Example 6 with HostDatastoreSystem

use of com.vmware.vim25.mo.HostDatastoreSystem in project cloudstack by apache.

the class VmwareStorageProcessor method cleanUpDatastore.

/**
 * 1) Possibly expand the datastore.
 * 2) Possibly consolidate all relevant VMDK files into one VMDK file.
 * 3) Possibly move the VMDK file to the root folder (may already be there).
 * 4) If the VMDK file wasn't already in the root folder, then delete the folder the VMDK file was in.
 * 5) Possibly rename the VMDK file (this will lead to there being a delta file with the new name and the
 *    original file with the original name).
 *
 * Note: If the underlying VMDK file was for a root disk, the 'vmdk' parameter's value might look, for example,
 *  like "i-2-32-VM/ROOT-32.vmdk".
 *
 * Note: If the underlying VMDK file was for a data disk, the 'vmdk' parameter's value might look, for example,
 *  like "-iqn.2010-01.com.solidfire:4nhe.data-32.79-0.vmdk".
 *
 * Returns the (potentially new) name of the VMDK file.
