Is this a brand new LUN, never been used before ? (and it has no data).<br />
<br />
If so, it's Format the disk - Create a new datastore.<br />
<br />
You are adding new storage. e.g. new LUN and datastore.

Hi all,

Esxi 5.1 EMC VNX on firbe.

Cannot add LUN to more than one host

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.
