some HDS storage systems, an additional “nickname” attribute is available to be set on the HSG and its value is stored on the device itself. The management server uses the “name” attribute instead of the “nickname” attribute because not all HDS storage systems support setting the “nickname” attribute.
HP MSA and EVA Storage Systems
•You can have one initiator per host security group
•You can have 0 to multiple volumes in a host security group.
•A host security group spans all ports on the array.
IBM Storage Systems
•To assign a host mode to a host security group, you must modify a property, as described in ”Setting the Host Mode for IBM Storage Systems” on page 339.
•You can name a host security group on IBM storage systems. The host security group will be given the name of the initiator you select for the host security group.
•The management server can read the names of HSGs created by the native tool.
•Only one initiator per host security group.
•The volume can be assigned to more than one initiator.
•You can select any number of ports from one to all when creating the HSG.
•You can create the HSG with or without LUNs.
•You can add mapped and unmapped volumes to a host security group, but they should have the same host mode.
•The default is all ports are in the host security group. If no ports are selected, the default is used.
Sun 6920 Storage Systems
•You can have two or more initiators assigned to the same volume, but you can have only one initiator to a host security group.
•You can select any number of ports from one to all when creating the HSG.
•You must create the HSG with one initiator and at least one LUN.
•When the management server creates the HSG, the name of the HSG is the initiator WWN.
•The management server can read the names of HSGs created by the native tool.
•Creation of a new HSG with an initiator that already exists in another HSG adds the volumes to the previously created HSG.
•The management server displays the ports connected to the initiator you selected for creating an HSG. If the initiator is not connected to any ports, no ports are displayed.
•If you select a number of ports, only the selected initiators will be part of the host security group.
•Only the storage ports connected to the initiator in the host security group will be included in the host security group, even if the default is all ports. For example, if an initiator is not connected to a storage system, no ports will be in the host security group.
