Configuring the Partner Group
A partner group provides redundant management communications for its two
arrays. If one array controller fails, the other controller assumes control of all
management reporting as well as, if possible, data access to the failed array’s disk
drives. To enable this redundant management reporting, you must configure the
partner group.
Configuring a partner group is a two-step process. First, through a serial connection,
you configure the partner group’s IP connectivity so that you can connect to it
through the Ethernet. Second, through the Ethernet, add the server’s IP address into
the partner group’s
syslog.conf
files so that messages and warnings generated
by the partner group can be reported to a system administrator.
Adding the Partner Group’s IP Settings
Repeat this entire procedure for the MCU of each partner group installed, but not for
its alternate MCU.

To Add the IP Settings
The partner groups are connected to a local area network (LAN) as shown in
on page 9. To set up the connectivity for a partner group, see your network
administrator to get the IP addresses you need and perform the following steps.
1. Connect a terminal to the COM port (see
on page 7) on the back of the
MCU array.
A Tip kit was supplied with your Sun StorEdge N8400 filer that includes a 9-pin to
25-pin adapter, a 9 pin Tip adapter, and an interconnect cable.
■
If you are using a Sun workstation, connect either TTYA or TTYB to the array’s
COM port using the Tip kit.
■
If you are using a PC, connect either of the serial ports of the PC to the array’s
COM port using the Tip kit.
2. From your terminal, open a session with the array:
■
If your terminal is a PC, open a hyperterminal session with these communications
settings: 8 bit, no parity, 1 stop bit, 9600 baud, Xon/Xoff.
■
If your terminal is a Sun workstation, open a Tip session with these
communications settings: 8 bit, no parity, 1 stop bit, 9600 baud, Xon/Xoff.
