Hi Guru's
OS: RHEL5
DB: 11.2.0
Today i am facing a strange proble while creating Diskgroup in ASM. The scenerio is like :
I create disk partitions from 1-7 during installing 11gr2 db with grid and cretate the disk group DATA and FRA using ASMCA. but after completeing all installation db as well as grid later on i add 4 disks and start the server. and add those disk by using oracleasm create disk commad and check the disks are properly listed while checking using oracleasm listdisks
But when i try to create disk group using command prompt:-
SQL> CREATE DISKGROUP DATA1
EXTERNAL REDUNDANCY
DISK '/dev/oracleasm/disks/ASMDATA10';
I am getting error as:-
ORA-15018: diskgroup cannot be created
ORA-15031: disk specifications '/dev/oracleasm/disks/ASMDATA10' matches no disks
ORA-15014: path '/dev/oracleasm/disks/ASMDATA10' is not in the discovery set
But when i try to create the diskgroup using asmca i am able to create the disk group DATA1
why this is happening
any idea about the same
Thanks in advance.
