Viewing hosts
The Hosts topic shows a tabular view of information about initiators, hosts, and host groups that are defined in the system. For
more information about hosts, see About initiators, hosts, and host groups. The Hosts topic also enables users to map initiators
and view map details.
Hosts table
The hosts table shows the following information:
NOTE: The table shows 10 entries at a time by default.
● Group. Shows the group name if the initiator is grouped into a host group; otherwise, --.
● Host. Shows the hostname if the initiator is grouped into a host; otherwise, --.
● Nickname. Shows the nickname that is assigned to the initiator.
● ID. Shows the initiator ID, which is the WWN of an FC or SAS initiator or the IQN of an iSCSI initiator.
● Profile. Shows Standard, which is the default profile setting.
● Discovered. Shows Yes for a discovered initiator. Shows Yes for an initiator that is currently not logged into the system.
● Mapped. Shows Yes for an initiator that is mapped to volumes, or No for an initiator that is not mapped.
● Host Type. Shows the host interface protocol.
Related Maps table
For selected initiators, the Related Maps table shows the following information. By default, the table shows 20 entries at a time.
● Group.Host.Nickname. Identifies the initiators to which the mapping applies:
○ initiator-name—The mapping applies to this initiator only.
○ initiator-ID—The mapping applies to this initiator only, and the initiator has no nickname.
○ host-name.*—The mapping applies to all initiators in this host.
○ host-group-name.*.*—The mapping applies to all hosts in this group.
● Volume. Identifies the volumes to which the mapping applies:
○ volume-name—The mapping applies to this volume only.
