Cause

By default, VPXA uses "Resources"(ha-root-pool) as the root resource pool and it is suggested not to assign the same name to user resource pools.

Resolution

To resolve this issue:

1. Disconnect the host and remove from vCenter inventory.
2. Stop vpxa.
3. Rename the user created 'Resources' resource pool via vCenter as some different name.
4. SSH to ESXi host and take backup of pools.xml in /tmp location.
5. Remove the pools.xml file. (rm -f /etc/vmware/hostd/pools.xml)
6. Restart vpxa.
7. Add the host back to vCenter.
