344 Implementing the IBM Storwize V7000 with IBM Spectrum Virtualize V8.2.1
From the Host Clusters view, many options are available to manage and configure the host 
cluster. These options are accessed by selecting a cluster and clicking Actions (see 
Figure 8-24).
Figure 8-24   Host Clusters Actions menu
From the Actions menu, we can perform the following tasks:
/SM590000View Hosts status within the cluster.
/SM590000Add or Remove Hosts from the cluster.
/SM590000Rename the host cluster.
/SM590000Modify Shared Volume mappings allows you to add or remove volumes mapped to all 
hosts in the cluster while maintaining the same SCSI ID for all hosts.
/SM590000Modify Host Type can be used to change from generic to VVOLs, for example.
/SM590000Modify I/O Groups for Hosts is used to assign or restrict volume access to specific I/O 
groups.
/SM590000Edit Throttle is used restrict MBps or IOPS bandwidth for the Host Cluster.
/SM590000View All Throttles displays any throttling settings and allows for changing, deleting, or 
refining Throttle settings.
8.4.3  Advanced host administration
This section covers host administration, including topics, such as host modification, host 
mappings, and deleting hosts. Basic host creation by using FC and iSCSI connectivity is 
described in 8.4.1, “Creating hosts” on page 327.
It is assumed that hosts were created in your IBM Spectrum Virtualize GUI, and that some 
volumes are mapped to them. This section describes the following functions that are available 
in the Hosts section of the IBM Spectrum Virtualize GUI (see Figure 8-25 on page 345):
/SM590000Hosts (“Modifying Volume Mappings” on page 346)
/SM590000Ports by Host (8.4.4, “Adding and deleting host ports” on page 361)
/SM590000Host Mappings (8.4.5, “Host mappings overview” on page 371)
