Upgrading RAC from 12.1.0.1 to 12.1.0.2 - Grid Infrastructure

This post gives the highlights of a grid infrastructure upgrade from 12.1.0.1 to 12.1.0.2. It is not a step by step guide to upgrade but to shows things to look out for during the upgrade. For comprehensive information refer oracle documentation. The system to be upgraded is a 2 node cluster running on RHEL6(x86-64) with role separation and uses GNS.
Running the cluster verification (cluvfy) shows few failed pre-reqs which are new to 12.1.0.2 or known issues which could be ignored. First is the panic_on_oops kernel parameter.
Check: Kernel parameter for "panic_on_oops"
  Node Name         Current       Configured    Required      Status        Comment
  ----------------  ------------  ------------  ------------  ------------  ------------
  rhel12c1          1             unknown       1             failed (ignorable)  Configured value incorrect.
  rhel12c2          1             unknown       1             failed (ignorable)  Configured value incorrect.

PRVG-1206 : Check cannot be performed for configured value of kernel parameter "panic_on_oops" on node "rhel12c1"
PRVG-1206 : Check cannot be performed for configured value of kernel parameter "panic_on_oops" on node "rhel12c2"
By default this is set to 1 so this could be safely ignored or panic_on_oops kernel parameter could be added to sysctl.conf. For more information refer PRVG-1206 : Check cannot be performed for configured value of kernel parameter "panic_on_oops" on node "racnode1" (Doc ID 1921982.1)
Second is with regard to DNS response times.
Checking DNS response time for an unreachable node
  Node Name                             Status
  ------------------------------------  ------------------------
  rhel12c1                              failed
  rhel12c2                              failed
PRVF-5636 : The DNS response time for an unreachable node exceeded "15000" ms on following nodes: rhel12c1,rhel12c2
Refer an earlier post regarding PRVF-5636/PRVF-5637.
Also connected to DNS, make sure that public host names are resolved through the DNS. This could be done by adding entries to forward and reverse name look up files.
add host resolving to DNS
cat /var/named/rev.domain.net.zone
93     IN PTR  rhel12c1.domain.net.
94     IN PTR  rhel12c2.domain.net.

 cat /var/named/domain.net.zone
rhel12c1   A         192.168.0.93
rhel12c2   A         192.168.0.94
The grid infrastructure management repository is no longer optional in 12.1.0.2. This by default will get installed in the same disk group where OCR and vote disks are as such this disk group need to be expanded.
ASMCMD> lsdg
State    Type    Rebal  Sector  Block       AU  Total_MB  Free_MB    Voting_files  Name
MOUNTED  EXTERN  N         512   4096  1048576      1098      801     Y           CLUSTERDG/
MOUNTED  EXTERN  N         512   4096  1048576     10236     8073     N            DATA/
MOUNTED  EXTERN  N         512   4096  1048576     10236     8687     N            FRA/
Size of the disk group depends on the number of nodes and repository data retention time, which at the time of upgrade has no control over. If there's not enough space on the disk group then upgrade will not proceed and required amount of space will be given in the error details.
Add more disks to the disk group containing clusterware files or move the clusterware files and ASM password file to a disk group with sufficiently large. Later, if needed this CHM repository database could be moved to a different disk group, refer 1589394.1
Since the CHM creates a database the dbca folder inside $ORACLE_BASE/cfgtoollogs needs write permission for oinstall group as this CHM related database is created as grid user. Without this write permission the CHM repository database creation will fail.
[root@rhel12c1 cfgtoollogs]# ls -l
drwxr-x---. 3 oracle oinstall 4096 Jun 17  2014 dbca
[root@rhel12c1 cfgtoollogs]# chmod 770 dbca
[root@rhel12c1 cfgtoollogs]# ls -l

One thing strange that was observed was complaining about the permission of the block devices used for ASM disk group.

As this is an upgrade the ASM instance was created long ago and permission has been validated. This failed message appeared during several runs of the cluvfy but went away on its own. The correct permission group is asmadmin if it has been designated as the ASM admin group when cluster was created.
RACcheck has been replaced with orachk (refer ORAchk - Health Checks for the Oracle Stack (Doc ID 1268927.2)) which could also be used for pre upgrade checks with the command
./orachk -u -o pre
The output from the cluvfy with upgrade option is given below
./runcluvfy.sh stage -pre crsinst -upgrade -rolling -src_crshome /opt/app/12.1.0/grid -dest_crshome /opt/app/12.1.0/grid2 -dest_version 12.1.0.2.0 -fixup -verbose

 At this stage of upgrade, the OCR has changed.
 Any attempt to downgrade the cluster after this point will require a complete cluster outage to restore the OCR.

2015/01/13 16:44:50 CLSRSC-541:
 To downgrade the cluster:
 1. All nodes that have been upgraded must be downgraded.

2015/01/13 16:44:50 CLSRSC-542:
 2. Before downgrading the last node, the Grid Infrastructure stack on all other cluster nodes must be down.
