Red Hat Enterprise Linux (RHEL); including

- Red Hat Enterprise Linux Server 5 (with the High Availability and Resilient Storage Add Ons)
- Red Hat Enterprise Linux Server 6 (with the High Availability and Resilient Storage Add Ons)
Red Hat High Availability Cluster with 2 or more nodes
- Most common with power-fencing agents, but can affect fabric fencing if kdump or Diskdump is configured to dump the vmcore to SAN-based storage.
Kdump (RHEL5/6) or Netdump/Diskdump (RHEL4) is configured on the cluster nodes.
