You add to the data disk of vRealize Operations Manager vApp nodes when space for storing the collected data runs low.


  • Note the disk size of the analytics cluster nodes. When adding disk, you must maintain uniform size across analytics cluster nodes.
  • Use the vRealize Operations Manager administration interface to take the node offline.
  • Verify that you are connected to a vCenter Server system with a vSphere Client, and log in to the vSphere Client.


  1. Shut down the virtual machine for the node.
  2. Edit the hardware settings of the virtual machine, and add another disk.
    Note: Do not expand disks. vRealize Operations Manager does not support expanding disks.
  3. Power on the virtual machine for the node.


During the power-on process, the virtual machine expands the vRealize Operations Manager data partition.
