• The command-line interface (CLI) enables you to interact with the storage system using command
syntax entered via the keyboard or scripting.
Refer to the
QXS G2 CLI Reference Guide
for additional information.
CNC Ports Used for Host Connection
QXS G2 systems that use CNC technology allow you to select the desired host interface protocol from
the available Fibre Channel (FC) or Internet SCSI (iSCSI) host interface protocols supported by the
system.
NOTE: Refer to SFP Option for CNC Ports for additional information.
You can use the CLI to set all controller host ports to use either FC or iSCSI protocol using the
set
host-port-mode
CLI command. The QXS G2 systems support the following link speeds:
• 16Gb FC
• 8Gb FC
• 10GbE iSCSI
• 1GbE iSCSI
Alternatively, for QXS G2 systems you can use the CLI to set CNC ports to support a combination of
host interface protocols. When configuring a combination of host interface protocols, host ports 0
and 1 are set to FC (either both 16Gb/s or both 8Gb/s), and host ports 2 and 3 must be set to iSCSI
(either both 10GbE or both 1Gb/s), provided the CNC ports use qualified SFP connectors and cables
required for supporting the selected host interface protocol.
NOTE: Refer to the
QXS G2 CLI Reference Guide
for additional information.
CNC controller modules ship with CNC ports initially configured for FC. When connecting CNC ports
to iSCSI hosts, you must use the CLI (not the disk management utility/GUI) to specify which ports will
use iSCSI. It is best to configure the ports before inserting the iSCSI SFPs into the CNC ports.
Intended audience
This guide is intended for storage customers and technicians.
NOTE: This guide provides information for initial hardware setup, and removal and installation of
CRUs for the QXS G2 systems (RAID chassis and expansion chassis).
