[13907] Failed to fence server

PSAlert_13907_SCL_ALERT_FENCEFAIL_NOTIME_Monitor (UnitMonitor)

Knowledge Base article:

Summary

Matrix Server cannot fence a server that is no longer communicating with the matrix. Either reboot the server or run the mx server markdown command to restore normal operations. Before using this command, be sure that the server is physically down. If the command is run on a server that is not down, filesystem corruption can occur. See "Server Cannot Be Fenced" in the Matrix Server Administration Guide for more information.

Failed to fence server

Reboot {0} ASAP. It is no longer in communication with the {1}, and may be dirty, but attempts to exclude it from the SAN were unsuccessful. Rebooting it will allow normal {2} operation to continue. Alternatively, if the server cannot be rebooted, but can be confirmed to have no access to the SAN, run "mx server markdown <server>" to restore normal {3} operation.
