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 2004 IBM Corporation PAGE 9
When is an HMC Required on i 5 System? • Systems with multiple Partitions (LPAR) • Systems with Capacity on Demand • Systems with redundant service processors • Systems yet to be announced (High-end) © 2004 IBM Corporation PAGE 10
What is an HMC • Based on x. Series server technology, built upon p. Series HMC device • Runs an IBM-provided GUI console application – Not to be used with customer applications 7310 -C 03 (desktop) – Helps ensure a more stable console environment • Required – To create/modify partition – not to run it – For Capacity on Demand functions • 5250 interface for optional i 5/OS console is provided • Remote console by other workstations through HMC – 5250 interface via Telnet 5250 client 7310 -CR 2 (rack) – Windows/Linux/AIX Client interface for HMC interface • At August 2004 i. Series GA, one HMC can support a maximum of 64 partitions across up to 16 servers. http: //www-1. ibm. com/servers/eserver/iseries/literature/index. html © 2004 IBM Corporation PAGE 11
HMC – More Details • Based on x. Series server technology – Minimum HMC configuration includes: 1 GB memory, 40 GB disk, DVDRAM, 10/1000 Mbps Ethernet port, diskette drive, etc. – Selectable options for HMC’s display, keyboard, etc. (ordered separately) – HMC connects to POWER 5 service processor, which has two dedicated HMC ports. The ports are Ethernet ports. (Different from the two generic 10/1000 Mbps Ethernet LANs. ) • Standard HMC maintenance support is CRU. Suggest upgrading support to IBM On-Site Repair to be more consistent with POWER 5 server’s support agreement. • HMC not used on earlier i. Series servers • Non-HMC i 5/OS consoles are still supported • High availability suggestion: attached two redundant HMCs to critical Power 5 servers. * Product preview © 2004 IBM Corporation PAGE 12
Hardware Management Console (HMC) 7310 -CR 2 (rack) 7310 -C 03 (desktop) • HMC is dedicated to console functions (installing 3 rd applications is not allowed) • Required on POWER 5 servers to create/change partitions or to use Capacity on Demand • Not required to operate the partition • Saves the cost of typical primary partition © 2004 IBM Corporation PAGE 13
Hardware Management Console (HMC) • Single console for POWER 5 servers – Pre-installed embedded OS – Desktop or rack mount – Supports local consoles, including 5250 console – Web-based System Manager enables local or remote management for HMC control and status • Required on POWER 5 servers to create/change partitions (LPAR) or to use Capacity on Demand – Replaces primary partition and improves system resiliency – Can co-exist with 5250 twinax, Operations Console direct attach, Operations Console for the LAN – Not required to operate the partition © 2004 IBM Corporation PAGE 14
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 (Web. SM 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 5 L – 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 © 2004 IBM Corporation PAGE 15
Advanced System Management User Interface • Service Processor Menus (SP is part of the Power 5 server) – Accessed by Web browser – Secure (HTTPS) access – Password authentication – Basic server operations § No partition functions • Remotely manage some system functions (VPD, logs, dumps, etc. ) • Many of these functions are also on the HMC – A few less common ones only in ASMI – Browser interface can be launched on the HMC © 2004 IBM Corporation PAGE 16
Web-based System Manager Remote Client • Two remote clients install options available: – 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 this remote client on your PC workstation • The remote 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 • Uses SSL security • 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: e. Server Information Center. . © 2004 IBM Corporation PAGE 17
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 Web. SM or SSH access to a single interface, or none © 2004 IBM Corporation PAGE 18

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 © 2004 IBM Corporation PAGE 20

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 I 5/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. © 2004 IBM Corporation PAGE 31
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 (L 2 TP). – Currently, only logical partitions with the V 5 R 3 level of I 5/OS can support L 2 TP, so they are the only logical partitions that can be used as passthrough systems. – You may want to select this option if the following are true: • • © 2004 IBM Corporation PAGE 32 Your HMC does not have access to a high-speed Internet connection You have an I 5/OS logical partition with high-speed Internet connections, running V 5 R 3
Customizing Connectivity Settings © 2004 IBM Corporation PAGE 33
Electronic connections to IBM • LIC Fix Strategy— The HMC connection type that you select here also dictates how you will install your server LIC fixes. – For example, if you choose to connect to your service provider through your HMC, you will install server LIC fixes through your HMC. • For I 5/OS logical partitions, use the normal I 5/OS PTF install functions on your service partition for installing fixes, rather than using the HMC. © 2004 IBM Corporation PAGE 34
LPAR, HMC, Service Partition • Existing i. Series LPAR environments (non-POWER 5) already have procedures for handling service and support functions among partitions – Reporting all hardware and software problems – Receiving fixes (PTFs), distributing and applying fixes to the affected partitions – Other services • On POWER 5 HMC is used for primary hardware service and support • Service tools run in each logical partition and work with the (HMC) as part of the total service environment • i. Series Consideration: – One (any) active logical partition on your IBM e. Server i 5 system be designated as a service partition – Consider the partition running applications or a small configuration partition only active for operating service functions – Provides traditional service functions such as reporting software problems, receiving operating system-based fixes, . . or “backup” your HMC. – Can complement HMC service and support functions © 2004 IBM Corporation PAGE 35
Service/Problem Flows • Service information and problems flow from each logical partition to the service provider using a VPN connection, as follows: – Linux logical partition > HMC > OS/400 service partition > Service and support – AIX logical partition > HMC > OS/400 service partition > Service and support – OS/400 logical partition > HMC (for service information) > OS/400 service partition > Service and support – OS/400 logical partition > OS/400 service partition (for problems) > Service and support – OS/400 service partition > Service and support © 2004 IBM Corporation PAGE 36
