IBM 8677 Saving and restoring the configuration file

vIf you plan to use redundant management modules and want both to use the

same IP address, disable DHCP and configure and use the static IP address (the

IP configuration information will be transferred to the redundant management

module automatically when needed). Otherwise, configure the DHCP setting as

you prefer. Youneed to configure the static IP address only if DHCP is disabled.

–IP address - The IP address for the management module. The IP address

must contain four integers from 0 to 255, separated by periods, with no

spaces or consecutive periods. The default setting is 192.168.70.125.

–Subnet mask - The subnet mask must contain four integers from 0 to 255,

separated by periods, with no spaces. The default setting is 255.255.255.0

–Gateway address - The IP address for your network gateway router.The

gateway address must contain four integers from 0 to 255, separated by

periods, with no spaces.

Under MM Control, click Network Interfaces →Internal Network Interface (eth1).

This interface communicates with the network-interface I/O modules, such as the

Ethernet switch module or the Fibre Channel switch module.

vSpecify the IP address to use for this interface. The subnet mask must be the

same as the subnet mask in the external network interface (eth0).

vYoucan configure the locally-administered MAC address for this interface; the

other fields (data rate, duplex mode, maximum transmission unit (MTU), and

burned-in MAC address) are read-only.

Under I/O Module Tasks, click Management; then, click the bay number that

corresponds to the I/O module you are configuring.

vIn the New Static IP address fields, specify the IP address to use for this

interface. The subnet mask must be the same as the subnet mask in the internal

network interface (eth1).

vClick Advanced Management →Advanced setup. Enable the external ports and

external management.

Saving and restoring the configuration file

After you have configured the management module, you can save the configuration

file to a diskette or other external media. Then, if the configuration in the

management module becomes damaged or the management module is replaced,

you can restore the saved configuration file to the management module. Use the

management-module Web interface to save and restore the configuration file (MM

Control →Configuration File).

Note: If you cannot communicate with a replacement management module through

the Web interface or the IBM Director programs, the IP address might be

different from the IP address of the management module just removed.

Press the IP reset button to set the management module to the factory

default IP addresses; then, access the management module using the

factory IP address (see “Configuring the management module for remote

access” on page39 for the factory IP addresses) and configure the

management module or load the saved configuration file.
