16. Verify fencing.
Note These steps verify Brocade Fibre Channel fencing only.
Before performing these steps, make sure you are not logged into the switch through
Telnet. If you are logged in, the brocade fencing script will fails with an error similar to
the following:
/sbin/fence_brocade -a ip_addr -l username -n 2 -p password -o disable
pattern match read eof at ./fence_brocade line 138
# echo $?
255
where ip_addr, username, and password is that of the Fibre Channel switch. Consult your
SAN administrator for this information.
To verify the fencing method, enter the following commands:
/sbin/fence_brocade -a ip_addr -l username -n 2 -p password -o disable
/sbin/fence_brocade -a ip_addr -l username -n 2 -p password -o enable
17. Complete the following steps to configure fencing from luci:
a. From the luci web interface, select the node.
b. Select choose a task...
c. Select fence this node.
