Managing Enclosures Each controller module and expansion module contains an Expander Controller (EC). The storage system can query EC for information about enclosure environmental conditions such as temperature, power supply and fan status, and the presence or absence of disk drives. The system can also communicate information to the EC about RAID activities such as disk drive rebuilds and failed disk drives. The EC is also referred to as the enclosure management processor (EMP). Displaying Enclosure Status You can view enclosure status information from the following SMU pages: ■ Monitor > Status > Enclosure Status. See "Enclosure Status" on page 161 for more information. ■ Monitor > Status > Module Status. See "Module Status" on page 159 for more information. ■ Manage > General Config > Enclosure Management. See "Using Enclosure Management Pages" on page 142. ■ System Panel at the bottom of every page. See "System Panel" on page 26 for more information.
