Hello guys,
I am setting up 3 node RAC for Oracle 12c (12.2) using Oracle Linux 7.4 (please note the version 7.4 and not 7.0 or 7.1). This setup is being done on Oracle VM Server 3.4.4 platform with shared storage. Has any one attempted this or anything very close with this version, platform mix.
Each RAC node is a VM with the following Specification:
- Oracle Linux 7.4
- Two vNIC ( 1 for public and 1 for private)
- Four (4) Virtual Disks (vDisk)
- One for Local Storage: 180GB and not shared
- Three (3) vDisk each with 1TB to be used for ASM and shared among the three RAC Nodes
- 4 vCPU @ 2.0GHz
- 8GB RAM (for starters; will increase as required)
The issue is that whilst configuring the node, I realized that the Virtual Disks are presented as xvda, xvdb, xvdc xvdd within the ole 7.4. Following the steps to configure persistent device naming for the virtual disk using udev is posing a bit of a challenge since running the command /usr/lib/udev/scsi_id -g -u -d /dev/xvdb does not return any unique id which can be used for setting the udev rules required for persistent naming for the ASM setup.
Does anyone have any idea how to get around this? All the example of RAC installation I have come across online are on Virtual Box using Ole 7.0 to 7.3. Virtual Box virtual disk creation allows for scsi type disk to be created.
Any workarounds, pointer or ideas will be deeply welcome.
Thanks in advance
Alfi
