Last updated on SEPTEMBER 29, 2017

Applies to:

Exadata X3-2 Hardware - Version All Versions to All Versions [Release All Releases]
Linux x86-64

Symptoms

On : NA version, MICC Transfer to TSC

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

Changes

2 new X4-2 Exadata Storage Servers were added into the X3-2 Exadata Quarter Rack
