Maint (maintenance
module) ports Maintenance
module Use these two ports to connect directly to the
maintenance module.
Management ports Modules 1, 2,
3 Use these three redundant ports to connect to systems
that are used for managing the XIV system using the
IBM XIV Storage Management GUI and IBM XIV
command-line interface (XCLI). These ports can also be
used for sending email notifications and SNMP traps
about event alerts, and communication with key servers
for managing encryption keys.
Note:
Use all three connections for redundancy. If the
customer uses only one path and the module for that
connection goes down, the ability to manage the XIV
system is lost.
For information about IP configuration and protocol
requirements, see “Management ports requirements” on
page 53.
VPN (remote support)
ports Modules 1, 3 Use these two virtual private network (VPN) ports are
used to connect to the XIV Remote Support Center.
Note:
Use both VPN connections for redundancy to
avoid losing remote support if one of the modules fails.
Tech (technician) ports (Model
281x-11x
only)
Modules 2, 4
(Models
281x-21x and
281x-314
only)
Modules 2, 3
Use these two ports to connect the XIV system directly
to a notebook computer on which the GUI and XCLI are
installed. The IBM service representative uses these
ports to initial configure and service the XIV system.
A Dynamic Host Configuration Protocol (DHCP) server
is implemented over this port. The DHCP server
automatically assigns IP addresses to the notebook
computer and establishes a connection to the XIV
system.
To establish a connection between the notebook
computer and the XIV system, you must manually set
the Ethernet adapter on the notebook computer to use a
fixed address and subnet mask. Do not use the Dynamic
Host Configuration Protocol (DHCP) server that is
implemented over this port.
Important:
v The technician port must be used only by an IBM
service representative. It is not intended for customer
use.
v Use the technician ports only for a direct-connection
to a single notebook-computer. Do not connect the
technician ports to the network. A connection to the
network might cause incorrect IP address assignments
to the host systems.
v The technician port for module 4 is active on XIV
system code V11.0.1 or later. The port is not active on
XIV system code V11.0.0.
v (Model 218x-11x only) The technician port that is
labeled "3" is logically routed to module 3 through
module 4.
Modem port Modem Use this port to connect to a modem for remote support.
Note:
The modem is no longer supported as part of the
rack configuration for Indonesia and Brazil. For more
information, contact your IBM planning representative.
