Following the upgrade of DFM from version 5.2.0 to 5.2.1 I started to see a warning in the onCommand Management console that the NetApp DataFabric Manager had expired and to create a new one.

Surprisingly the cert had expired ages ago but neither I nor anyone else noticed. The first step in fixing the issue was to check the SSL service details to find the expiry date of the current certificate. To find this open a command prompt and run the command:

dfm ssl service detail

If the cert is not valid after the current date, or in my case after Dec 9 2015 then a new one needs to be created.

The steps to create a new certificate are:

dfm ssl server setup
KeySize: 2048
Country Name: AU (or whatever two letter country code suites your needs)
State or Province: <insert your state name>
Locality Name: <insert your city>
Organization Name: <insert company name>
Common Name: <insert FQDN of your DFM server>
Email Address: <insert your address>

Once the cert has been created you’ll be prompted to restart the http services.

Once you restart the services you can acknowledge the alert in onCommand Manager and the alert will be gone
