Note: Zone 3 is configured for use with tape (3592 with WORM cartridges are recommended - ports
Zones 4 & 5 are configured for use with data replication (DS4100 enhanced remote volume mirroring) Per IBM recommendations, the ports used to connect the switches are not included in the zones for remote mirroring
NOTE: It is recommended to have a plan of action before installing and using RVM. Here are a couple of RVM related questions you may want to ask yourself before installing and using RVM. This list is just some examples and is not complete. Each administrator knows their systems and is encouraged to compile procedures related to their environment and RVM.
The DR550 is set to manual synchronization by default and should be left as is. As a system administrator you want to be able to tell it when to sync up to be able to control data integrity. Understanding which site is the primary and which is the secondary site is critical. How does it change in the event of replication disruption?
In the event that disruption in replication does occur at the primary site, does the secondary site become the permanent primary site?
Do you move to secondary site if disruption in replication does occur at primary site and when primary is fixed move everything back to primary?
Are backups being used at one or both sites?
Speed of replication depends on many factors, including replication settings, distance link between sites, speeds, etc. Daily updates to secondary site are fairly quick but a total resynchronization will take longer. Do you have an idea of these times?
