Monitoring MD3600i Series System Performance
You can use the Performance Monitor to select virtual disks and RAID
controller modules to monitor or to change the polling interval.
Keep the following guidelines in mind when using the Performance Monitor:
• The Performance Monitor does not dynamically update its display if any
configuration changes occur while the window is open. You must close the
Performance Monitor window and reopen it for the changes to be
displayed.
• Using the Performance Monitor to retrieve performance data can affect
the normal storage array performance depending on the polling interval
that you set.
• If the storage array you are monitoring begins in or transitions to an
unresponsive state, an informational dialog is displayed. The dialog
informs you that the Performance Monitor cannot poll the storage array
for performance data.
To monitor the performance of the arrays:
1 Open MDSM and select the appropriate storage array.
2 Open the Array Management Window (AMW) for the selected storage
array.
3 In the AMW, select Storage Array Monitor Performance.
4 Click Settings.
a Select the items that you want to monitor.
You can monitor:
• RAID Controller modules
• Virtual disks
• Storage array totals
NOTE: By default, all items are selected.
b In Polling interval, select how often you want to update the
performance statistics.
NOTE: For an accurate elapsed time, do not use the Set RAID Controller
Module Clocks option while using the Performance Monitor.
