Hardware Management Console (HMC)
• Single console for POWER5 servers
– Pre-installed embedded OS
– Supports local consoles, including 5250
– Web-based System Manager enables local or remote
management for HMC control and status
• LPAR and CUoD
– Now configured and managed via HMC
• May 2004 - announce HMC Limits
– One HMC can manage a maximum of two i5 Servers
– One i5 server can be managed by only one HMC
– 40 partitions per HMC
• July 2004 - announce HMC Limits
– One HMC can manage a maximum of 16 Power5
Servers (any mix of i5 or p5 servers)
– A single Power5 Server can be managed by two
HMCs (providing redundancy)
– Maximum of 64 partitions per HMC
• Replaces primary partition and improves system
resiliency

Why a Hardware Management Console (HMC)?
•
©
Servers are becoming more virtualized
– Operating systems will continue to have less direct visibility
and control over “real” server hardware
– A place for hosting advanced platform management
applications, outside of the operating systems, to do:
 Server configuration prior to operating system deployment
 Service when operating systems are unavailable
 Coordination of platform-related operations across
multiple operating system images, in an independent
security model
 Presentation of virtual operating system consoles
– These functions should have common user and programming
interfaces, independent of any one operating system
 Supporting both local and remote operation
 A common delivery vehicle, which enables IBM to deliver
more function, more quickly

When is an HMC Required on i5 System?
• Systems with multiple Partitions (LPAR)
• Systems with Capacity on Demand
• Systems with redundant service processors
• Systems yet to be announced (High-end)

What is an HMC
• Based on xSeries server technology, built upon pSeries HMC
device
• Runs an IBM-provided GUI console application
– Not to be used with customer applications
7310-C03
(desktop)
– Helps ensure a more stable console environment
• Required
– To create/modify partition – not to run it
– For Capacity on Demand functions
• Not required to operate the partition
• Saves the cost of typical primary partition
• 5250 interface for optional i5/OS console provided
• Remote console by other workstations through HMC
7310-CR2
(rack)
– 5250 interface via Telnet5250 client
– Windows/Linux/AIX Client interface for HMC interface
• At August 2004 iSeries GA, one HMC can support a maximum of
64 partitions across up to 16 Power5 servers.

HMC – More Details
• Based on xSeries server technology
– Minimum HMC configuration includes: 1 GB memory, 40 GB disk, DVDRAM, 10/100/1000 Mbps Ethernet port, diskette drive, etc
– Selectable options for HMC’s display, keyboard, etc (ordered separately)
– HMC connects to POWER5 service processor which has two dedicated
HMC ports. The ports are Ethernet ports. (Different from the two generic
10/100/1000Mbps Ethernet LANs.)
• Standard HMC maintenance support is CRU. Suggest upgrading
support to IBM On-Site Repair to be more consistent with POWER5
server’s support agreement.
• HMC not used on earlier iSeries servers
• non-HMC i5/OS consoles are still supported
• High availability suggestion: attached two HMCs to critical Power5
servers or redundancy.

HMC “network” possibilities
• Local HMC: any physical HMC that is directly connected to the system it
manages via a private network. Usually the first or only local HMC in your
private network is a DHCP server in your private network and a DHCP
client in your open network.
• Remote HMC: any HMC used to remotely access another HMC or
managed system. Remote HMCs are usually present in an open network
Remote HMCs can also be local HMCs.
• Web-based System Manager Remote Client: usually a PC installed with
“Web-based System Manager” software. Use this PC to access other
HMCs remotely. Web-based System Manager Remote Clients can be
present in private and open networks. You can perform most management
tasks using the Web-based System Manager Remote Client

HMC User Interfaces and Access
• Local GUI
– Starts automatically whenever the HMC is started
– Requires user login prior to access
• Remote GUI
– Uses an installable standalone remote client application (WebSM Client)
• Windows (NT,XP) or Linux
• Downloadable as an installable application directly from the HMC, using a
web browser
– Also supported from one HMC to another, or from AIX 5L
– Can be SSL secured through public/private key files
• Generate on the HMC, and transfer to client systems
• Local Command Line
– Launched from a right-click menu option on the HMC desktop
– Restricted to a set of supported HMC commands
• Remote Command Line
– Accessed through encryption-protected Secure Shell (SSH)
– Key files can be set up and exchanged to avoid password prompts
• Very useful for automation and scripting without human intervention

PAGE 10
Web-based System Manager Remote Client
• Two remote clients install options available:
– Web-based System Manager Remote Client
– Web-based System Manager Remote Client for Java Web Start
– Either client works the same after installation
– You can access your HMC remotely by installing the WebSM client on your PC
workstation
– The WebSM client provides flexibility by allowing you to manage your system
from virtually anywhere you have a PC. Up to 5 remote clients can be logged in
simultaneously
– SSL security is optional
• Remote console, i5 OS using TN5250 to HMC and share the HMC console session
• Some tasks not performed using the remote client
– These tasks include determining the level of HMC code, restarting the HMC
interface, and configuring System Manager Security for certificate authority or
viewing overview and status information.
• For more information: eServer Information Center....

HMC Security
• Restricted Shell
– Provides access to supported HMC command line functions
– Accessible remotely through SSH enabled client
– Also accessible as a command prompt window on the HMC itself
• Granular User Access Controls
– Define Task and Resource Roles that define accessible lists of user
tasks and resources (systems, partitions, etc)
– Assign roles to users to define their access rights
– For example, access could be limited to a single partition
• Network Security Firewall Controls
– Define which HMC network services should be accessible on which
physical network interfaces
– For example, limit remote WebSM or SSH access to a single interface,
or none

HMC Electronic Connections to IBM
1. Local Modem
– This option enables you to send problem information and system data to
your service provider using the modem on your HMC. You may want to
select this option if the following are true:
•
•
Your HMC does not have access to a high-speed Internet connection.
You do not have any I5/OS logical partitions with high-speed Internet
connections
2. Internet VPN
– This option enables you to send problem information to your service
provider using a high-speed Internet connection on your HMC
– This is the fastest connection option available on the HMC, but some
environments restrict this type of connectivity for security reasons. Before
you select this option, be sure your company's security policy permits this
type of connection

HMC Electronic connections to IBM (cont’d)
3. Connecting through other systems or logical partitions
– This option enables you to send problem information to your service
provider through a pass-through system. This pass-through system can
be another HMC or a logical partition on your server that supports the
Layer 2 Tunneling Protocol (L2TP).
– Currently, only logical partitions with the V5R3 level of I5/OS can support
L2TP, so are the only logical partitions that can be used as pass-through
systems
– You may want to select this option if the following are true:
•
