The output of this command shows the serial bus path (for example,
0000:81:00.1
) and the new MAC
address (for example,
90:e2:ba:7c:5a:fc
).
Tip:
As an alternative to the command above, you can use the command below to print only the
serial bus paths and MAC addresses in uppercase.
for add in `ls /sys/devices/pci*/*/*/net/*/address`; do echo -en
"`echo $add|sed 's/\// /g' | awk '{print $5}'`\t"; cat $add|tr 'a-f'
'A-F'; done
c) Fill in the serial bus path in ascending order in the
Serial Bus Path
column of the work table.
d) Fill in the MAC address corresponding to the serial bus path in ascending order in the
MAC Address on the
New Chassis
column of the work table.
For the sample output from the step above, the work table would look like this:
Serial Bus Path
MAC Address on the New
Chassis
Ethernet Port Name

0000:01:00.1

0000:81:00.0
90:e2:ba:7c:5a:fc

0000:81:00.1
90:e2:ba:7c:5a:fd
eth5
0000:82:00.0
90:e2:ba:7c:5d:a4
eth6
0000:82:00.1
90:e2:ba:7c:5d:a5

e) Close the SSH session to the Controller Node.
You are now back in the SSH session to the Management Node.
11.
Get the machine GUID and device GUID of the new chassis.
a) On the Management Node, start the Q-Shell:
/opt/qbase3/qshell
b) Create a cloudAPI connection.
cloudapi = i.config.cloudApiConnection.find('main')
c) Retrieve the machine GUID for the
new chassis
, using the value of
Temporary Hostname of Node
in
uppercase
, from the work table, for
hostname_of_new_node
in the command below:
machine_guid = cloudapi.machine.find(name='
hostname_of_new_node
')['result'][0]
