Original IP Address of Node
.
The Linux prompt appears.
b) At the Linux prompt, run the following command:
reboot

Controller Nodes
.
A list of Controller Nodes appears in the CMC.
b) Click the Controller Node whose chassis you have just replaced.
Identify the correct Controller Node by its hostname: it now matches the
Original Hostname of Node
value
you recorded in the worktable. This value is typically of the format
SystemID
-DC
nn
-R
nn
-CN
nn
.
c) Identify the IP addresses listed in the
Private IP

d) Open an SSH session to the Controller Node, using any one of the IP addresses you obtained from substep c,
and exit the OSMI menu.
The Linux prompt appears.
e) At the Linux prompt on the Controller Node, open the file
/opt/qbase3/cfg/qconfig/main.cfg
with
your text editor.
The file has a section that looks like this:
[main]
lastlogcleanup = 1428960577
domain = somewhere.com
nodetype = CPUNODE
nodename = 90E2BA7EB831
logserver_loglevel = 6
logserver_port = 9998
logserver_ip = 127.0.0.1
qshell_firstrun = False
machineguid = fc635662-5247-45b1-ab66-d0abe8e60712
f) Replace the value after
nodename =
with the new MAC address from your work table, under
MAC Address
of Node
.
Note:
The MAC address must be
in uppercase and without colons
. For example,
00:25:90:3B:C1:72
must be typed as
0025903BC172
.
g) Save and close the configuration file.
h) Start the Q-Shell.
