Before you upgrade, you must increase hardware resources for each VMware vRealize ™ Automation appliance.

About this task

If you have taken a snapshot of each vRealize Automation appliance, you must clone each appliance and increase the hardware resources on each clone. Ensure that you have at least 60 GB of free space on each appliance in your VMware vCenter Server ™. After you clone your appliances, power off the original appliances before you perform this procedure on each appliance clone.

These steps are based on the Windows client.


  1. Log in to vCenter Server.
  2. Right-click the cloned vRealize Automation appliance icon and select Edit Settings.
  3. If there is an existing virtual Disk 4 from a previous vRealize Automation 6.2.x release, perform the following steps. If you do not have an existing virtual Disk 4, go to step 4.
    1. Power on the virtual machine.
    2. Open a new command prompt and navigate to the /etc/fstab.
    3. Open the fstab file, and remove lines starting with /dev/sdd that contain the Wal_Archive write ahead logs.
    4. Save the file.
    5. Power off the virtual machine.
    6. Right-click the cloned vRealize Automation appliance icon and select Edit Settings.
    7. Delete Disk 4 on the cloned virtual machine and create Disk 4 with a disk size of 50 GB.

      If you have two disks, add Disk 3 with a disk size of 25 GB first and then Disk 4 with a disk size of 50 GB.

  4. Select Memory and set the value to 18 GB.
  5. Select CPU and set the Number of virtual sockets value to 4.
  6. Extend the size of Disk 1 to 50 GB.
    1. Select Disk 1.
    2. Change the size to 50 GB.
    3. Click OK.
  7. Click Add above the Resources table to add a virtual disk.
  8. Select Hard Disk for the Device Type.
  9. Click Next.
  10. Select Create a new virtual disk.
  11. Select Thin Provision.
  12. Click Next.
  13. Set disk size value to 50 GB.
  14. Select Store with the virtual machine.
  15. Click Next.
  16. Verify that the Independent option is deselected for Mode and SCSI (0:3) is selected for Virtual Device Mode.
  17. Click Next.

    If prompted to accept recommended settings, accept the recommended settings.
