ACTUAL BEHAVIOR
---------------
2 new X4-2 Exadata Storage Servers were added into the X3-2 Exadata Quarter Rack
X4-2 Exadata Storage Servers have hard disks larger than X3-2 Exadata Storage Srerver.
Hence, each hard disk in X4-2 Exadata Storage Servers has 500G free space which remains after customer added new ASM disks from X4-2 Exadata Storage Servers into the existing ASM disk groups
So my customer wants to create a new ASM disk group 'DATA2' using the remaining disk partitions.
My customer failed to create a new ASM disk group hitting the following errors
ORA-15018: diskgroup cannot be created
ORA-15031: disk specification 'o/X.X.X.9/DATA2*' matches no disks
ORA-15031: disk specification 'o/X.X.X.7/DATA2*' matches no disks
