Dell PowerStore Configuring Volumes

Hosts and host group configurations

Host configurations are logical connections through which hosts or applications can access storage resources. Before a host can access storage, you must define a configuration for the host and associate it with a storage resource.

You can pool individual hosts together into a host group. A host group is a collection of hosts that enables you to perform volume-related operations across all the hosts in the group. For example, when you provision volumes for a host group, the volumes become available to all member hosts. A host group uses an iSCSI or Fibre Channel connection. It cannot use both.

Under Compute, click Hosts Information to perform the following actions:

• Manage hosts and host groups.
• Review the storage resources that are mapped to individual hosts or host groups.
• Review the initiators that are associated with the existing host configurations.
• For host groups, you can also add more hosts.

You can configure host access to volumes, volume groups, and thin clones when you initially create them or, later, from the relevant Details page. Go to one of the following screens:

• If you are creating a storage resource, in the Create wizard, go to the Host Mappings screen.
• For existing storage resources, select the Host Mappings tab on the Details page of the relevant storage resource.
