Using the Performance Manager GUI 4-35
Hitachi Universal Storage Platform V/VM Hitachi Performance Manager User’s Guide
• The list near the upper right corner of the Server Priority Manager
window enables you to narrow WWNs (host bus adapters) in the list:
– If All is selected, all the WWNs appear in the list.
– If Prioritize is selected, only the prioritized WWNs appear in the list.
– If Non-Prioritize is selected, only the non-prioritized WWNs appear in
the list.
• The upper-left tree lists ports and the host bus adapters connected to these
ports in the storage system.
Ports on the storage system are shown below the Subsystem folder. The
ports are indicated by icons such as and .
When you double-click on a port, the tree expands to display two items:
Monitor and Non-Monitor. The host bus adapters that are connected to
the specified port are displayed below Monitor or Non-Monitor.
– If you double-click Monitor, the host bus adapters ( ) whose traffics
with the specified port are monitored are displayed below Monitor.
– If you double-click Non-Monitor, the host bus adapters whose traffics
with the specified port are not monitored are displayed below Non-
Monitor.
The WWN and SPM names of the host bus adapters are displayed on the
right of the host bus adapter icon ( ) below Monitor. WWNs (Worldwide
Name) are 16-digit hexadecimal numbers used to uniquely identify host
bus adapters. SPM names are nicknames assigned by the system
administrator so that they can easily identify each host bus adapter.
Only the WWN is displayed on the right of the host bus adapter icon ( )
below Non-Monitor.
When many-to-many connections are established between host bus
adapters (HBAs) and ports, make sure that all the traffics between HBAs
and ports monitored. Therefore, make sure that all the connected HBAs are
displayed below Monitor. For details on how to move an HBA displayed
below Non-Monitor to below Monitor, see Monitoring All Traffic between
HBAs and Ports.
The list on the right of the tree changes depending on the item you
selected in the tree as follows.
– When you selected a port or Monitor icon, the list displays the
information of host bus adapters that are connected to the ports(s) and
monitored by Performance Monitor.
– When you selected the Monitor icon or the Subsystem folder, the list
becomes blank.
• The lower-left tree lists SPM groups. The tree also lists host bus adapters
(WWNs) in each SPM group:
– SPM groups ( ), which contain on or more WWNs, are displayed below
the Subsystem folder. For details on the SPM groups, see Grouping
Host Bus Adapters.
