Symptoms

After Mammoth OL6 upgrade Step 2 reboot there is no /root/BDA_REBOOT_SUCCEEDED file on one or more nodes.  Instead /root/BDA_REBOOT_WARNINGS is generated and the file reports "WARNING: Wrong OS disk s1 partition info".  The problem is due to partition names being incorrectly generated with a name of "primary".

This is similar to the errors found during OL5 upgrade as described in:  After the Step 3 Reboot of a Mammoth Upgrade on OL5 /root/BDA_REBOOT_WARNINGS is Generated with "WARNING: Wrong OS disk s0 partition info : 1 ext3 raid 2 ext3 raid 3 linux-swap 4 ext3 ext3" (Doc ID 2267699.1).

Using an example of an OL6 upgrade from Mammoth V4.5 to V4.8 two different warnings are described one when partition 4 needs fixing and one when partitions 2,3,4 need fixing. However any combination of partitions could need fixing.  

Follow the same steps to identify and resolve a /root/BDA_REBOOT_WARNINGS file generated after Step 2 with "WARNING: Wrong OS disk s1 partition info" but with different output.

1. /root/BDA_REBOOT_WARNINGS could report any combination of partitions being incorrect. Below are two examples one when partition 4 is incorrect and one when partitions 2,3,4 are incorrect.

a) /root/BDA_REBOOT_WARNINGS reports output like below when partition 4 is incorrect:
