Error Code details
Severity: Error 
Component: Cluster Server 
%s:Monitor hung for disk group %s. Halting the system.

This message displays when:

  1. The monitor does not complete within the specified time (60 seconds) for a specified resource.
  2. Veritas Cluster Server (VCS) tries a number of times to monitor the resource, yet all the attempts time out. (The FaultOnMonitorTimeouts attribute determines the number of tries. The default is 4.)

After VCS logs  this message, it initiates a system halt using the poweroff -nf command.

Platform: Red Hat Enterprise Linux 4 (x86-32), Red Hat Enterprise Linux 4 (IA-64), Red Hat Enterprise Linux 4 (x86-64)
Release: 5.0MP3

You can change the frequency of the attempts by updating the FaultOnMonitorTimeouts value. Do the following:

  1. Make the VCS cluster writable. Enter:

    # haconf -makerw
  2. Change the FaultOnMonitorTimeouts value. Enter:

    # hatype -modify DiskGroup FaultOnMonitorTimeouts new_value

    For example, the following command sets the FaultOnMonitorTimeouts value to 7.

    # hatype -modify DiskGroup FaultOnMonitorTimeouts 7
  3. Return the VCS cluster to read-only mode. Enter:

    # haconf -dump -makero
