Have you installed ESXi on the same LUN as datastore1 ?

Because ESX is running from the same LUN as the Datastore 1 possibly.

Have you installed ESXi on the same LUN as datastore1 ?

<div>
I haven't configured that server but I'm being told that ESXi was installed on the locally attached storage. <br />
Please see the screenshot. <br />

Hello,<br />
<br />
I would like to extend size of a datastore on an ESXi 4.0 machine. There are two LUNs configured and two datastores using them. Datastore 1 is running out of space and I would like to add free space from datastore 2. However when I go to Datastore 1 --&gt; Proprties --&gt; Increase then the &quot;Increase Datastore Capacity&quot; window is completely blank. The question is - why? <br />
Is that because I need an empty LUN to use for the expansion or is it bacause the ESX is running from the same LUN as the Datastore 1?<br />
<br />
Kind Regards<br />

Hello,

I would like to extend size of a datastore on an ESXi 4.0 machine. There are two LUNs configured and two datastores using them. Datastore 1 is running out of space and I would like to add free space from datastore 2. However when I go to Datastore 1 --> Proprties --> Increase then the "Increase Datastore Capacity" window is completely blank. The question is - why? 
Is that because I need an empty LUN to use for the expansion or is it bacause the ESX is running from the same LUN as the Datastore 1?

VMware datastore expansion

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.
