Preparing to Map Storage Controllers to Disk Devices

This section provides steps on mapping your virtual disk devices to SATA and Virtio-SCSI storage controllers for use with VSI OpenVMS on a KVM virtual machine.

Important

  • On KVM, OpenVMS supports only SATA and Virtio-SCSI controllers.

  • Starting with E9.2-4, VSI OpenVMS supports both SATA and Virtio-SCSI virtual CD/DVD-ROM devices.

  • KVM supports a maximum of six disk devices per one SATA controller and a maximum of 255 devices per one Virtio-SCSI controller. VSI does not recommend mapping more than six disk devices to either a SATA or a Virtio-SCSI storage controller.

  • SCSI devices with a LUN number higher than 7 (or more than 8 devices) are not supported by the OVMF Virtio-SCSI driver and will not appear as bootable devices in the Boot Manager.

Make sure that your VM is shut down before you assign storage controllers to your virtual disk devices.

To map SATA devices, refer to the SATA Controllers section.

To map SCSI devices, refer to Virtio-SCSI Controllers section.
