Software Maintenance Update (SMU) version 11.5(2) on Cisco DCNM 11.5(1) to use Network Insights Applications
Cisco DCNM Release 11.5(2) offers a Software Maintenance Update (SMU) that can be applied only on top of the DCNM Release 11.5(1) for the OVA/ISO/Appliance form factor. The DCNM LAN Fabric 11.5(2) release is the first release version that supports Cisco Nexus Insights, Release 5.1 or higher, with Cisco Nexus Dashboard, Release 2.0.2 or higher.
After installing Cisco DCNM, you can download and install various applications from the Cisco App Center.
To download, add, start, stop, and delete applications from the Cisco DCNM Web UI, choose Applications > Catalog > Browse App Center. Refer to Installing and Deploying Applications for instructions.
Note |
SMU version 11.5(2) is supported with Cisco DCNM Release 11.5(1) only. |
Cisco DCNM allows you to upload the NI 5.1 application without the maintenance update. However, you cannot start the application. An error appears asking you to install the SMU before using the NI 5.1 applications.

Installing SMU version 11.5(2) on Cisco DCNM 11.5(1) Standalone Deployment
To apply the Software Maintenance Update (SMU) on Cisco DCNM LAN Fabric installation in Standalone deployment mode, perform the following steps:
Before you begin
-
Ensure that Cisco DCNM 11.5.(1) appliance is operational.
-
Take a backup of the application data using the appmgr backup command.
dcnm# appmgr backup
Copy the backup file to a safe location outside the DCNM server.
-
If Cisco DCNM appliance is installed in VMware environment, ensure that you take a snapshot of the virtual machine. For instructions, refer to VMware Snapshot Support for Cisco DCNM.
-
Ensure that you plan for a maintenance window to install SMU version 11.5(2).
Procedure
Step 1 |
Download the SMU file. |
||
Step 2 |
Unzip the dcnm-va-patch.11.5.2.iso.zip file and upload the file to the /root/ folder of the DCNM setup. |
||
Step 3 |
Log on to the Cisco DCNM appliance using SSH as a sysadmin user. Run the su command to enable root user.
|
||
Step 4 |
Run the following command to create a screen session.
This creates a session which allows you to execute the commands. The commands continue to run even when the window is not visible or if you get disconnected. |
||
Step 5 |
Create a folder named iso using the mkdir -p /mnt/iso command.
|
||
Step 6 |
Mount the DCNM SMU version 11.5(2) file in the /mnt/iso folder.
|
||
Step 7 |
Navigate to /scripts/ directory.
|
||
Step 8 |
Run the ./inline-upgrade.sh script.
|
||
Step 9 |
Ensure the DCNM application is functional, by using the appmgr status all command.
|
||
Step 10 |
Terminate the screen session, by using the exit command.
|
||
Step 11 |
Unmount the dcnm-va-patch.11.5.2.iso file from the DCNM setup.
|
What to do next
Log on to the DCNM Web UI with appropriate credentials. The version shows 11.5(2) on the login screen.
Note |
If you try to install the maintenance update again, a note appears stating that the patch is already applied on the Cisco DCNM. |
You can now start the NI 5.1 applications on the Cisco DCNM Web UI. Refer to Installing and Deploying Applications for instructions.
Installing SMU version 11.5(2) on Cisco DCNM 11.5(1) Native HA Deployment
To apply the Software Maintenance Update (SMU) on Cisco DCNM LAN Fabric installation in Native HA deployment mode, perform the following steps:
Before you begin
-
Ensure that both the Cisco DCNM 11.5.(1) Active and Standby peers are up and running.
To apply this software maintenance update on Cisco DCNM Virtual Appliance in Native HA Mode, apply this update on the Active appliance. Wait until the role of the Active appliance is Active again. Apply the update on the Standby appliance, later.
-
Check and ensure that the Active and Standby servers are operational, using the appmgr show ha-role command.
Example:
On the Active node: dcnm1# appmgr show ha-role Native HA enabled. Deployed role: Active Current role: Active
On the Standby node: dcnm2# appmgr show ha-role Native HA enabled. Deployed role: Standby Current role: Standby
-
Take a backup of the application data using the appmgr backup command on both Active and Standby appliances.
dcnm1# appmgr backup
dcnm2# appmgr backup
Copy the backup file to a safe location outside the DCNM server.
-
If Cisco DCNM appliance is installed in VMware environment, ensure that you take a snapshot of the virtual machine. For instructions, refer to VMware Snapshot Support for Cisco DCNM.
-
Ensure that you plan for a maintenance window to install SMU version 11.5(2).
