[17005] Server unable to take control of SAN

PSAlert_17005_SP_ALERT_CANT_FENCE_Monitor (UnitMonitor)

Knowledge Base article:

Summary

Matrix Server is unable to exclude servers that have become unresponsive, or to verify the fencing of servers that were previously fenced and have not yet been rebooted. Possibly the fencing device is not responding to the fencing request or the Ethernet connection to the FibreChannel switch has failed. Also check for other networking or SAN hardware problems. The servers should be rebooted as soon as possible.

Alert Message

Server unable to take control of SAN

This {0} is unable to take control of SAN because the servers are unable to perform fencing operations, possibly due to a networking or fencing hardware failure or misconfiguration. As a result, some or all filesystem operations may be paused throughout the {1}. In addition, filesystem mounts and unmounts and disk imports and deports cannot be performed.
