Without storage partitioning, the logical drives configured on a DS can only be accessed by a limited number of host systems datasyeet by a single cluster. DS Implementation Guide VolumeCopy is a way to provide a complete point-in-time copy of a source logical drive. It allows you to connect a much higher number of host systems, either in stand-alone or clustered mode. As opposed to FlashCopy where only the original values of changed data are copied to the repositorythe whole source logical drive is copied to target.
DS comes standard with 4 storage partitions. Expansion Unit Step 3: Therefore, the access to that LUN is exclusively reserved for that host. SAN Switches Step 8: That means once you have assigned the LUN to a host it is hidden from all other hosts connected to the same Storage Server.
