To switch over the cluster application when the slice of the operating node is ACTIVE and the slice of the standby node is in any status except STOP (when the slice is detached) among the slices that configure the netmirror volume, check the status of the network that is used for the mirroring among servers.
If the cluster application is switched over when the slice of the standby node is detached as well as the network is disconnected, operation will stop. This is because on the new operating node, the slice on the disk of the own node is detached and cannot be used, and the disk on another node cannot be used due to the disconnected network. At the same time, offline processing of the cluster application may fail on the new operating node, and the node may panic.
