Customers: if you are notified of this alert message, check to see that a call home alert was sent to Dell through the Support site. This error does generate a call home, and if a case has already been created, the Dell Support staff follows up on the alert. It usually takes less than an hour to receive a call home alert of this nature.
If you have lost access to the unit, or the DLm is not mounting tapes, contact DLm Support immediately.

Support staff: Troubleshoot the alert using the information obtained from the System event log. If you are unable to connect to the command line, attempt to connect to the iDRAC interface to see if the unit can be power cycled. If the unit does not respond to iDRAC commands, send a field resource on site to replace the VTE, if needed.

If the unit is accessible, gather the necessary information to troubleshoot the alert.
