Using Enclosure Temperature Probes
Physical disk enclosures have temperature probes that warn you when the
enclosure has exceeded an acceptable temperature range. For more
information on using temperature probes, see the following:
• SMART Thermal Shutdown
• Set Temperature Probe Values
Rescan to Update Storage Configuration Changes
The Rescan task scans the storage attached to the controller’s connectors
(channels or ports) to verify the currently connected devices or to recognize
devices that have been added to or removed from the connectors. When you
do a rescan on a controller object, all storage attached to the controller is
rescanned. Performing a rescan causes the controller to recognize changes in
the storage configuration, such as adding or removing physical disks from a
virtual disk or changing a RAID level.
You may want to rescan in the following situations:
• To see new disks attached to the controller.
• To make the operating system recognize a virtual disk.
• To make Storage Management display a new virtual disk.
• After expanding a virtual disk, you may need to rescan the controller so
that the virtual disk can use the additional disk space.
• To update the status of an offline disk.
• To display updated information in a clustered configuration after a failover
of cluster resources.
NOTE: For SCSI controller-based systems, if you want to rescan all controllers,
perform the procedure in Global Rescan. If you want to rescan only the components
attached to a particular controller, perform the procedure in Rescan Controller.
NOTE: Clicking the Refresh button in the right pane refreshes only the right pane.
To view the new physical disk in the left pane tree view, click the system name
displayed at the top of the left pane, or select ViewRefresh from the browser’s
menu bar.
