Thanks for the info but I don't think that these articles apply. &nbsp;The Ubuntu OS is a VM that is hosted by two ESX hosts that are mapped to the volume that I want to map to the VM. &nbsp;As I understand it, the ESX hosts make the connection to the iSCSI volume on the SAN and then from within VMware, you add this RDM to the VM. &nbsp;The SAN volume should show up on the VM as a SCSI disk (sdb, not iSCSI). &nbsp;I need to know how to mount this drive. &nbsp;

It showed up as sdb so I was able to run fdisk and mkfs and now it is usable. &nbsp;

I already configured the Vmware side of this and the SAN volume is being presented to the Ubuntu VM. &nbsp;I'm now trying to get the Ubuntu OS to see the volume. &nbsp;Do I have to setup some sort of Initiator? &nbsp;

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

Storage

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.

Linux is a UNIX-like open source operating system with hundreds of distinct distributions, including: Fedora, openSUSE, Ubuntu, Debian, Slackware, Gentoo, CentOS, and Arch Linux. Linux is generally associated with web and database servers, but has become popular in many niche industries and applications.
