Affected Products and Versions
IBM Spectrum Scale V188.8.131.52 thru 184.108.40.206 and V220.127.116.11
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 V18.104.22.168 thru 22.214.171.124, apply 126.96.36.199 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 V188.8.131.52 , 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 184.108.40.206 or had the efix applied, run the following commands:
Verify the reported value of minReleaseLevel is 220.127.116.11 or higher. Note that applying the V4.2 efix will not result in minReleaseLevel being changed.
