You can report failure information (SIM) about storage systems through Syslog, SNMP trap, and email. Failure information reported through email is the same as SIM displayed on the Alert window or reported through SNMP trap. For SNMP trap, the user needs to access the SNMP Manager to check for failure. However, for report through Syslog or email, the user has only to check Syslog or email to know about the occurrence of failure. For methods of notification with SNMP traps, see the SNMP Agent User Guide.
Note: If an inactive GUM is detected during GUM status monitoring, the GUM might be rebooted. When that occurs, LAN communications become temporarily disabled, pinging devices becomes temporarily disabled, and the connected LAN port links go down and up. If monitoring is performed using SNMP, a ColdStart trap is issued.
After the GUM reboot is completed, the GUM is automatically restored to the normal status. As long as the LAN port link is up, and the network communication failure or the ping failure is corrected, you do not need to take any action.
