alarms, and so on) associated with external enclosures. Physical disks can be contained in an enclosure or attached to the backplane of a system.

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 hot plug enclosures. Hot plugging is defined as adding of a component to a system while the operating system is still running.

The physical devices connected to the controller must have the latest firmware. For the latest supported firmware, contact your service provider.

Storage events from PERC are mapped to SNMP traps and WSMAN events as applicable. Any changes to the storage configurations are logged in the Lifecycle Log.
