Hello

we are using oracle database 10.2.0.1 (RAC with two instaces).

And using one diskgroup called (DATA) with two disks (DATA_0000,DATA_0001)

one of the instances is mounted (working fine +ASM1) but the other one not mounted (+ASM2)

when I tried to mount it force it gives me the following error:-

sql> alter diskgroup DATA mount;

alter diskgroup DATA mount

*

ERROR at line 1:

ORA-15032: not all alterations performed

ORA-15040: diskgroup is incomplete

ORA-15042: ASM disk "1" is missing

------------------------------------------------------------------------------------------------------------------------------------------

Here is some details about our system:-

sql>select NAME,GROUP_NUMBER,STATE,TYPE from v$asm_diskgroup;

NAME GROUP_NUMBER STATE TYPE
