1 HMC The New Console on the Block John Still Objectives Console History Introducing the Hardware Management Console (HMC) Planning for HMC and i5 Guided Setup Wizard HMC Management Remote Access System Manager Security 2

2 Console History System 38 console built into the system unit 3 Console History Twinax 5250 console 20 feet from the system unit maximum 4

3 Console History PCs gain momentum 5250 emulation card allows PC to become system console Client access PC console iseries access operations console & Lan console 5 Introducing the HMC First introduced on the pseries A LINUX based PC appliance for eserver power5 Tied to specific PC hardware (xseries) Ships with embedded OS pre-loaded Closed and dedicated (can t install other software on it) Required for configuration & management of logical partitioning, capacity on demand and some maintenance functions 6

4 Introducing the HMC Create and maintain a LPAR environment. Display a virtual console session for each i5/os partition. Display or change control panel settings for each partition. Detect, report, and store changes in hardware conditions. Power managed systems on and off. Act as a service focal point for service representatives to determine an appropriate service strategy and enable service agent to call home to IBM. Activate additional resources on demand. The HMC can be disconnected, but you cannot perform any of the above functions. 7 Introducing the HMC Based on xseries server technology Minimum HMC configuration includes: 1 GB memory, 40 GB disk, DVD-RAM, 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 CR2 (rack) 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 for redundancy C03 (desktop)

5 Introducing the HMC - Security HMC Security 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 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 9 Managed System with HMC Managed System i5/os Linux Partition 1 Partition 2 POWER Hypervisor Unassigned Resources Ethernet HMC Non-Volatile RAM Processors Memory I/O Slots LPAR Allocation Tables Service Processor Ethernet 10

6 Service Processor SP (Service Processor) or formerly FSP (Flexible Service Processor) Description: Controls base operations of the i5 system. It is powered up immediately when power is supplied. Defaults as DHCP client. Defaults if no address or range assigned within one minute: and Managed System can operate in the absence of the HMC. LPAR configuration resides in HMC and NVRAM. Maintenance PTFs required (via HMC or i5 OS Partition) 11 Typical Topology 12

7 Why the HMC? Already on the pseries why not the iseries Virtualization Why should operating systems have to worry about hardware A place to host advanced platform management applications regardless of what OS is loaded The ability to configure a server before the OS is loaded Provide virtual consoles (i5, AIX, LINUX) A common delivery vehicle IBM can deliver more functions, more quickly 13 Why the HMC? On an 8XX system your Primary Partition cost: At least.25 Processing Units recommended At least 1 DASD bay or sub bay At least 2 Disk drives At least 512 MB memory At least 1 IOP and 1 Disk IOA and 1 console IOA WAS a single point of failure P0 P1 P2 14

8 eserver Hardware Information Center On the internet Preferred On CD with your shipment Preloaded on the HMC For use once the initial setup and cabling steps have been completed, using either of the other two sources! 15 eserver Hardware Information Center 16

9 eserver Hardware Information Center Extensive Planning and How To documentation For the HMC, make sure you review these sections: Planning for the Hardware Management Console (HMC) Gathering required configuration settings HMC configuration checklist Going through these planning steps will make for a much smoother HMC installation it could save you hours! 17 HMC & Managed System LAN Topology HMC must connect to SP on Managed System Private Network or Open Network (or both) Separate connection to AIX or LINUX for DLPAR To Partitions Internal PCI Modem Network Ethernet Service Network Service Processor HMC Private LAN Service Processor 18

10 Remote Access to the HMC Limit 5 remote users Secure Shell (SSH) Client 4 SSH Access to HMC Commands Remotely Needs to be enabled from the HMC 3 WebSM Access through Windows/Linux/AIX Network ASMI HMC 2 Partition remote virtual terminal aka console via TN Alternate (remote) HMC Additional ethernet requirements When running AIX ( AIX 5L 5.3 or higher ) or Linux partitions on an I5 server, the DLPAR ( dynamic movement of resources ) function for those partitions also requires an external LAN connection to the AIX or Linux partition. This second connection is not required for DLPAR in an I5/OS partition. To dynamically move resources in an AIX or Linux partition, the HMC must also be able to communicate to those partitions over a second LAN connection. The rack-mounted 7310-CR2 HMC has two ethernet ports built in. The first port connects to the HMC1 port on the server and the second port can be used to connect to the AIX or Linux partitions via a lan adapter in the partition or via virtual ethernet if the virtual ethernet can access the HMC over an external connection. The deskside 7310-CO3 requires a feature ethernet adapter because it has only one built-in ethernet port. This is now added by the configurator. Don t remove as it can t be MES d. 20

11 HMC Setup options Private Network port 1 (eth0) HMC = DHCP server (Managed Systems= DHCP client) Direct attach Single Managed System Attached through hub HMC (can add a 2 nd HMC) 1 or more Managed Systems (up to 16) Both i5 & HMC 4.2 Port 1 & 2 identical 21 HMC Setup options Private Network Port 1 Redundant HMC: Synchronized with Primary HMC FSP is DHCP Client (default) FSP is DHCP Client (default) STRONG Suggestion : Connect the first HMC as a LOCAL HMC! 22

12 HMC Network options Open Network port 2 (eth1) Connect to managed systems through network To Local HMC Local HMC Port-a = DHCP server Port-b = DHCP client Remote HMC Port-a/b = DHCP client Direct to Managed System Port-a/b = DHCP client Note: The two ports on the HMC and the Managed System are equivalent Network 23 Rear View of HMC * You must set the voltage selector to the correct position for 115V. Default is 220V. 24

14 Configuring the SP Connect AC Power As soon as AC power is applied, SP begins booting up. The control panel may show both C1xx and D1xx reference codes during SP Boot Note: power light flashes when system is powered off SP is now active powered off state 27 Service Processor Ports Default IP addresses for HMC Port on Service Processor (if not served address) HMC1 = HMC2 = May 12, 2004!) ======== HMC Port 1 ======== HMC Port 2 Model 520 Model 570 (Rack Mounted) 28

15 Change Service Processor IP Address in ASMI Service Processor communication configuration can be viewed and changed through ASMI Connect cable from PC to SP HMC port. Change IP addy on PC to same network segment. Power on SP (no HMC connected) for HMC1 for HMC2 You will see Managed Server (Service Processor) Sign in: admin/admin ORgeneral/general Case sensitive 29 ASMI Admin Password Change the password if this is the first time in. DO NOT LOSE IT! If you do, call IBM Support, who will manufacture a password that is valid for one day Or keep guessing! 30

16 Change Service Processor IP Address in ASMI If you forget the IP address you changed to in ASMI, follow these reset instructions: 31 ASMI Important! Change the date and time systems have been shipping with a date of 1970? The firmware update policy defaults to the HMC recommend changing this to an i5 OS partition that is designated as a Service Partition 32
