ADD STORAGE TO VMWARE MACHINE

I have a client that is using a Dell R720 with a MD1200 attached,  He just added another MD1200 and daisy chained it off the initial MD1200.  The server it is attached to is using VMWARE with three Datastores and 2 virtual servers.  When logging in and trying to expand the MD1200 it says there is no free disk space.
How can we get the VMWARE to see the new storage on the MD1200?

Can you see the new storage if you try to Add Storage to ESXi ?

I assume you have selected properties of the datastore and selected Expand/Increase ?

Thank you for the quick response.  I did try to Expand/Increase the datastore but it said there is no devices with free space.  I am logged in remotely so I cannot access the startup on the virtual machine

You add storage to the host, not the virtual machine.

Later you can add space to the guest virtual machine.

If you just click Add Storage does it detect the new MD1200 attached ?

No, it is not seeing it

Unfortunately, I was not notified until it had been added (daisy chained) and I was told what he did and that I had to fix it! Just love it when that happens. :-)

So if you click Add Storage in ESXi it does not even see it either ?

You are going to have to EXPAND the current MD1200 to use the new MD1200 space, and then afterwards expand the datastore in ESXi.

(or create a new VD using the new MD1200), and add that as a new datastore.

You can use OSMA to do this.

Make sure you backup first.

Thanks. I will give that a shot

You can probably create the storage via iDRAC if OMSA is not installed.

Attached is a print screen of the Host configuration via Web browser. vCenter Server is not installed.  Is there a way to get the additional MD1200 to show as this is the VM it is connected to.  While we see the initial MD1200 as stated, we are still unable to see the added MD1200.  I am sending two screen shots since it does not allow me to attach but one at a time

I'm afraid at present this has got nothing to do with the configuration of ESXi.

You need to manipulate the configuration and expand the MD1200 using Dell utilities.

When you startup the server at POST, do you have the ability to go into the Storage Controller BIOS (e.g. CTRL-R) and make modifications there, only when you have added the MD1200 to the existing MD1200, will you be able to expand the existing VMFS datastore in ESXi using the Web Browser.

Should need to do it in POST; OMSA or iDRAC ought to do the job.

Thanks for all the assistance.  I think I found the problem.  I checked with their in-house IT person and all he did was add the new MD1200.
 However, he did not set up a new array in the bios on the machine.  That should fix the issue.  If not, I will open a new question.

You don't need to use BIOS! And if you have local storage without OMSA then you're just looking for trouble.

Ok.  Thanks for the heads up.  I will make sure he is aware of your comment.  He does the hardware and I do not want to get involved in that area other than add the new VM to the host.

Ask him to complete hardware bit, it could take a while to expand the existing array to include the new MD1200.

Why can't he (or the asker) do it remotely Andrew?

I will make sure he is advised to do it after hours.  Thank you again for your help!
