64 IBM Power System S822 Technical Overview and Introduction
򐂰 PowerVM management enhancements:
– Enhanced and simplified HMC management of PowerVM virtualization enables
automation and simplifies the setup and operation of PowerVM
– Improved “no-touch” VIOS virtualization management enables complete virtualization
administration from the HMC
򐂰 Virtualization-oriented capacity and performance monitor and performance statistics
These performance statistics can help you understand the workload characteristics and to
plan for capacity
򐂰 HMC command to initiate a Remote Restart operation
This removes the requirement of VMControl for the PowerVM Remote Restart function.
򐂰 Updated web browser support
– Mozilla Firefox ESR 17 and 24
– Microsoft Internet Explorer 9 through 11
– Google Chrome 31
If you are attaching an HMC to a new server or adding function to an existing server that
requires a firmware update, the HMC machine code may 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 required for the firmware level on any server, go to
the following web page to access the Fix Level Recommendation Tool (FLRT) on or after the
planned availability date for this product. FLRT will identify the correct HMC machine code for
the selected system firmware level.

2.9.2 HMC RAID 1 support
HMCs now offer a high-availability feature. The new 7042-CR8, by default, includes two hard
drives with RAID 1 configured. RAID 1 is also offered on the 7042-CR6, 7042-CR7, and
7042-CR8 (if the feature was removed from the initial order) as an MES upgrade option.
RAID 1 uses data mirroring. Two physical drives are combined into an array, and the same
data is written to both drives. This makes the drives a
mirror image of each other. If one of the
drives experiences a failure, it is taken off-line and the HMC continues operating with the
other drive.
HMC models
To use an existing HMC to manage any POWER8 processor-based server, the HMC must be
a model CR5, or later, rack-mounted HMC, or model C08, or later, deskside HMC. The latest
HMC model is the 7042-CR8. For your reference, Table 2-20 on page 65 lists a comparison
between the 7042-CR7 and the 7042-CR8 HMC models.
Note: Access to firmware and machine code updates is conditioned on entitlement and
license validation in accordance with IBM policy and practice. IBM may verify entitlement
through customer number, serial number electronic restrictions, or any other means or
methods employed by IBM at its discretion.
