Re: SAP Installation on IBM-i with Power HA / DR

Hi Sriram,

 

it is hard to describe remotely how to restore a backup. There are too many "variables" to consider. How "crashed" is the OS? Did you "scratch" the system? Or did you keep the disk configuration and just perform a "slip" install of the operating system? Is the available backup a full system save, or does it consist of multiple pieces?

 

If your backup system needed to be scratched and you had a full system save available, the recovery steps would be:

 

  1. Install Licensed Internal Code and recover disk configuration.
  2. Install the Operating System.
  3. When the system is up, end all subsystems.
  4. Restore all user profiles.
  5. Restore all configuration objects.
  6. Restore all libraries (this does not include the database library R3<sid>DATA, since it is on the iASP and does not need to be restored).
  7. Restore all IFS objects (again, only those on the system ASP, not the ones on the iASP).
  8. Restore authorities.

 

(see also Restoring and Recovering the Entire System Including the SAP System - SAP Database Guide: IBM DB2 for i - SAP Library).

 

You may want to consider asking an experienced IBM i expert for some support.

 

Kind regards,

Christian Bartels.
