F.2 Managing Enclosures
An enclosure management processor (EMP) is a device in the enclosure from which the X24 Subsystem
can inquire about the enclosure’s environmental conditions such as temperature, power supply and fan
status, and the presence or absence of disk drives. The X24 Subsystem can also tell the EMP about RAID
activities such as drive rebuilds and failed disk drives.
If you have only one EMP, the configuration settings are automatically enabled when the X24 Subsystem
is installed. No changes are required to the default configuration settings to support EMP.
If you have more than one EMP, you must set up the EMP LUNs as described in the next section.
