Affected Products and Versions

IBM Spectrum Scale V4.1.1 thru 4.1.1.3 and V4.2

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 IBM Spectrum Scale 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 IBM Spectrum Scale V4.2, apply 4.2.0.1 available at
http://www-933.ibm.com/support/fixcentral/swg/selectFixes?parent=Software%2Bdefined%2Bstorage&product=ibm/StorageSoftware/IBM+Spectrum+Scale&release=All&platform=All&function=all

After all nodes have either been upgraded to 4.1.1.4 or 4.2.0.1, run the following commands:

• mmchconfig release=LATEST

mmlsconfig minReleaseLevel

Verify the reported value of minReleaseLevel is 4.1.1.4 or higher. The value should be 4.2.0.1 if all nodes in the cluster are running with version 4.2.0.1 .
