The IBM System Storage Support for Microsoft Volume Shadow Copy Service and Virtual Disk Service software maintains a free and a reserved pool of volumes. Because these objects do not exist on the Lenovo Storage V7000, the free and reserved pool of volumes are implemented as virtual host systems. You must define these two virtual host systems on the Lenovo Storage V7000.
When a shadow copy is created, the IBM System Storage Support for Microsoft Volume Shadow Copy Service and Virtual Disk Service software selects a volume in the free pool, assigns it to the reserved pool, and then removes it from the free pool. This protects the volume from being overwritten by other Volume Shadow Copy Service users.
To successfully carry out a Volume Shadow Copy Service operation, there must be enough volumes mapped to the free pool. The volumes must be the same size as the source volumes.
Use the management GUI or the Lenovo Storage V7000 command-line interface (CLI) to carry out the following steps:
If you do not use the default WWPNs 5000000000000000 and 5000000000000001, you must configure the IBM System Storage Support for Microsoft Volume Shadow Copy Service and Virtual Disk Service software with the WWPNs.
