Select the Initiator Groups tab on the Storage Edge Configuration page to view groups and their member initiators. Core uses the concept of appliance storage groups, called initiator groups. This common practice is also known as LUN masking or storage access control. Initiator groups are a way for storage administrators to group LUNs according to the parameters of the environments or servers they serve. We recommend configuring initiator groups on the Core to only group iSCSI initiators that need to access or modify the same LUN(s).
