Important notes:
- You cannot scale down a vRealize Operations Manager node.
- All Analytic nodes must match in vCPU, RAM, and Disk.
- Stay within the supported sizing guidelines for your version.
- After resizing Analytic nodes, review remote collector sizes and consider the number of collecting objects per node to see if the remote collector size can, or needs to be increased.
To resize a vRealize Operations Manager node, follow the steps below.
- Log in to vRealize Operations Manager admin UI as the local admin user.
Example: https://IP_or_FQDN/admin
Note: Replace IP_or_FQDN with the actual IP or FQDN of vRealize Operations Manager UI.
- Click Take Offline under Cluster Status.
Note: Wait for Cluster Status to show as Offline.
- As an administrator, navigate to the node you want to scale up in the vSphere Web UI.
- Right-Click on the node and select Power > Shut Down Guest OS.
- Once the node is powered off, ensure the Virtual Hardware version is upgraded to the latest version:
- Right-Click the node and click Compatibility > Upgrade VM Compatibility.
- Read the warning and click Yes.
- In the Compatible with box, select the desired compatibility level and click OK.
- Right-click on the node and select Edit Settings.
- Edit the CPU and/or Memory to the desired level, based on the vRealize Operations Manager Sizing Guidelines.
- Click OK.
- If the node selected in step 3 was an Analytic node, repeat steps 4-8 on all other Analytic nodes so their resources match.
- Right-click the node(s) and select Power > Power On.
- Once all nodes have powered back on, navigate back to the vRealize Operations Manager admin UI (https://IP_or_FQDN/admin) as the local admin user.
- Click Bring Online under Cluster Status.
