Installing OEL on Specialized Storage Device (iSCSI SAN)

When installing Oracle Enterprise Linux via graphical interface, we are given the option to install on “Specialized Storage Devices”. This is an alternative to installing on a local hard drive.

Select “Specialized Storage Devices”.

You will be presented with a list of iSCSI nodes. Check the node(s) that you wish to use, most likely one if you would have used one physical hard drive by selecting a traditional storage method.

If this install is taking place on a physical machine, then follow your hardware vendor’s instructions to boot from SAN. If it has been installed on a virtualized environment, you may have to add the iSCSI LUN where OEL was installed as a disk on your VM. In VMware, this is done through RDM (Raw Device Mapping). In your VM’s settings, select RDM Device, then click add.

Select the LUN where you installed OEL. If this list is empty, you may have to navigate to the ESXi host currently running the VM: Manage tab –> Storage –> Select the iSCSI adapter –> Rescan the host for new storage devices or VMFS volumes.
