of hardware failures.
Retrieve an SMU backup
Perform one of the following procedures to retrieve an SMU backup (listed below in easiest to
hardest order):
1. If the original SMU GUI is functional, use the private management switch to obtain an
SMU backup
2. If the original SMU GUI is NOT functional, either
a) Use an ssh session to retrieve a backup
OR
b) Use a USB stick to obtain an SMU backup.
If the original SMU GUI is functional, use the private management switch to obtain
an SMU backup
1. Connect your laptop to the private management switch.
a. Configure the laptop ip address:
i. IP address 192.0.2.150
ii. Netmask 255.255.255.0
2. Open a web browser, navigate to 192.0.2.1 and logon as Username: admin Password:
nasadmin
3. Back up the SMU.
a. In the GUI, navigate to Home > SMU Administration > SMU Backup and Restore
b. Click the Backup SMU: Backup button
c. Save the configuration file to a location on your computer
Note: If managing a cluster, leave the original SMU powered up and cabled to provide
quorum.
d. Verify that the archive file opens
Use an ssh session to retrieve a backup (if the original SMU GUI is NOT
functional)
If you can get to the SMU with an ssh session then you can retrieve a backup to copy the backup
files directly to your laptop.
1. Connect your laptop to the management switch.
2. Change the interface to 192.0.2.100
3. Open WinSCP.
a) File Protocol: scp

b) Hostname: 192.0.2.1
c) Username: manager
d) Password: nasadmin
e) Click Login.
f) Above the left pane, open the drop-down and navigate to the location where you
want to store the backup.
g) In the right pane, click .. multiple times to get to the root of the SMU file structure
a. Navigate through the file structure to /var/opt/smu/archive/smu-backup/<smu
public ip address>
h) You will find multiple backup .zip files.
i) Click and drag them to the left pane.
j) Click OK to start the copy.
4. You now have the backup files on your laptop.
Use a USB stick to obtain an SMU backup (if the original SMU GUI is NOT
functional)
