100 IBM Power 720 and 740 Technical Overview and Introduction
need to be updated. You should upgrade the support level of the HMC to be consistent with
the support that is provided on the servers to which it is attached. In a dual HMC
configuration, both systems must be at the same version and release of the HMC.
To determine the HMC machine code level that is required for the firmware level on any
server, go to the Fix Central website and 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. See the Fix Central site:
http://www-933.ibm.com/support/fixcentral/
With HMC code V7R7.7.0 (SP1), the HMC supports Mozilla Firefox 7 through 10 and
Microsoft Internet Explorer 7 through 9.
HMC RAID 1 support
HMCs now offer a high-availability feature. Starting from HMC 7042-CR7 RAID 1 protection
will be enabled by default. This feature is enabling data redundancy using two physical disk
drives.
RAID 1 is also offered on both the 7042-CR6 and the 7042-CR7 (if the feature was removed
from the initial order) as an MES upgrade option.
Blade management
The HMC gives systems administrators a tool for planning, virtualizing, deploying, and
managing IBM Power System servers.
With the introduction of HMC V7R760, the HMC can now manage IBM BladeCenter Power
Blade servers. This management includes support for dual VIOS, live partition mobility
between blades and rack servers, and management of both blades and rack servers from a
single management console.
Comparison of 7042-CR6 and 7042-CR7 HMC models
The 7042-CR6 was withdrawn from marketing in December 2012. For your reference,
Table 2-29 lists a comparison between the 7042-CR6 and the 7042-CR7 HMC models.
