You may have already found a solution.  

  1. You may not drop the pointers at the O/S level. ASM has some header information that will have to be removed using a dd command
  2. You can mount an ASM diskgroup using the ALTER command

ALTER DISKGROUP FAS980DG1 MOUNT; Hope this helps.

Anyone have an idea how to drop a dismount ASM disk group? I can't mount it and also can't drop it?

SQL> select group_number, name, STATE from v$asm_diskgroup;

GROUP_NUMBER NAME STATE

------------ ------------------------------ -----------
1 SUN6130ORACLE1 MOUNTED
2 SUN6130ORACLE2 MOUNTED
0 ORACLEGROUP1 DISMOUNTED
0 FAS980DG1 DISMOUNTED
0 ORACLEGROUP2 DISMOUNTED SQL> drop diskgroup ORACLEGROUP1;
drop diskgroup ORACLEGROUP1
*

ERROR at line 1:
ORA-15039: diskgroup not dropped
ORA-15001: diskgroup "ORACLEGROUP1" does not exist or is not mounted

SQL> alter diskgroup ORACLEGROUP1 mount; alter diskgroup ORACLEGROUP1 mount
*

ERROR at line 1:
ORA-15032: not all alterations performed ORA-15024: discovered duplicately numbered ASM disk 0
