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.
- Log on to vCenter Server Appliance.
- Right-click UCP Advisor VM, then select Edit Settings.
- In New device, click Select.
- Select RDM Disk, then click Add.
- Select the target LUN, then click OK.
- Click OK.
- 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:
- Remove the command device from the UCP Advisor VM and the ESXi host.
- Create a new command device on the storage device, and assign it to ESXi host.
- Add the command device as a RDM disk to the UCP Advisor VM.
- Verify the disk attribute property of the command device again.
