Abstract:
In one aspect, a method includes obtaining data on components of a virtualization server comprising acquiring a mapping of virtual disks in a virtual store to storage disks, obtaining data on components of a storage array comprising acquiring a mapping of logical units in the storage array to the storage disks, the logical units replicating data from a corresponding storage disk, correlating each virtual disk to a logical unit based on the mapping of the virtual disks to the storage disks and the mapping of the logical units to the storage disks, retrieving replication data of the logical units from the storage arrays and, for a selected virtual store, checking that the selected virtual store has a replica for all the required storage disks mapped to the virtual disks of the selected virtual store.
