Steps to Reproduce:
1. Create DC with 3 hosts connected to one SD, and in beginning they in following state
Host-A – Maintenance 
Host-B – Maintenance 
Host-C – Active (SPM)
2. Second step
Host-A – Maintenance 
Host-B – Active (HSM) 
Host-C – Active (SPM)
3. Step 3
Host-A – Maintenance 
Host-B – Active (SPM) 
Host-C – Maintenance
4. Step 4
Host-A – Active (HSM) 
Host-B – Active (SPM) 
Host-C – Maintenance
5. Step 5
Host-A – Active (SPM) 
Host-B – Maintenance
Host-C – Maintenance
6. Step 6, activate Host-B & Host-C
Host-A – Active (SPM) 
Host-B – Active (HSM) 
Host-C – Unassigned - Failed activate
