[INS-40916] Single-instance versions of Cluster Synchronization Services (CSS) are detected.

Cause:

The error occurs while installing RAC software and already an existing single instance oracle restart is present on the host which prevents the installation 

Cause - The installer detected single-instance versions of Cluster Synchronization Services (CSS) on the following nodes in the cluster:exdbadm02  

Action - Before proceeding with the installation, you must deconfigure CSS, shut down any Oracle Automatic Storage Management (Oracle ASM) instances, and shut down all databases that use Oracle ASM for storage on all of the listed nodes. Oracle Clusterware installation starts a cluster-wide version of CSS. After Oracle Clusterware installation is complete, you may start up any databases and Oracle ASM instances that previously used CSS. When they are brought back up, Oracle Clusterware provides CSS.

Workaround:

Check the single instance oracle restart configuration on the server

[root@exdbadm02 oracle]# ps -ef|grep has
root      4198     1  0 16:59 ?        00:00:00 /bin/sh /etc/init.d/init.ohasd run
root      7046  5418  0 17:25 pts/6    00:00:00 grep has

Deconfigure the existing configuration of has

[root@exdbadm02 install]# ./roothas.pl -deconfig -force

Deinstall the grid software

[oracle@exdbadm02 deinstall]$ ./deinstall

Now proceed to install RAC

CELL-02559: There is a communication error between MS and CELLSRV.

Cause:

CellCLI> create griddisk MGMT_CD_cell12_stocell celldisk=CD_cell18_stocell,size=976M

CELL-02559: There is a communication error between MS and CELLSRV.

Workaround:

Check if all the three cell services (cellsrv,MS and RS)are up and running

CellCLI> list cell detail
.
.
.
         cellsrvStatus:          running
         msStatus:               running
         rsStatus:               running

If any service state is not running, then start the services

[root@exceladm00 raw]# service celld restart
