Enabling datastore mounting across different subnets

If you use iSCSI or NFS and the subnet is different between your ESX hosts and your storage system, you need to modify two settings in the Virtual Storage Console for VMware vSphere preferences files. Otherwise, provisioning will fail because VSC cannot mount the datastore.

About this task

When datastore provisioning fails, VSC logs the following error:

Unable to continue. No ip addresses found when cross-referencing kernel ip addresses and addresses on the controller.

Unable to find a matching network to NFS mount volume to these hosts.

Steps

  1. Open the following files in a text editor:
    VSC_install_dir\etc\kamino\kaminoprefs.xml
    VSC_install_dir\etc\kamino\kaminosdkprefs.xml
  2. Update both files as follows:
    If you use... Do this...
    iSCSI Change the value of the entry key default.allow.iscsi.mount.networks from ALL to your ESX host subnet masks.
    NFS Change the value of the entry key default.allow.nfs.mount.networks from ALL to your ESX host subnet masks.
    The preferences files include example values for these entry keys.
    Note: ALL does not mean all networks. It means that all matching networks between the host and storage system can be used to mount datastores. Specifying subnet masks enables mounting across the specified subnets only.
  3. Save and close the files.
