    Hey, hope you are doing well.
    Let me see if I got it correctly: 
    You have 3 hosts all with local disks as datastores and you also have a MSA array (which I assume is presented to the hosts, please clarify)
    What you want is to add more disks to one of the hosts (let's name it host 1) and consume it from other host (either host 2 or 3)?

    If that's the case, you won't be able to do it without any additional products.
    It's also not a good idea to have VMs residing on local datastores. 

    What you can do, if you meet the requirements is to configure vSAN in the cluster, that way all the local storage from the three hosts will be pooled into a single datastore.
    BUT there is a catch.
    1. All your hosts have to be in compatible with vSAN
    2. You have to have SSD disks available.
    3. You have to get a vSAN license.

    If you don't meet those requirements, I dont think you will be able to do it.

    Hi thank you for respond
    i have 3 host but anyone has no local disk
    all of them use lan on MSA2050
    all host connect to msa
    but at this time we need to add 10TB HDD to one of my host
    so i want to know for example if i add 10TB HDD in host 1, one of my machine in host 2 can access this new 10TB hard disk or not?

    Short answer: no.

    Long answer: you might create a VM to reside in the host with the 10TB disk, create a file share and let other VMs consume that file share.
    Still, you won't be consuming that storage at the hypervisor level, you will be consuming it at the Operating systme level but maybe that works.
