Enclosures
Storage Management enables management of various enclosures and their components. In addition to managing the physical disks
contained in the enclosure, you can monitor the status of the fans, power supply, and temperature probes in an enclosure. You can view
these components by expanding the controller, connector, and enclosure objects in the Storage Management tree view.
Storage management allows hot plugging of enclosures. Hot plugging is defined as the adding of a component to a system while the
operating system is still running.
NOTE: This feature requires that the physical devices connected to the controller have the latest firmware. For the
latest supported firmware, contact your service provider.
After you hot plug or hot reconfigure an enclosure, refresh the left tree to display the change in status and configuration; a system reboot
is not required.
NOTE: Storage Management does not allow hot removal of enclosures. Reboot the system to effect this change in
Storage Management.
Storage Management notifies you of enclosure status changes through alerts that are displayed in the Alert Log.
