PRCS-1007 : Server pool RPPCOMS already exists

Problem:

While adding database using srvctl add database command got PRCS-1007 and PRCR-1086 errors:

$ srvctl add database -db RPPCOMS -oraclehome /u01/app/oracle/product/12.1.0/dbhome_1 -spfile +DATA/RPPCOMS/spfileRPPCOMS.ora -pwfile +DATA/RPPCOMS/PASSWORD/pwdrppcoms.256.1005727427 -dbname RPPCOMS  -diskgroup FRA,DATA

PRCS-1007 : Server pool RPPCOMS already exists
PRCR-1086 : server pool ora.RPPCOMS is already registered

Solution:

Remove mentioned server pool via root user:

# crsctl delete serverpool ora.RPPCOMS

And retry adding database service.
