We have 12.2.0.1 oracle RAC on Oracle Linux Server release 6.8. We are facing a compatibility issue with OEL kernel version & power path version on our Oracle RAC nodes.
[oracle@prddb1 ~]$ uname -a
xxxx 4.1.12-37.4.1.el6uek.x86_64 #2 SMP Tue May 17 07:23:38 PDT 2016 x86_64 x86_64 x86_64 GNU/Linux
Kernel version: 4.1.12-37.4.1.el6uek.x86_64
Powerpath version: EMC powermt for PowerPath (c) Version 6.1 P 01 (build 3)
We have tried both powerpath upgrade & kernel upgade. But it didn’t fix.
steps we perform :-
1. Upgraded the PowerPath version to 6.4
getting below error while starting after upgrade:
[root@prddb2 log]# /etc/init.d/PowerPath start
Starting PowerPath:
Error: This version of PowerPath will work only on retpoline enabled kernels.
Failed
2. Booted with the Kernel 2.6.32-754.el6 (which is mentioned in the compatibility matrix of powerpath 6.4)
getting below error while starting after upgrade:
[root@prddb2 ~]# /etc/init.d/PowerPath start
Starting PowerPath: This package requires a Oracle Platform.
We have reverted back to Kernel version: 4.1.12-37.4.1.el6uek.x86_64 and Powerpath version 6.1 P 01 (build 3).
* Raised SR with EMC, they say PowerPath supports only retpoline kernel & ours is not retpoline kernel. Kindly advise on best possible way to use Power Path.
Thanks a lot
