ASM Disk Space

 Hi,

We have implemented Oracle 10g R2 RAC on HP-UX(IA-64) with Database on ASM.

We have two disk groups DATA_DISK of 1024 GB & ARC_DISK of 100GB each containing one disk of the same size.

Last month I added 200GB Disk (DATA_DISK_0001) to the DATA_DISK diskgroup and when I check the v$asm_disk and v$asm_diskgroup I get the followig:

SQL> select name,round(total_mb/1024)"Group Size in GB",round(free_mb/1024)"Group Free in GB" from v$asm_diskgroup;

NAME                           Group Size in GB Group Free in GB
------------------------------ ---------------- ----------------
ARCH_DISK                                   100               80
