Hi Guru's



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:-




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.
