5.7 Host-LU QoS
A list of the registered Host-LU QoS groups is displayed.
The Host-LU QoS list shows the association between "Host", "CA Port", and "LUN Group", bandwidth limit
(performance limits), and performance information.
• The ETERNUS DX60 S3 does not support this function.
• When using ETERNUS Web GUI, schedule settings for QoS parameters and displaying scheduled QoS
parameters are not available. Use ETERNUS CLI to check the scheduled QoS parameters that are specified
using ETERNUS CLI. ETERNUS Web GUI displays the bandwidth limit and the performance information
that are specified by using ETERNUS Web GUI.
• Host-LU QoS does not support from LUN#1024 onward. If volumes are mapped from LUN#1024 onward,
only the first 1024 LUNs (LUN#0 - LUN#1023) are displayed.
• Whether the QoS mode is enabled or disabled can be checked in the action field. Refer to "Enable/Disable
QoS" in "ETERNUS Web GUI User’s Guide (Settings)" for details.
• Host-LU QoS starts its operation by configuring the bandwidth limit on a "hosts", "CA ports", or "LUNs",
and enabling the QoS mode.
• This function displays the performance information that is obtained during performance monitoring
regardless of whether the QoS mode is enabled or disabled. When the performance information is
displayed before stopping performance monitoring, the performance information that is obtained from
the start time until the time when displaying the performance information is requested is displayed. This
function displays the total performance information for the host and the performance information for
each host LUN.
• The performance information of each CA port can also be displayed. Refer to "5.7.7 Port QoS (Basic)"
(page 284) for details.
