Refreshing the storage subsystem list
SAN Connection Manager provides the ability to quickly refresh a subsystem on your SAN. Refreshing the
subsystem list shows the most current topology of your SAN in the Physical Connection and LUN
Assignment maps. It also discovers any status change in the subsystem’s drives, controllers, and logical
disks.
To refresh the storage subsystem list:
1. On the Advanced Operations menu, click Refresh the Storage Subsystem List.
A message box states the refresh will delete all existing data and rebuild the list, and asks if you want
to continue.
IMPORTANT: Refreshing the subsystem could take a while depending on the number of
subsystems, each subsystem’s IO traffic, and its number of drives and logical disks.
2. To continue, click Yes.
Changing the discovery refresh intervals
SAN Connection Manager automatically polls system components (host, switch, storage device) for the
most current information to display. You can configure how often each system component is polled using
the Change Discovery Refresh Interval option. System components are polled only when SCM is not
running. The minimum value is determined dynamically upon each discovery. SCM will check to ensure
you don’t go below the minimum. The maximum value is one week.
To configure the discovery refresh intervals:
1. On the Advanced Operations menu, click Change Discovery Refresh Interval.
Figure 97 Discovery Refresh Intervals dialog box
2. On the Discovery Refresh Intervals dialog box, choose one of the following:
• Click the up or down arrows next to the text box to change the number of minutes.
• Type the number of minutes in the text box.
3. Click OK to save the changes.
