Hi,
I am using 10.2.0.3.0 on Solaris 10 Sparc 64 bit.

Currently I am using the following ASM Diskgroup:

SQL> select name,total_mb/1024, free_mb/1024
  2  from v$asm_diskgroup;

NAME                           TOTAL_MB/1024 FREE_MB/1024
------------------------------ ------------- ------------
FRA_GRP                                    5      4.34375
DATA_GRP                       4999.76563   145.303711

Now I have some 6 asm disks of size 500GB each as candidate disks.

Should I add those disks to the existing DATA_GRP or create a new diskgroup?

What do you recommend please?
