Oracle Support Suggestion:-
==========================

The issue look to be caused by below bug, which enforces hard DNS check and expects results from DNS to exactly match the FQDN.

Bug 26002739 – SOLARIS:ROOTUPGRADE.SH FAILING DUE HARD DNS CHECK

Please attempt the below workaround and provide feedback:

1) Take backup of “GRID_HOME/bincluutil” & “GRID_HOME/crs/sbs/cluutil.sbs” “file

2) Edit both files and make following change ( under SunOS block )

Comment :: JRE_OPTIONS=”-d64 -Dsun.net.spi.nameservice.provider.1=dns,sun -Xms256m -Xmx512m”

Add new line right below commented text :: JRE_OPTIONS=”-d64 -Xms256m -Xmx512m”

===== updated SunOS block should look like ::

SunOS)
LD_LIBRARY_PATH_64=$ORACLE_HOME/lib:$ORACLE_HOME/srvm/lib:$LD_LIBRARY_PATH_64
export LD_LIBRARY_PATH_64
LD_LIBRARY_PATH=$ORACLE_HOME/lib:$ORACLE_HOME/srvm/lib:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH
# JRE_OPTIONS=”-d64 -Dsun.net.spi.nameservice.provider.1=dns,sun -Xms256m -Xmx512m”
JRE_OPTIONS=”-d64 -Xms256m -Xmx512m”
;;

======

3) Then execute root.sh from 12.2 GI home and share result.

After the workaround root.sh was successful.

See the below reference note :-

Please try the workaround given in the bug or use the patch p26002739_122010_SOLARIS64.zip

Ref: root.sh or rootupgrade.sh Fails With CLSRSC-175 Error For Grid Iinfrastructure 12.2.0.1 on Solaris ( Doc ID 2285577.1 )
