NOTE: It might take around 10 minutes for the virtual appliance clocks to synchronize with the NTP server.
Configuring deployment mode
Ensure that the following system requirements for the desired deployment modes are met:
Table 2. System requirements for deployment modes
Deployment modes Number of hosts Number of CPUs Memory—in GB
Small up to 250 2 8
Medium up to 500 4 16
Large up to 1000 8 32
NOTE: For any of the mentioned deployment modes, ensure that you reserve sufficient amount of memory resources to
the OMIVV virtual appliance by using reservations. See vSphere Documentation for steps about reserving memory
resources.
You can select an appropriate deployment mode to scale OMIVV to match the number of nodes in your environment.
1. In the APPLIANCE MANAGEMENT page, scroll down to Deployment Mode.
The configuration values of the deployment mode such as Small, Medium, or Large is displayed and by default, the deployment
mode is set to Small.
2. Click Edit if you want to update the deployment mode based on the environment.
3. In the Edit mode, select the desired deployment mode after ensuring that the prerequisites are met.
4. Click Apply.
The allocated CPU and memory are verified against the required CPU and memory for the set deployment mode and either of the
following situations happen:
• If the verification fails, an error message is displayed.
• If the verification is successful, the OMIVV appliance restarts and the deployment mode is changed after you confirm the change.
• If the required deployment mode is already set, a message is displayed.
5. If the deployment mode is changed, confirm the changes, and then proceed with rebooting the OMIVV appliance to allow the
deployment mode to be updated.
NOTE:
During the OMIVV appliance boot up, the allocated system resource is verified against the set deployment mode.
If the allocated system resources are less than the set deployment mode, the OMIVV appliance does not boot up to the
login screen. To boot up the OMIVV appliance, shut down the OMIVV appliance, update the system resources to the
existing set deployment mode, and follow the Downgrade deployment mode task.
Downgrading deployment mode
1. Log in to the Administration Console.
2. Change the deployment mode to the desired level.
3. Shut down the OMIVV appliance and change the system resources to the desired level.
4. Power on the OMIVV appliance.
Generating Certificate Signing Request
Ensure that you upload the certificate before registering OMIVV with the vCenter.
Generating a new Certificate Signing Request (CSR) prevents certificates that were created with the previously generated CSR from
being uploaded to the appliance. To generate a CSR, do the following:
1. In the APPLIANCE MANAGEMENT page, click Generate Certificate Signing Request in the HTTPS CERTIFICATES area.
A message is displayed stating that if a new request is generated, certificates created using the previous CSR can no longer be
uploaded to the appliance. To continue with the request, click Continue, or to cancel, click Cancel.
2. If you continue with the request, in the GENERATE CERTIFICATE SIGNING REQUEST dialog box, enter the Common Name,
Organizational Name, Organizational Unit, Locality, State Name, Country, and Email for the request. Click Continue.
3. Click Download, and then save the resulting certificate request to an accessible location.
