ISS Technology Update Volume 7, Number 1 Scenario Behavior* which time the system will lose power. Single/Multiple fan(s) fail; OS without health driver The error is logged in the IML. iLO will attempt to perform a graceful shutdown by simulating an ACPI power button press; however, this will have no effect in Windows if the console is locked. The system continues to run until thermal sensors reach the hardware protection limit, at which time the system powers down immediately. *Depending upon the setting for the Insight Agents and the monitoring of SNMP traps, the system administrator may be notified in the event of a fan failure. Models without redundant fans ProLiant DL and ML servers without redundant fans are shown in Table 5-3: Table 5-3. ProLiant ML and DL servers without redundant fans ProLiant DL servers ProLiant ML servers DL110 ML110 DL140 ML115 DL145 ML150 DL160 ML310 DL320 NOTE: Redundant fans are planned for DL160, DL165, DL180, and DL185 for implementation before the end of the first quarter 2008. Failure behavior of models without redundant fans ProLiant DL and ML servers without redundant fans respond differently to a fan failure based upon the state of the server when the failure occurs, the presence of the health driver, and the system's thermal shutdown configuration. Table 5-4 identifies various fan failure scenarios and the resulting behavior. Table 5-4. Failure behavior of ProLiant DL and ML servers without redundant fans Scenario Behavior* Single/multiple fan(s) fail during POST The error is logged in the IML. The system boots to the point that the ROM checks the fan configuration. ROM will terminate POST and restart the server. Single fan fails in OS with health driver (thermal shutdown enabled) The error is logged in the IML by the iLO management processor. The error is logged to an OS log if the health driver is operational. The health driver initiates a graceful shutdown. Single/Multiple fan(s) fail in OS with health driver (thermal shutdown disabled) The error is logged in the IML by the iLO management processor. The error is logged to the OS logs by the health driver. Health driver is not currently supported in the 100-series systems, but it will be supported in next-generation 100series systems. The 100-series servers do not have an IML; instead, they have a IPMI log called the System Event Log (SEL). iLO2 supports the SEL log and logs only critical errors to it. The system continues to run until thermal sensors reach the hardware protection 12
