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

The following example is for a Linux system.


Note the disk size of the analytics cluster nodes. When adding disk, you must maintain uniform size across analytics cluster nodes.


  1. Add a new disk to the system, and partition and format the disk as needed.
  2. Use the vRealize Operations Manager administration interface to take the cluster offline.
  3. Stop the vmware-casa service.
  4. Move the contents of /storage/db into a directory on the new disk.
  5. Create a symbolic link from the new directory back to /storage/db, so that /storage/db now references the new disk.
  6. Start the vmware-casa service.
  7. Bring the cluster online.
