I have successfully created the diskgroup and mounted
please find the logs below:
asmtool -list
NTFS                             \Device\Harddisk0\Partition1              100M
NTFS                             \Device\Harddisk0\Partition2            99900M
NTFS                             \Device\Harddisk0\Partition3           376938M
ORCLDISKDATA                     \Device\Harddisk1\Partition1             1022M
ORCLDISKDATA1                    \Device\Harddisk2\Partition1             1022M
C:\Windows\system32>sqlplus / as sysasm
SQL> select DISK_NUMBER,path from v$asm_disk;
DISK_NUMBER PATH
          1 \\.\ORCLDISKDATA
          0 \\.\ORCLDISKDATA1
SQL> select NAME,STATE,TYPE,TOTAL_MB,FREE_MB from v$asm_diskgroup;
NAME                           STATE       TYPE     TOTAL_MB    FREE_MB
DATA                           MOUNTED     NORMAL       2044       1942
Now I am connected to sysdba and firing the command to create database it's showing me the following error :
create database testdb
ERROR at line 1:
