ProtecTIER Upgrade Path Explanation

Technote (troubleshooting)


Problem(Abstract)

Understanding ProtecTIER upgrades including versions that are based on a new Redhat Update and versions that only involve new ProtecTIER code.

Symptom

Understanding the Upgrade path for any given system depends on the Current level and the planned level of ProtecTIER code.


Cause

Some upgrades require an Update to Redhat 5

Environment

All ProtecTIER solution

Diagnosing the problem

If you are planning an upgrade, this guide should assist you in preparing for each of the steps

Resolving the problem





The above Figure shows which range of ProtecTIER is running on each of three different Redhat Updates. Since Redhat distributions require special licensing from Redhat, IBM customers can get the required Redhat updates included with their software maintenance agreement . In order to track the distribution, IBM is required to provide entitlement information for each copy provided. This is done by contacting the IBM sales group or business partner, and requesting an update. Since ProtecTIER comes packaged with the Redhat at each of the levels, simply requesting ProtecTIER 2.4 or ProtecTIER 3.1.8 will also include the Redhat Update in the provided media.

All other ProtecTIER upgrades do not require special entitlement and therefore are available from the IBM download Website (Fix Central) . In all cases that do not change to a newer Redhat Update, the ProtecTIER upgrade can be applied directly. All levels that change Redhat update level must be performed in a staged manner.

Software orders can be obtained by requesting the correct product ID for your type of solution.

Redhat Update 4 :
Feature code 5829 against PID 5639-XXB (Enterprise Edition)
Feature code 5809 against PID 5639-XXP (Appliance Edition)

Redhat Update 6:
ProtecTIER Enterprise Edition (TS7650G), feature code 5806 under PID 5639-PTA
ProtecTIER Appliance Edition (TS7650 AP1), feature code 5806 under PID 5639-PTB
ProtecTIER Entry Edition (TS7610 SMB medium capacity), feature code 5816 under PID 5639-PTC
ProtecTIER Entry Edition (TS7610 SMB small capacity), feature code 5806 under PID 5639-PTC

If a Redhat update is required, once the media is received, the Redhat operating system can be upgraded from the DVD. After the Redhat update is complete, ProtecTIER can be upgraded directly to any level within that matching range.

Upgrade Note: Beginning August, 2012, IBM is shipping two Maintenance and Recovery Disk sets - the 3.2 version and the 3.1.11 version - with the feature codes listed above.
- Use the 3.1.11 Maintenance and Recovery disk to upgrade to either 3.2 or 3.1.8+,
- Use the 3.2 Maintenance and Recovery Disk to install ProtecTIER 3.2 or higher.

If you wish to run 3.1.11 (or another higher 3.1.x level, such as 3.1.12) and did not receive a 3.1.11 Maintenance and Recovery Disk, please call IBM support and reference this technote.

(Background: While ProtecTIER 3.2 uses the same Redhat update 6 as 3.1.8+, the Maintenance and Recovery Disk contains different Kernel files that are not recognized by ProtecTIER 3.1.8+.)

Note: Installs differ from upgrades since the assumption is that the local hard disk has been formatted and the Redhat has been installed on the disk. This means that there are no ProtecTIER configuration files to be upgraded, and therefore have special considerations that are explained in the above matrix.

Summary:
A simple way to think of this dependancy is that whenever a Red Hat Level changes (from 2, 4 or 6) it requires Redhat to be updated first. At that point, ProtecTIER can upgrade directly to any level just like any other ProtecTIER patch or upgrade. All Levels of ProtecTIER work on only 1 matching level of Redhat update (5.2, 5.4 or 5.6)
