HMC code update

You might need to update the HMC code to the latest version. If you are sure you have the latest version of HMC code on both HMC box and on eServer i5, you may skip this section. In case you need to update it, the following instructions show how to upgrade your HMC with the recovery CD media.

1. Take the IP configuration that connects your HMC console with your i/5 box. To do this, in your HMC console click on your server HMC Management → HMC Configuration. Then click on Customize Network Settings task as illustrated in Figure 3-1.

Note: These steps are not required if your eServer i5 HMC and Licensed Internal Code are both post GA2 level. If this is the case, you may skip this section and jump to Section 3.2, “Configuring Linux partition” on page 62.

2. When the Customize Network Setting window appears, click on LAN Adapters tab as illustrated in Figure 3-2. Take ‘eth0’ and click on the Details button. Write down the address netmask and other network configuration and press Cancel button to go back to the HMC main menu.

3. Since we are going to update the HMC code, we need to save the current configuration. Otherwise, we will lose all current settings when we update the HMC code itself. To save the current configuration, expand License Internal Code Maintenance on the navigation area, then select HMC Code Update. On the content area, select Save Upgrade Data as illustrated in Figure 3-3.

Note: This IP address of the Lan adapter “eth0” is the one used for the direct connection between the HMC box and eServer i5 box.

4. Select the Hard drive option as illustrated in Figure 3-4. Then click Continue.

5. When successful operation message shows up as illustrated in Figure 3-5, click OK.

6. Reboot your HMC with the first CD of the recovery CD media to get the screen as illustrated in Figure 3-6.

7. Press F1 to perform an Upgrade. When Figure 3-7 appears, press F1 to continue.

8. When prompted to put CD 2, insert CD 2 and press enter. Repeat this for CD 3. 9. Select finish after the CD 3, then the HMC console will reboot.

10.At the login prompt as illustrated in Figure 3-8, log in with the default userid and password as illustrated below. This will start the wizard.

Login: hscroot Password: abc123

11.On the HMC main menu, click on HMC Management → HMC Users, then choose Manage HMC Users and Access option as illustrated in Figure 3-9.

12.In this menu, change the default password of hscroot. First, highlight the user “hscroot”, then select User→ Modify as illustrated in Figure 3-10.

13.Next, we need to configure IP address for the direct connection. On the HMC main menu and select HMC Management → HMC Configuration. Then click Customize Network Settings task as illustrated in Figure 3-11.

14.For actual IP address, we use the one we collected from step 2 on page 49. Click on LAN Adapters tab, select the eth0 device and click on Details button as illustrated in

Figure 3-12. Fill in the LAN Adapters Details window the appropriate network and IP information to enable the communication between your i/5 box and your HMC console.

15.Once IP configuration on the HMC box is done, we need the IP address on the eServer i5 side and add it as a managed system on HMC. There can be two cases in this step: One is the case you already know the IP address on the i5 side and the other case is you don’t know the IP address and you need to find it first. In either case, on the HMC main menu, choose Server and Partition → Server Management. From the menu bar, select Server Management → Add Managed System(s) as illustrated in Figure 3-13.

a. If you know the IP address, add its IP address and password on the screen shown in Figure 3-14 which is brought to you from the previous step.

b. If you do not know the IP address yet, then you need to find it out first. There are two ways of doing that: One is giving a proper range of the IP addresses and letting HMC find it for you. The other way is using Advanced System Management (ASM). First, to use the range way, click on Find managed systems radio button as illustrated in Figure 3-15 and give the proper range. This can take quite a bit long depending on the range.

c. Another way is to use ASM. This book does not discuss ASM in details. For the information of how to use ASM, refer to IBM eServer Hardware Information Center at:

http://publib.boulder.ibm.com/infocenter/iseries/v1r2s/en_US/index.htm

But briefly, ASM or ASMI (Advanced System Management Interface) is the interface to the service processor that allows you to perform general and administrator level service tasks such as reading service processor error logs, reading vital product data, setting up the service processor, and controlling the system power. The ASMI may also be referred to as the service processor menus. You can access the ASMI through a web browser or the HMC.

From the ASM main menu as illustrated in Figure 3-16, log in with default

d. Choose Network Services → Network Configuration as we shown in Figure 3-17. In our example the ethernet device that is attached with the HMC console is the eth0.

e. Take the IP information and use it to Add Managed System.

16.When you are done with adding managed systems, click on Finish button to confirm that you want to add this system. Now we are restored to the system setup as illustrated in Figure 3-18.

Next step will be updating Licensed Internal Code.
