Hitachi G200 - Global Storage Virtualization

• If a data path failure occurs, remove the failure, and then migrate the
volume.
• If an external volume or a DP-VOL is used, information from before the
volume is migrated displays in the secondary system Device Manager -
Storage Navigator window. If the Volume Migration is completed and the
TC pair is split and resynchronized, the volume's information is updated.
• Do not migrate P-VOL and S-VOL at the same time, or a host I/O timeout
will occur.
• Do not change the status of a volume during migration; the status may
not change.
Global storage virtualization
You can create TC pairs by using virtual storage machine volumes. The virtual
LDEV ID is displayed on Device Manager - Storage Navigator, but you cannot
perform pair operations by specifying the virtual LDEV ID. When you perform
TC pair operations, specify the physical LDEV ID of the volume. You cannot
delete the virtual LDEV ID of the volume used in TC.
