open-e failover for onapp cloud

[cloudtech]

Hello,

I have two SAN servers with volume replication with failover setup(active/passive). The failover status looks fine on both primary and secondary nodes. When I manually switch the primary node to suspend mode, the secondary node took the place, but all my onapp VMs are down. The volume replication is Consistent on both nodes before I initial the failover test. After I return the active server state to the primary server, the VMs are still down, I could not do any action like create, start, stop, restore backup, etc.

I am wondering how the onapp know the secondary SAN node. Do I need to manually change the storage configuration when the primary SAN node is down?

Anyone have experience with open-e failover for onapp cloud? Thank you.

Make sure the initiators are using the Virtual IP to make the iSCSI connections.
If there are any allow/deny rules or CHAP authentication being used, this needs to be the same on each node to allow proper connectivity.
This may help in the setup :

Thanks. I have Virtual IP on Client Storage Access network. Do you mean I need to use the Virtual IP on onapp cloud instead of the actual IP of the Storage Access network? I don't use CHAP authentication.

Yes, you need to use the virtualized IP that you et up when configuring the failover, for iSCSI traffic.
The nodes cant move the real NIC IP, we move the virtual IP to the active node.

Watch the video I provided, it will help make it clear.

I just watched the video and found out the answer. Thank you for your support.

If both SAN nodes are connecting to one switch, can open-e swap the Client storage Access link IP ?

Eg:

Primary node:
Client Storage Access: 192.168.2.220

Secondary node:
Client Storage Access: 192.168.2.221

When Primary node is down, the secondary node Client Storage Access IP changed to 192.168.2.220.
