Node Hangs After Rebooting When Switchover is in Progress (4806621)

Problem Summary: If a device group switchover is in progress when a node joins the cluster, the joining node and the switchover operation may hang. Any attempts to access any device service will also hang. This is more likely to happen on a cluster with more than two nodes and if the file system mounted on the device is a VxFS file system.

Workaround: To avoid this situation, do not initiate device group switchovers while a node is joining the cluster. If this situation occurs, then all the cluster nodes must be rebooted to restore access to device groups.
