Updating the HMC software level from a HMC Recovery CD set
If you have received the HMC Recovery CD set, then you can upgrade your HMC release
using these CDs.
When we update the HMC with the Recovery CD set, we are in fact replacing all the HMC
data on the HMCs disk. To ensure that we keep all of our user data, such as partition/profile
data, user profiles, user preferences, network configuration, etc., we must perform the Save
Upgrade Data task on the HMC immediately before the HMC update. The Save Upgrade
Data task is used to save the current HMC configuration to a special disk partition on the
HMC. This data is then reloaded automatically during the update process.
The next steps show how to update the HMC with the Recovery CD set:
1. Save the current HMC configuration by following these steps:
a. In the HMC Navigation area, click Licensed Internal Code Maintenance.
b. Then select HMC Code Update.
c. In the right-hand window click Save Upgrade Data.
d. An information window opens (Figure 14-12) and prompts you to select the media type
for the backup.
Figure 14-12 Save Upgrade Data media selection
Select the Hard drive radio button and click Continue.
Important: The HMC Backup Critical Console Data task is not the same as the Save
Upgrade Data task.
The Save Upgrade Data task is only used during a HMC software update from the
Recovery CD set.
The Backup Critical Console Data task is used to save the HMC configuration to removal
media or a remote system. This backup CAN NOT be used during the HMC update.
However, we recommend that you take a Critical Console Data backup before doing any
software updates on the HMC, in case the update process fails.
Important: The Save Upgrade Data to DVD media can only be used by IBM service
personnel.
