Affected Products and Versions

IBM Spectrum Scale V4.1.1.0 thru 4.1.1.3 and V4.2.0.0

Remediation/Fixes


The following fixes will need to be applied to all nodes in the cluster regardless of whether they are configured as protocol nodes or not.

For all IBM Spectrum Scale nodes V4.1.1.0 thru 4.1.1.3, apply 4.1.1.4 available at http://www-933.ibm.com/support/fixcentral/swg/selectFixes?parent=Software%2Bdefined%2Bstorage&product=ibm/StorageSoftware/IBM+Spectrum+Scale&release=4.1.1&platform=All&function=all

For all IBM Spectrum Scale nodes V4.2.0.0 , contact IBM Service and request an efix for APARIV79381 and follow the instructions in the associated README.

After all nodes have either been upgraded to 4.1.1.4 or had the efix applied, run the following commands:

 
    • mmchconfig release=LATEST

      mmlsconfig minReleaseLevel


Verify the reported value of minReleaseLevel is 4.1.1.4 or higher. Note that applying the V4.2 efix will not result in minReleaseLevel being changed.
