Host Group filtering rules

The host and host group list follows these guidelines for display.

• Initiators with the same name, but seen from different storage system login history tables, are filtered to only display once. New host groups can be set on both storage systems.
• Initiators that are logged into one storage system but not another are displayed. They appear as logged out in the other storage system if they are added to the host.
• If an Initiator is already in a host group on all the storage systems where that initiator is logged in, then this initiator is filtered out of the available list. Host groups with the same name and the same contents are filtered to only show once.
• If an initiator is not in a host group on one storage system, but it is in a host group on another storage system, both the initiator and the host group are shown in the list.
• Host groups with the same name but different contents are shown individually with “Sym” and the last three digits of the storage system that is appended to the name.
• Host groups with different names but the same contents across different storage systems display individually.
• If an initiator that is not in a host group has the same name as a host group on a different storage system, then the host group is appended with (Group).
• Cascaded host groups are filtered out.
