Installing Software Maintenance Update on Cisco DCNM 11.4(1) to use Network Insights for Resources Application
After installing Cisco DCNM, you can download and install various applications from the Cisco App Center. In Cisco DCNM 11.4(1) LAN Fabric installation, to use Network Insights for Resources (NIR) Release 2.2.2 or later, install the latest software maintenance update. For a Cisco DCNM Native HA clustered deployment, apply the update on the Active and Standby nodes only. You need not update the Compute nodes.
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 |
Cisco DCNM allows you to upload the NIR 2.2.2 application without the maintenance update. However, you cannot start the application. An error appears asking you to install the maintenance update (patch) before using the NIR 2.2.2 application. |
Note |
Only a root user must install the maintenance update (patch) on the Cisco DCNM 11.4(1). |
To apply the maintenance update to use NIR 2.2.2 application with Cisco DCNM LAN Fabric installation in Native HA mode, perform the following steps:
Before you begin
-
Ensure that both the Cisco DCNM 11.4.1(1) Active and Standby peers are up and running.
-
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
Procedure
Step 1 |
Download the maintenance update (patch). |

Step 2 |
Unzip the dcnm-va.11.4.1-p1.iso.zip file and upload the file to the /root/ folder in both Active and Standby node 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 6 |
On the Standby node, apply the patch. |

Log on to the DCNM Web UI with appropriate credentials.
Choose Applications > Catalog. Verify the version of the Compliance application. It must show the version as 4.0.1 after successfully installing the maintenance update on Cisco DCNM 11.4(1).
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 NIR 2.2.2 application on the Cisco DCNM Web UI. Refer to Installing and Deploying Applications for instructions.
