If you need to replace this module, see FRU Replacement Time Limit (
) for more details.
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.
