ORA-15063: ASM discovered an insufficient number of disks for diskgroup

 
When Start the Database getting error.
 
 
 
SQL> startup
ASM instance started
...
ORA-15032: not all alterations performed
ORA-15063: ASM discovered an insufficient number of disks for diskgroup "RECO"
ORA-15063: ASM discovered an insufficient number of disks for diskgroup "DATA"
 
 
 
 
Action:

 Check that the disks in the diskgroup are present and functioning, that the owner of the ORACLE binary has read/write permission to the disks, and that the ASM_DISKSTRING initialization parameter has been set correctly. Verify that ASM discovers the appropriate disks by querying V$ASM_DISK from the ASM instance
 
 
Solution:
 
 #/etc/init.d/oracleasm scandisks
Scanning the system for Oracle ASMLib disks: DISK1
                                                           [  OK  ]
 
 
 
There are two disk for ASM but it showing one disk.
 
 
$ /etc/init.d/oracleasm init
 
 
$ /etc/init.d/oracleasm listdisks
 
DISK1
DISK2
 
 
$ ls -ltr /dev/oracleasm/disk/*
 
/dev/oracleasm/disks/DISK2
/dev/oracleasm/disks/DISK1
 
 
 
 
$ cd /grid/bin
 
$ ./crsctl stop resource -all
 
$ ./crsctl start resource -all
