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.
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 ?
