9.1.13 Host-LU QoS Performance Information
When a host affinity setting with a specific host group is already configured, the total performance
information for the host and the performance information of each LUN are displayed.
If a host affinity setting with all of the host groups is configured ("All" is specified as the target host group),
the performance information of each host LUN is displayed.
The following items are displayed in the Main area:
● Host - CA Port - LUN Group Information
• Host : Bandwidth Limit
The host name and the bandwidth limit of the selected host is displayed in "Host : Bandwidth Limit"
format.
If the bandwidth limit has not been configured (the bandwidth has not been limited), "Unlimited" is
displayed as the "Bandwidth Limit". If "All" has been selected for the host, a "-" (hyphen) is displayed as the
"Bandwidth Limit".
• Host Group
The host group name, to which the selected host belongs, is displayed.
If all of the hosts are to be connected, "All" is displayed.
If the host does not belong to a host group, a "-" (hyphen) is displayed.
• WWN
The WWN for the selected host is displayed.
This item is displayed when the host affinity setting is configured and the selected host is "FC" or "FCoE".
The monitoring status of the performance information and obtained performance information are cleared in
the following conditions:
• When the port mode is changed (CA, CA/RA → RA or Initiator)
• When the ETERNUS DX Disk storage system is rebooted
