Overview of upgrading a TS7650G (Gateway) server to ProtecTIER V3.4.3

This document provides instructions for upgrading servers that are running any ProtecTIER version 3.4.x to the latest available of ProtecTIER 3.4 branch. This document also provides instructions for upgrading servers that are running ProtecIER version 3.3.x to the latest available version of ProtecTIER 3.4 branch.

The following is an overview of the steps that might be required to upgrade the ProtecTIER software. Depending on the current status of the ProtecTIER server, you may not need to do all these steps.

Detaching the TSSC microcode when replacing 3958 DD4 or 3958 DD5 servers with a 3958 DD6 server. See Detaching the TSSC.
Configuring Electronic customer care (ECC) for 3958 DD6 servers. See Call Home through ECC.
Reimaging the TSSC microcode, if needed. See Reimaging the TSSC microcode for the TS7650G (Gateway).
Upgrading the version of ProtecTIER® Manager to version 3.4, on theProtecTIER Manager workstation. See Upgrading ProtecTIER Manager on the TS7650G (Gateway).
Upgrading to Red Hat Linux version 5.11 and ProtecTIER 3.4.x if the server is at ProtecTIER version 3.3.x. SeeUpgrading Red Hat Linux and ProtecTIER version 3.4.x for servers at version 3.3.x.
Upgrading ProtecTIER to 3.3.x if the server is at version 3.1.8, or higher. See Upgrading the ProtecTIER software to 3.3.x from version 3.1.8 or higher using ProtecTIER Manager.
Downloading and installing the most current patch update version of ProtecTIER on servers currently running ProtecTIER 3.4.x. See Applying fix packs for ProtecTIER systems already at version 3.4.
For instructions on upgrading ProtecTIER servers running a ProtecTIER version lower than 3.1.8, please refer to a previous version of the IBM TS7650 with ProtecTIER Software Upgrade Guide.

These instructions involve stopping services several times. Read the instructions carefully so you start and stop the services at the appropriate time in the process. Failure to stop the services correctly can result in unnecessary fencing.

If the code upgrade fails, you are directed to go to Recovering from a failed upgrade. The topic provides information to troubleshooting your problem and what action to take to resolve the problem.

This document does not address the following topics:

Installation of new 3958 DD6 hardware. Refer to the IBM® TS7650G ProtecTIER Deduplication Gateway Installation Roadmap Guide, GA32-0921
Configuration and setup of any recommended hardware components that were not included in the purchase of the TS7650G. Components such as the disk controller and disk expansion modules must be configured and operational before installation of the TS7650G.
Hardware or software troubleshooting. Refer to the IBM Problem Determination and Service Guide for the TS7650G ProtecTIER Deduplication Gateway, GA32-0923.
Daily use and ongoing maintenance of the ProtecTIER, ProtecTIER Manager, and ProtecTIER Replication Manager, software. Refer to the IBM ProtecTIER User's Guide for VTL Systems, GA32-0922.

Notes:

Upgrading to version 3.4 ProtecTIER software is supported on the existing 3958 DD4 and 3958 DD5 servers.
Existing 3958 DD3 servers need to be replaced in order to run ProtecTIER V3.4. 3958 DD3 servers support a temporary upgrade for server replacement only. Refer to the iRPQ 8B3667 Server Replacement 3958 DD3 with 3958 DD6 PN 00VJ479, EC M13702A for information on replacing 3958 DD3 servers.

Important: A USB keyboard and graphics-capable monitor are required to complete the upgrade. These items are not provided in the ship group; they must be provided by the customer.
