Some advanced functions of the HDS Lightning are not supported by the Lenovo Storage V7000.
Advanced copy functions for HDS Lightning (for example, ShadowImage, Remote Copy, and Data Migration) are not supported for disks that are managed by the Lenovo Storage V7000, because the copy function does not extend to the Lenovo Storage V7000 cache.
The HDS Lightning 99xxV supports Logical Unit Expansion (LUSE). LUSE is not a concurrent operation. LUSE is accomplished by concatenating between 2 and 26 existing logical units (LUs) together. Before LUSE can be performed on an LU, the LU must be removed from the storage pool and unmapped from the Lenovo Storage V7000.
TrueCopy operations are functionally similar to Metro Mirror. TrueCopy processing is not supported when the disk controller system is used with the Lenovo Storage V7000. Even when an HDS Lightning 99xxV is shared between a host and a Lenovo Storage V7000, TrueCopy processing is not supported on the ports that are zoned directly with the host.
The HDS Lightning 99xxV supports Virtual LVI/LUNs. Virtual LVI/LUNs is not a concurrent operation. Virtual LVI/LUNs allows you to divide LUNs into several smaller virtual LUNs for use by the HDS Lightning. You must first create existing LUNs into free space and then define their own LUNs using that free space. Virtual LVI/LUNs must not be managed or mapped to a Lenovo Storage V7000.
LUNs that are set up using either LUSE or Virtual LVI/LUNs appear as normal LUNs after they are created. Therefore, LUNs that are set up using LUSE or Virtual LVI/LUNs can be used by the Lenovo Storage V7000 after they are created.
LUs cannot be explicitly set to write-protected. However, some of the advanced features, such as Metro Mirror, can be used to write-protect an LU as part of the function. Metro Mirror must not be used for LUs that are in use by a Lenovo Storage V7000.
