PowerHA Tools for IBM i 5.2 is now available for all customers current on maintenance. It has all the features and fixes from prior releases, and adds the following:

Upgrading to 5.2 is only recommended from version 4.6 or 5.1 - upgrading from any other release will require manually re-creating all WRKCSE, WRKCSEDTA and WRKCSECRDL entries. Use the following command to display the version and build date:

DSPDTAARA DTAARA(QZRDHASM/BUILD)

All the controllers and source LPARs in a cluster must be at the same version (i.e. 5.2). We strongly recommend that they also all be at the same build date. The version and build date is stored in data area QZRDHASM/BUILD.

The 5.2 controllers will support non-cluster source LPARs running at 4.6, 5.1 or 5.2, which facilitates upgrading source LPARs in stages.

Use WRKCSE opt 2 to update any FSFC environments using FlashCopy from FlashSystem MMIR targets. Add the source device IP and consistency group. This will enable the toolkit to pause replication before a FlashCopy to prevent torn pages.

1. Ensure the controllers are at 4.6 or 5.1 before proceeding.
2. Ensure no STRFSFLASH or STRFLASH or SWCSE commands are in process.
3. End the toolkit subsystem:

   
   ENDSBS QZRDFSR *IMMED

4. Generate a text file with all of the WRKCSE / WRKCSEDTA information:

   
   QZRDHASM/DMPINF ENV(*ALL) EXTDLOGS(*NO)

5. Save the DDD information:

   
   MKDIR '/tmp/ddd46backups'
   QZRDHASM/SAVDDD PATH('/tmp/ddd46backups')

6. On each controller, issue the restore command:

   
   RSTLIB SAVLIB(QZRDHASM) DEV(*SAVF) SAVF(QGPL/QZRDHASM52) MBROPT(*ALL) ALWOBJDIF(*COMPATIBLE) OMITOBJ((QZRDHASM/*ALL *DTAQ))

7. Update to the most recent Secure Java JAR file.
   Download it from here: https://sourceforge.net/projects/jsch/files/jsch.jar/0.1.55/jsch-0.1.55.jar/download
   Place it on all controllers in /QIBM/Qzrdhasm/ssh/
   Then update the links if a new jar file is downloaded:

   RMVLNK OBJLNK('/QIBM/Qzrdhasm/ssh/jsch.jar') 
   ADDLNK NEWLNK('/QIBM/Qzrdhasm/ssh/jsch.jar') OBJ('/QIBM/Qzrdhasm/ssh/jsch-0.1.55.jar') 

8. On each controlling partition issue the setup command:

   
   SETUPFSFC NODEROLE(*CTL) MIGRATE(*YES)
