Connecting hosts
IP address scheme for the controller pair — four iSCSI ports per controller
When all CNC ports are configured for iSCSI, the scheme is similar to the one described for two-ports
above. See
Controller enclosure — rear panel layout
on page 15 for iSCSI port numbering.
For example (with a netmask of 255.255.255.0):
•
Controller A port 0: 10.10.10.100
•
Controller A port 1: 10.11.10.120
•
Controller A port 2: 10.10.10.110
•
Controller A port 3: 10.11.10.130
•
Controller B port 0: 10.10.10.140
•
Controller B port 1: 10.11.10.150
•
Controller B port 2: 10.10.10.160
•
Controller B port 3: 10.11.10.170
In addition to setting the port-specific options described above, you can view settings using the GUI.
If using the SMC, in the
System
topic, select
Action
>
Set Up Host Ports
.
The Host Ports Settings panel opens, allowing you to access host connection settings.
Connecting a management host on the network
The management host directly manages storage systems out-of-band over an Ethernet network.
1.
Connect an RJ-45 Ethernet cable to the network port on each controller.
2.
Connect the other end of each Ethernet cable to a network that your management host can access
(preferably on the same subnet).
NOTE:
Connections to this device must be made with shielded cables—grounded at both ends—with
metallic RFI/EMI connector hoods, in order to maintain compliance with FCC Rules and Regulations. See the
Product Regulatory Compliance and Safety document.
Updating firmware
After installing the hardware and powering on the storage system components for the first time, verify that
the controller modules, expansion modules, and disk drives are using the current firmware release.
Using the Storage Management Console, in the
System
topic, select
Action
>
Update Firmware
.
The Update Firmware panel opens. The Update Controller Module tab shows versions of firmware
components currently installed in each controller.
NOTE:
The SMC does
not
provide a check-box for enabling or disabling Partner Firmware Update for
the partner controller. To enable or disable the setting, use the
set advanced-settings
command, and set the
partner-firmware-upgrade
parameter. See the CLI Reference Guide
for more information about command parameter syntax.
Optionally, you can update firmware using FTP (File Transfer Protocol) as described in the Storage
Manager Guide.
IMPORTANT:
See the “Updating firmware” topic in the Storage Manager Guide
before performing a
firmware update. Partner Firmware Update (PFU) is enabled by default on S3200/S2200 systems.
