Upgrading the machine code on an HMC from Version 6 to Version 7
Learn how to upgrade the machine code on an HMC from Version 6 to Version 7 while maintaining your HMC configuration data.
Perform Steps 1 through 9 to upgrade machine code on an HMC from Version 6 to Version
7.
Important: You must be at a minimum of HMC machine
code Version 6 Release 1.2 to upgrade to Version 7 Release 3.1.0.
Step 1. Obtain the upgrade
You can order the HMC machine code upgrade through the Fix Central website, by contacting service and support, or by downloading it to an FTP server.
Note: If you do not have access to the Internet,
contact service and support to order the upgrade on DVD.
- From a computer or server that has an Internet connection, go to the Fix Central website at http://www.ibm.com/support/fixcentral/.
- From the Product Group list, select Power System Management Consoles.
- From the Product list, select Power Hardware Management Console.
- From the Select from Power Hardware Management Console, select the HMC version and click Continue.
- Locate the Recovery CD download and ordering section.
- Follow the on-screen prompts to submit your order.
- After you receive the upgrade, continue with Step 2. Back up critical console information.
Step 2. Back up critical console information
Back up critical console information before installing a
new version of HMC software
so that previous levels can be restored in the event of a problem
while upgrading the software. Do not use this critical console data
after a successful upgrade to a new version of the HMC software.
Note: If
you choose to back up the console data to removable media (that is,
diskette or DVD), you will need to have a diskette or DVD available.
Step 3. Record the current HMC configuration information
Before you upgrade to a new version of HMC software, as a
precautionary measure, record HMC configuration information.
To record HMC configuration information, follow these steps:
Step 4. Record remote command status
- In the navigation area, select HMC Management.
- Select HMC Configuration.
- In the tasks list, click Enable/Disable Remote Command Execution.
- Record whether the Enable remote command execution using the ssh facility check box is selected.
- Click Cancel.
- Continue with Step 5. Save upgrade data.
Step 5. Save upgrade data
You can save the current HMC configuration in a designated
disk partition on the HMC. Only save upgrade data immediately prior
to upgrading your HMC software to a new release. This action allows
you to restore HMC configuration settings after upgrading.
Note: Only
one level of backup data is allowed. Each time you save upgrade data,
the previous level of data is overwritten.
Step 6. Upgrade the HMC software from Version 6 to Version 7
To upgrade the HMC software, do the following:
