Remotecopy Hyper-V Failovercluster with HP3PAR 7200 storage

We have several Microsoft Cluster (2012,2016 and 2019) on two datacenter which were configured with  

Remotecopy (Synchronous mode) . Original volume and Remotecopy volume were exported to the hosts. all Luns were visible. But when I move VMs to a host to reboot the empty host I lost ClustershareVolumes and all VMs are unacessible.  Pathmanagement and Autofailover was enbaled in Remote

Copy Groups. I have this behavior with all operating systems. I have tested it on IBM Bladecenter and HP .

Even moving the cluster volumes does not work.

Gen9 machines. Now I have unexported Remotecopy volumes , but therefore I have no transparent failover.

 

Thank you for your help !

Hi Günter Niersbach

Thank you for coming on HPE community forums.

I would like to know
1. Does every host lose all volumes when on host is rebooted? Or is it only within one cluster?
2. How is your zoning? (Assuming FC SAN)
3. What's your 3PAR OS version? (with patches?)
4. As you're saying VMs, I'm assuming Hyper-V?
5. Was "Path verify" or similar activated in MPIO configuration? (Not Sure this is relevant)

Hi  Mahesh202 

1. only the CSV Volumes which was activ on the rebooted Host was lost.

2. Zoning is so that the hosts have  4 paths to the first 3PAR and 4 paths to the second  3PAR

3.  3.2.2.709 (MU6)+P99,P107,P119,P131,P135,P138,P139,P146,P149

Hi Günter Niersbach

Thank you for responding to the questions asked.

I request you to please verify :

• The Subnet used by Failover Cluster LAN/Public network on all nodes is defined in Active Directory Sites. and Services
• Whether if it is pointing to the correct AD Site.
