Displaying and Editing the Routing Table

The ROUTE command displays the current routing table of the system (Figure 3–20

)

and allows the

administrator to change it. The routing table describes how the controller can communicate with the
hosts on other networks.

Figure 3–20

Routing Table

ROUTE ADD= GATEWAY= adds gateways to the routing
table. Up to 6 permanent routes can be added to the tables. For example, to indicate that the machine with
Internet address 91.0.0.3 is the gateway to the destination network 90.0.0.0, enter: ROUTE
ADD=90.0.0.0 GATEWAY=91.0.0.3

ROUTE DEL= GATEWAY= deletes gateways from the routing
table.

ROUTE GATEWAY= sets the current gateway in the network routing table to the
specified Internet address. The gateway is where IP datagrams are routed when there is no specific
routing table entry available for the destination IP network or host. If an empty gateway value is
provided, then the current gateway is cleared.

Restarting the Controller

3.2.5.1

System Restart

RESTART performs a restart on the controller on which the command is issued. This command prepares
the system to be restarted. The system halts all I/O requests and saves the data to the disks before
restarting. The restart process may take several minutes to complete.

NOTE : If cache coherency is enabled, restarting a controller unit will cause the partner

controller to fail the restarting unit. Once the reboot is complete, you will have to heal
the controller unit.

RESTART DELAY=X (where “X” is minutes) delays a restart of a unit between 0 and 255 minutes.
