9.2.7.2

Set Host-LU QoS

This function assigns a LU QoS group to a "Host - CA Port - LUN Group" on which the host affinity setting has
been configured. A bandwidth limit (the maximum performance limit) is configured to each host LUN in a LU
QoS group.

This function can be used, irrespective of whether the Host-LU QoS has been enabled or disabled. 
However, if the Host-LU QoS has been disabled, the host starts operating within the configured 
bandwidth limit after the Host-LU QoS is enabled. 

When assigning a LU QoS group to the "Host - CA Port - LUN Group", check the number of host LUNs and 
the current usage for the LUN group, and assign the appropriate LU QoS group.

Before executing the [Set Host-LU QoS] function, configure a bandwidth limit on each host LUN. Refer to 

 for details. 

When checking the number of host LUNs and the bandwidth limit of each LUN in the LU QoS group, refer 
to 

Configure a bandwidth limit on each host. Refer to the following sections for details:
