Thank you for your answer. So,I think if the network has problem, the NAS service is problem too. Administrator team have to manually take failover NAS service to other head. That's right or not. Pls help to suggest me. How can we protect this event.
If I compare with netapp product, it can failover to other controller. Our customer still expect that 7420 should be the same feature on Netapp product. When the Oracle will support this feature. Pls help me.
Thank you so much.
Administrator can manual switch service from one node to other.
Every node monitor that all services running normal and restart him when sevice died. It's not cluster features, it's features of single node.
NetApp can failover from one node to other, but it's not happen automaticaly when one node lost some network connections.
So it't look same as ZFS storage.
For resolve network problem you should configure link agregation or IPMP. It's protect from lost some network links without requirrements initiate cluster failover.
Happy New year, thank you for your suggestion.
Our customer known Cluster & IPMP feature on 7420c already. They still need the cluster failover , if the IPMP fail. So,I recommend them to have workflow script and monitor the IPMP with alert action. If the IPMP fail, the NAS controller'll reboot by workflow script.
Have you see the failover workflow script which use with the IPMP fail ?
