Identifying a storage array performance problem
Continuing from the previous example, “Identifying a host performance problem” on
page 59, this example demonstrates how the UNIX administrator now analyzes the
data collected on 3/31/06 to determine what caused the performance problems the
sales department experienced at two peak periods (9 A.M. and 6 P.M.)
Accessing the host
The UNIX administrator opens the Repository holding the performance data collected
for host l82ar156 and Symmetrix 000187400075.
To complete this task, the UNIX administrator:
1. On the menu bar, from the File menu, selects Open.
The Data Selection dialog box appears.
2. Under Data Provider, from the Class pull-down menu, selects Host.
3. From the Identifier pull-down menu, selects host l82ar156.
4. Under Archives, selects the radio button next to Daily.
5. Under Daily, selects 3/31/06.
6. Clicks OK.
The Performance Manager console appears with host l82ar156 in the Views pane.
Analyzing the host device
The UNIX administrator now analyzes host device c2t0d2s2 (the device host l82ar156
uses to connect to the Symmetrix) for the performance problems. The DBA provides
the name of the host device.
To complete this task, the UNIX administrator:
1. Clicks the Metrics tab to switch to the Metrics panes.
2. In the top Metrics pane, under the folder for host l82ar156, selects the Physical
Device folder.
3. The devices for the host and the Symmetrix appear in the middle Metrics pane.
4. In the middle Metrics pane, selects device c2t0d2s2.
