In the Oracle VM environment, access groups are SAN hosts or Host Groups when an Access Group has initiators from two or more Oracle VM Manager Servers, which can be considered collections of one or more storage initiators. A physical disk can only be accessed by a SAN host, and the access group enables access to the physical disk by that SAN host. The initiators in an access group are the initiators on an Oracle VM Server. Access groups enable you to expose a physical disk to a specific Oracle VM Server. You create the access groups through the Oracle VM Manager.
The Oracle VM Storage Connect Plug-In for Oracle Flash Storage Systems automatically creates an access group for each SAN host on an Oracle FS System.
A single access group represents a single host.
Before presenting (mapping) an access group to an Oracle FS System physical disk, add the initiators to the access group.
When you present an Oracle FS System physical disk to an access group, Oracle VM automatically assigns the physical disk the next available physical disk number.
After adding a new access group, you need to refresh the Oracle FS System SAN server for it to recognize the new access group.
For information about creating and deleting access groups, refer to the Oracle VM documentation on the Oracle Technical Network (http://docs.oracle.com).
