Using Enclosure Temperature Probes
Physical disk enclosures have temperature probes that warn you when the enclosure has exceeded an
acceptable temperature range.

Rescanning To Update Storage Configuration Changes
The Rescan task scans the storage device attached to the connectors on the controller (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, rescan a controller object, all storage devices attached to the
controller are 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 can rescan a controller object to:
• View new disks attached to the controller.
• Enable the operating system to recognize a virtual disk.
• Enable Storage Management to display a new virtual disk.
• Allow the virtual disk to use the additional space after is it expanded.
• Update the status of an offline disk.
• Update information in a clustered configuration after a failover of cluster resources.
NOTE: To view the new physical disk, click the system name displayed at the top of the left
pane, or select View → Refresh from the menu bar on the browser.

Time Delay In Displaying Configuration Changes
When you change the storage configuration, Storage Management quickly generates SNMP traps in
response to the configuration changes. The Storage Management, Management Information Base (MIB) is
also 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 an SNMP 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.
