimum of two Ethernet
ports are needed on the HMC to provide such connectivity.
For the HMC to communicate properly with the managed server, eth0 of the HMC must be
connected to either the HMC1 or HMC2 ports of the managed server, although other network
configurations are possible. You can attach a second HMC to the remaining HMC port of the
server for redundancy. The two HMC ports must be addressed by two separate subnets.
