Hardware Management Console

Before upgrading your machine to HMC 3.3.x, please read the Upgrade prerequisites for special instructions for certain types of upgrades.

Partition and profile information is stored in the Managed System. We suggest that the upgrade to HMC V3 R3.x and updates to the managed system's firmware should not occur simultaneously, to minimize the chance of losing partition data.

Run the "Backup Critical Console Data Task" before upgrading. Save the data to the DVD. This operation allows you to restore your HMC to the state that is was before the update occurred. You can then recover the HMC to the last known state, if the update encounters a problem.

If you have to recover, reinstall the HMC with the HMC recovery CD that you last used to install the HMC. When used in conjunction with the backup that you saved to the DVD, the HMC will be restored to its last known state. Use the instructions found in the HMC Setup and Operations guide.

If you are running the Backup Critical Console Data Task on a Release 3 level of HMC that is less than R3 V2.5 you should first apply the following fix. APAR IY50217 PTF U496327.

The HMC Recovery CD V3 R3.x package is a set of 2 CDs. Follow these steps to upgrade:

1. Run the "Save Upgrade Data task" to save the HMC's current configuration files. Select the option to save to disk.
   Note:
   The save upgrade data task should be run immediately before reboot of the HMC with the recovery CD. If the HMC reboots and does not go to the install menu of the recovery CD, you should rerun the save upgrade task.
   
2. Insert the Volume 1 of 2 Recovery CD into the CD drive, and then reboot the HMC.
3. Use install options F1, and then F1 to do upgrade install.
   After CD 1 installs you will be prompted to install CD #2.
4. Insert the Volume 2 of 2 CD into the CD drive and press enter.
   The HMC will reboot, and then install volume 2.
5. When volume 2 ejects, select option 2, and then press enter to reboot the HMC.
6. After you determine the upgrade was successful, you should run the Backup Critical Console Data task, to protect the customized data of the current V3 R3.x HMC image from a possible disk failure. After the Backup Critical Console Data task is completed on this new HMC version, use the HMC V3 R3.x Recovery CD's to recover your HMC.

Before upgrading the HMC 3.2.6 to HMC version 3.3.5 or greater, you must execute the following steps immediately before running the Save Upgrade Data task. Failure to follow these steps may result in the xserver for on the console to not launch.

1. On the HMC console, go to the virtual console window using the <ctrl><alt><F1> key sequence.
2. Log in as the hscroot user.
3. Log in as the root user. command: su - , enter root password when prompted.
4. Issue the following command:
   rm /opt/hsc/data/hmcConfigured
5. Verify the file was removed by entering the following command:
   ls /opt/hsc/data/hmcConfigured
   The command output should return: "No such file or directory"
6. Return to the X desktop using the <ctrl><alt><F2> key sequence.
7. Finally, run the Save Upgrade Data Task.

You are now ready to proceed with the upgrade.

After upgrading the HMC 3.2.6 to HMC version 3.3.5 or greater , the root password for the HMC may no longer work . You will not be able to login as the root user from the pe shell.

To correct this problem:

1. Log in to the HMC using the hscroot user id.
2. Right-click on the desktop, and then select Terminals and rshterm to open an rshterm.
3. Issue the following command:
   chhmcusr -u root -t passwd -v <the new password>

1. Keyboard mapping is not saved for this update. At startup you will be prompted to select the keyboard type after the reboot of the second CD.
2. The Switch Group Configuration information will not be restored after this update. Switch groups are normally only used in High Performance Switch (HPS) clusters.
   To save your switch group configuration:
   1. Enable ssh on the HMC.
   2. From a remote server, use the following command to save the file:
      scp hmc_user_id@hmc_hostname:/opt/hsc/data/HmcNetConfig local_dir/HmcNetConfig
      (local_dir is the directory on your local system).
      Use the same hmc_user_id that was used to originally create the switch group, if you encounter a permissions problem.
   After the upgrade
   1. Enable ssh on the HMC.
   2. From a remote server, use the following command to save the file
      scp local_dir/HmcNetConfig hmc_user_id@hmc_hostname:/opt/hsc/data/HmcNetConfig

1. The System Manager Security settings are not preserved during the 'Backup/Restore' process. This sets up a secure connection when using the WeBSM remote clients. This setting will need to be reconfigured. Be sure to record the setting before upgrading to HMV code V3 R3.x.
2. WebSM Console and user preferences are not preserved during the 'Backup/Restore' process. The Fonts and style settings will revert to defaults. Be sure to record the setting before upgrading to HMV code V3 R3.x.

Before upgrading an HMC Model 6792-LPU to HMC version 3.3.5 or greater, you must verify that the USB setting in the HMC BIOS is enabled. To access the HMC BIOS, reboot the HMC and press F1 at the initial screen. The USB setting is in the Advanced option section.
