IBM TotalStorage DS4800, Инструкция по установке, эксплуатации и обслуживанию

If the auto-negotiation process fails, the controllers will consider the link to
be down until negotiation is again attempted at one of these points in time.
For a 4 Gbps controller, the supported host-channel link speeds are 1, 2,
and 4 Gbps.
Ethernet ports
The Ethernet connections provide for out-of-band management
configurations to a host. The Ethernet ports are used for an RJ-45
10BASE-T or 100BASE-T Ethernet connection to each controller. Use the
Ethernet connection to directly manage the DS4800.
Use one Ethernet port for daily management of the DS4800. Reserve the
other port for use by service personnel or for subsystem monitoring
hardware that may be available in the future.
The two Ethernet ports must be connected into networks with two separate
subnet masks. Otherwise, the following Recovery Guru error will be
generated:
Ethernet Configuration conflict. Both Ethernet ports for a given DS4800
controller have been assigned IP addresses from the same subnet.
You can also make out-of-band management connections to the DS4800
controllers using the default IP addresses. The default IP addresses for the
controller A Ethernet ports 1 and 2 are 192.168.128.101 and
192.168.129.101, respectively. The default IP addresses for the controller B
Ethernet ports 1 and 2 are 192.168.128.102 and 192.168.129.102,
respectively. The default subnet mask for all four Ethernet ports is
255.255.255.0. See “Setting up IP addresses for DS4000 storage
controllers” for more information.
RS-232 serial port
The RS-232 serial connection provides a diagnostic port for use by service
personnel only to perform diagnostic operations on the RAID controllers.
Attention: Incorrect use of the serial port can result in loss of data access
and, in some cases, in loss of data. Do not make any connections to the
serial port unless you do so under the direct guidance of IBM support
personnel.
Note: The maximum baud rate is 115 200 bps. The default baud rate
setting from the factory is 38 400 bps.
Setting up IP addresses for DS4000 storage controllers
After you install DS4000 Storage Manager (as described in the DS4000 Storage
Manager Installation and Support Guide for your host operating system), complete
one of the following procedures to set up IP addresses:
v
“Steps for setting up the DHCP/BOOTP server and network”
v “Steps for assigning static TCP/IP addresses to the DS4000 controllers” on page
15
Steps for setting up the DHCP/BOOTP server and network: To complete this
procedure, you must have the following components:
v A DHCP or BOOTP server
v A network management station (NMS) for Simple Network Management Protocol
(SNMP) traps
v
A host that is connected to a storage subsystem through a fibre-channel I/O path
