Neben den VMs für die beiden RAC-Knoten benötigen wir noch eine Shared Storage Konfiguration. Sobald die VMs ausgeschaltet sind, können in Virtualbox unter Windows sechs 10 GB Disks angelegt werden:
"C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" createhd --filename C:\vm\shared\asmdisk01.vdi --size 10240 --format VDI --variant Fixed "C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" createhd --filename C:\vm\shared\asmdisk02.vdi --size 10240 --format VDI --variant Fixed "C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" createhd --filename C:\vm\shared\asmdisk03.vdi --size 10240 --format VDI --variant Fixed "C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" createhd --filename C:\vm\shared\asmdisk04.vdi --size 10240 --format VDI --variant Fixed "C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" createhd --filename C:\vm\shared\asmdisk05.vdi --size 10240 --format VDI --variant Fixed "C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" createhd --filename C:\vm\shared\asmdisk06.vdi --size 10240 --format VDI --variant Fixed
Anbindung der Disks an die VMs:

Nach dem Start der Cluster-Knoten, müssten nun die neuen Disks via fdisk sichtbar sein:

Um die Disks für den ASM Filer Driver zu labeln entpacken wir die Grid Infrastructure Software im Grid Home als OS-User grid:
[grid@ol73o122-1 ~]$ cd /opt/oracle/grid [grid@ol73o122-1 grid]$ unzip -q /media/sf_transfer/linux_12201/linuxx64_12201_grid_home.zip
Das Labeln erfolgt wieder als root:
[root@ol73o122-1 dev]# export ORACLE_HOME=/opt/oracle/grid [root@ol73o122-1 dev]# export ORACLE_BASE=/tmp [root@ol73o122-1 dev]# /opt/oracle/grid/bin/asmcmd afd_label DATA1 /dev/sdb --init [root@ol73o122-1 dev]# /opt/oracle/grid/bin/asmcmd afd_label DATA2 /dev/sdc --init [root@ol73o122-1 dev]# /opt/oracle/grid/bin/asmcmd afd_label DATA3 /dev/sdd --init [root@ol73o122-1 dev]# /opt/oracle/grid/bin/asmcmd afd_label DATA4 /dev/sde --init [root@ol73o122-1 dev]# /opt/oracle/grid/bin/asmcmd afd_label DATA5 /dev/sdf --init [root@ol73o122-1 dev]# /opt/oracle/grid/bin/asmcmd afd_label DATA6 /dev/sdg --init
