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:
l "Thermal Shutdown for Enclosures"
l "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:
l To see new disks attached to the controller.
l To make the operating system recognize a virtual disk.
l To make Storage Management display a new virtual disk.
l After expanding a virtual disk, you may need to rescan the controller so that the virtual disk can use the additional disk space.
l To update the status of an offline disk.
l To display updated information in a clustered configuration after a failover of cluster resources.

l "Time Delay in Displaying Configuration Changes"
Time Delay in Displaying Configuration Changes
When you change the storage configuration, the Storage Management MIB (Management Information Base) is updated to reflect storage configuration
changes. However, it may take up to five minutes to update the MIB with the most recent storage configuration. For this reason, there is a time delay of up to
five minutes between the receipt of the trap and the ability to identify the configuration changes by querying the Storage Management MIB. This time delay is
particularly notable when creating a new virtual disk or performing an unmirror or split mirror on a RAID 1-concatenated virtual disk. You can minimize this time
delay by performing a controller rescan. See "Rescan Controller" for more information.
