If your UCP system uses a storage system, you must provision the UCP Advisor VM with a command device. It must be created in the meta_resource resource group.

Use the following procedure to provision a new command device to the UCP Advisor VM on the management node before you install UCP Advisor.
  1. Log on to vCenter Server Appliance.
  2. Right-click UCP Advisor VM, then select Edit Settings.
  3. In New device, click Select.
  4. Select RDM Disk, then click Add.

  5. Select the target LUN, then click OK.

  6. Click OK.
  7. Verify if the command device is eligible for provisioning. Enter:
    lsscsi -i

    Sample output:

    [ucpadmin@UCPAdvisorMasterHost105 ~]$ lsscsi -i
    [1:0:0:0]    disk    VMware   Virtual disk     2.0   /dev/sda   -
    [1:0:1:0]    disk    VMware   Virtual disk     2.0   /dev/sdb   -
    [1:0:2:0]    disk    HITACHI  OPEN-V-CM        5001  /dev/sdc   360060e80282742005080274200000049
    [1:0:3:0]    disk    HITACHI  OPEN-V-CM        A301  /dev/sdd   360060e8028273e005080273e0000000a

    The disk attribute property for the command device that you are trying to add must be set to OPEN-V-CM.

    If the disk attribute property for the command device that you are trying to add is set to OPEN-V, you cannot provision it. To reset the property:

    1. Remove the command device from the UCP Advisor VM and the ESXi host.
    2. Create a new command device on the storage device, and assign it to ESXi host.
    3. Add the command device as a RDM disk to the UCP Advisor VM.
    4. Verify the disk attribute property of the command device again.
