Okay, I did wonder because 5.x, has a new facility to check what is in use, before it un-mounts and deletes.<br />
<br />
Have you checked for content, at the console or SSH?<br />
<br />
It's not in use by HA ?<br />
<br />
Storage I/O Control ?

<div>
Well there are 3 host using it but like I said I was able to delete the other 3 new datastores without any errors but this one gives me the error.<br />
How can I check for storage I/o control

It should state enabled for the datastore in the client.

no it says disabled for that..

do you have other LUNs on this host from the same SAN?

do you have other LUNs on this host from the same SAN?

<div>
yes and they are working fine..<br />
Like I said I created 4 new datastores yesterday but did not use them and then wanted to delete them today and was able to del 3 out of the 4..

<div>
but if I do that, wont it leave the datastore as greyed out on the vmhost?<br />
I thought you were supposed to delete the datastore first before removing the lun from the san?

<div>
In fact you are suppose to do lots of things, e.g. LUN masking, to stop iSCSI hanging, but that only became an issue in 5.x.<br />
<br />
otherwise it's long and involved at the SSH or console prompt, trying to find the process, and shut it down.

<div>
So is ok to remove the lun from the san and then do the hba rescan and will this remove the datastore or will it stay on the host but greyed out?

That's a 50/50 question.<br />
<br />
if it is &quot;in use&quot; it will remain grayed out.

That's a 50/50 question.

if it is "in use" it will remain grayed out.

<div>
No it is not is use which is why I don't understand why it gives me an error when trying to delete it..<br />
Nothing ever is easy is it?? lol

That worked. Thanks once again Andrew...

Getting an error when trying to delete a vmware datastore

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.

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.
