    # Adding an ISO to `XCP-ng` Host Via Command-Line

    > **REF:** <https://linuxconfig.org/how-to-refresh-xenserver-s-storage-repository-to-include-newly-added-items>
    ## Identify ISO Link

    Copy link address from browser. `wget` ISO to local XCP-ng host. Below example is `CentOS Stream 8` from a mirror.

    > **REF:** <http://isoredirect.centos.org/centos/8-stream/isos/x86_64/>
    ```
    [10:19 oasis iso_images]# wget http://mirror.linux.duke.edu/pub/centos/8-stream/isos/x86_64/CentOS-Stream-8-x86_64-20210406-boot.iso

    If you run `xe cd-list`, the new ISO hasn't yet been recognized so we'll need to re-scan the storage repository (sr).

    ```
    [10:25 oasis iso_images]# xe cd-list
    uuid ( RO) : fcadf37b-7fad-4db1-a0c2-b1449b3e76f1
    name-label ( RW): guest-tools.iso
    uuid ( RO) : fdf30c16-4bfe-4e97-83dc-80b7928f8a77
    name-label ( RW): ubuntu-18.04.5-live-server-amd64.iso
    uuid ( RO) : ab17ffe5-0049-4d55-bd93-33b54ef479b8
    name-label ( RW): ubuntu-20.04.2-live-server-amd64.iso
    ```

    ## Re-Scan Storage Repository (SR)

    First, get the `UUID` of the relevant ISO storage repository by using `xe sr-list`. We can filter on `type=iso` to limit the output.

    ```
    [10:23 oasis iso_images]# xe sr-list type=iso
    uuid ( RO) : 190d3dff-5801-36aa-887f-3981912f9640
    name-label ( RW): XCP-ng Tools
    name-description ( RW): XCP-ng Tools ISOs
    host ( RO): oasis
    type ( RO): iso
    content-type ( RO): iso
    uuid ( RO) : 0593ee67-b5b0-0861-f20c-e2b1c8d2bc12
    name-label ( RW): ISO Images
    name-description ( RW):
    host ( RO): oasis
    type ( RO): iso
    content-type ( RO): iso
    ```

    Then, we'll use the `xe sr-scan` with the `uuid` required parameter to rescan and update the new ISO. `xe cd-list` displays the new results.

    ```
    [10:32 oasis iso_images]# xe sr-scan uuid=0593ee67-b5b0-0861-f20c-e2b1c8d2bc12
    [10:35 oasis iso_images]# xe cd-list
    uuid ( RO) : fcadf37b-7fad-4db1-a0c2-b1449b3e76f1
    name-label ( RW): guest-tools.iso
    uuid ( RO) : e5570fe5-ea6f-4f6c-848f-73300047e8f7
    name-label ( RW): CentOS-Stream-8-x86_64-20210406-boot.iso
    uuid ( RO) : fdf30c16-4bfe-4e97-83dc-80b7928f8a77
    name-label ( RW): ubuntu-18.04.5-live-server-amd64.iso
    uuid ( RO) : ab17ffe5-0049-4d55-bd93-33b54ef479b8
    name-label ( RW): ubuntu-20.04.2-live-server-amd64.iso
    [10:35 oasis iso_images]#
    ```

    Now, the new ISO will display in the Xen Orchestra UI as a bootable mount for installing a new Virtual Machine with this operating system.
