Document Title
Upgrading the HMC from Version 7.3.x or Version 7.7.x to Version 7.7.7
Document Description
This document provides instructions to upgrade the HMC from Version 7.3.1 or later to Version 7.7.7.
Prerequisites
Important Notes:
o Version 7.7.7 is not supported and cannot be installed on HMC models C03, C04 or CR2.
o If an HMC is used to manage any POWER7 processor based server, the HMC must be a model CR3 or later model rack-mount HMC or C05 or later deskside HMC.
Click here for a complete list of supported combinations of HMC V7 code levels and server firmware levels. Servers below the supported level should be updated after the HMC upgrade is complete.
Confirm machine type/model and serial number are correct
Use one of the methods below to verify that the Machine Type/Model and Serial Number (MTMS) matches the information on the tag on the front of the physical HMC. If they do not match, do not attempt the upgrade. To resolve the problem, contact IBM Hardware at 1-800-426-7378 (800-IBM-SERV), Option 1 for hardware, and request a BIOS flash to correct the MTMS:
| o | On the HMC GUI interface, select Updates in the left-hand navigation panel. Find Model Type and Serial number in the HMC Code Level section of the right-hand panel. |
| o | From a restricted shell command line, type the following command and press Enter: lshmc -v *TM is the machine type/model, and *SE is the serial number. |
Critical special instructions when using redundant Management ConsolesCritical special instructions when using redundant Management Consoles
Note: HMC 7.7.7 does not support dual/redundant management with IBM Systems Director Management Console (SDMC).
When two HMCs manage the same Server, both HMCs must be at the same version. Once the server is connected to a V7R7.6 or V7R7.7 HMC, the partition configuration on the server will be migrated to the latest version. HMCs at V7R7.5 or lower will not be able to understand the server's partition data properly.
If the redundant HMCs are at 7.7.5 or earlier:
To avoid possible corruption of the partition data on the server, the following is recommended in a redundant HMC environment:
o On each HMC, perform a Save Profile Data for each managed system to save an additional copy of partition/profile configurations - complete steps 1-7 of the section below titled Save Profile Data, Save Upgrade Data and Upgrade HMC to 7.7.7.
o Physically disconnect the ethernet cable from HMC #1 to the managed server(s)
o Upgrade HMC #1 to V7.7.7 and install recommended fixes (start with step 8 below since 1-7 were already performed above)
o Physically disconnect the ethernet cable from HMC #2 to the managed server(s)
o Reconnect the ethernet cable from HMC #1 to the managed server(s)
o Confirm HMC #1 connects successfully to managed server(s)
o Upgrade HMC #2 to V7.7.7 and install recommended fixes (start with step 8 below since 1-7 as they were already performed above)
o Reconnect the ethernet cable from HMC #2 to the managed server(s)
o Confirm HMC #2 connects successfully to managed server(s)
If the redundant HMCs are at 7.7.6, continue with upgrade instructions below.
Additional Required Fixes
If the HMC is at 7.3.2 or later, no further preparation is required, and the upgrade to 7.7.7 can proceed as indicated below in theDownload and burn HMC .iso images, obtain HMC media from IBM, or download direct from IBM to HMC section.
For HMC version 7.3.1, ensure the following prerequisite is met before the upgrade:
Note: MH01135 must be applied before saving the upgrade data.
| 1. | To enable the ability to upgrade to HMC 7.7.7.0, apply PTF MH01135 to HMC 7.3.1.0 . To apply MH01135, refer to Rochester Support Center knowledgebase document 509738064, HMC Upgrade enablement PTF for 7.3.1 To link to document 509738064 immediately, click here  . |
| 2. | Use the instructions below to upgrade to HMC 7.7.7.0 using of the HMC V7R770 Recovery media. |
Remote SSH Connectivity
When upgrading to HMC 7.7.7, "Remote Command Execution" (SSH) may be disabled. Prior to upgrading, ensure that local HMC access, or remote web browser access, is available to re-enable remote command execution after the upgrade should that be necessary. Instructions for enabling are provided in Rochester Support Center knowledgebase document 527678874 Configuring the Version 7 HMC to Accept SSH Connections and Remote Commands.

Readme file for HMC V7 R7.7.0 Recovery Media can be found at the following URL:
http://www-933.ibm.com/support/fixcentral/firmware/readme?fixid=MH01343
If the HMC has not been restarted recently, you should restart before you begin the upgrade.
Download and burn HMC .iso images, obtain HMC media from IBM, or download direct from IBM to HMC
Choose one of the following:
| To obtain HMC 7.7.7 .iso images, do the following: Step 1: Download the HMC Version 7.7.7.0 Recovery DVDs: HMC_Recovery_V7R770_1.iso andHMC_Recovery_V7R770_2.iso. Step 2: Burn the Recovery images to DVD-R media. Save Profile Data, Save Upgrade Data and Upgrade HMC to 7.7.7 (from Recovery Media) Perform a Save Profile Data for each managed system to save an additional copy of partition/profile configurations. Then, a Save Upgrade Data task must first be done to preserve information on the HMC before performing the upgrade. You must upgrade immediately after the Save Upgrade Data task. If you restart the HMC again without doing the upgrade, you must log in and run the Save Upgrade Data task again before performing the upgrade. Do the following at the HMC interface to upgrade the HMC by means of the Recovery DVDs. Note: If you have redundant HMCs and have already completed steps 1-7, skip to step 8. Otherwise, start with step 1

Install the required fixes for 7.7.7
Critical fixes for 7.7.7 must be installed. Follow the instructions to get the corrective service updates applied by referring to Rochester Support Center knowledgebase document 661704005, Update(s) for HMC 7.7.7. To link to document 661704005 immediately, click here
