My question is regarding the a node path failure. But we have one linux server, where was installed Oracle database. For example, you can configure dm-multipath for SCSI mpath devices for SCSI LUNs and use NVMe multipath to configure NVMe-oF namespace devices on the host. Both of these methods allow a storage controller and a host to use aggregated bandwidth, and both can survive the failure of one of the paths from host to storage controller. however if I restart both VMs SQL01 and SQL02 the problem will disappeared from netapp Recovery Guru but after some times this problem will come again.
