Enclosure management

IOMs actively manage the enclosure. Each module has a SAS expander with its own storage enclosure processor
(SEP) that provides a SCSI Enclosure Services (SES) target for a host to interface to through the ANSI SES
Standard. If one of these modules fails, the other module will continue to operate.
Refer to a module's specification or the SES Interface specification for definitions of the module's functions and its
SES control.
The storage system also provides a command-line interface (CLI).

Command-line interface

The command-line interface can be accessed in the following ways:
• Serial port connection
• Ethernet Telnet connection
• Ethernet WBCLI utility
• SESCLI utility
The CLI utilities and capabilities are described in the GEM Command-line Interface document. Contact your
account manager for additional information.
