Troubleshooting 79LED Behavior PatternsThe external SAS ports on the PERC 5/E Adapter have a port status LED per x4 SAS port. This bi-colorLED displays the status of any external SAS port. The LED indicates whether all links are functional oronly partial links are functional. Table 6-7 describes the patterns for the port status.Audible Alarm WarningsAn audible alarm is available on the PERC 5/E Adapter to alert you of key critical and warning eventsinvolving the virtual disk or physical disk problems. You can use the Basic Input/Output System (BIOS)Configuration Utility to enable, disable, or silence the on-board alarm tone.NOTE: Silencing the alarm stops only the current alarm, but future alarms will be sounded. To permanently disablethe alarm, select the disable alarm option.smartd[smartd[2338]Device: /dev/sda, BadIEC (SMART) modepage, err=-5, skipdevicesmartd[2338] Unableto register SCSIdevice /dev/sda atline 1 of file/etc/smartd.confThese error messages are caused by an unsupported command coming directlyfrom the user application. This is a known issue in which user applications try todirect Command Descriptor Blocks to RAID volumes. This error message has noeffect on the user and there is no loss of functionality due to this error.The Mode Sense/Select command is supported by firmware on the PERC 5.However, the Linux kernel daemon is issuing the command to the virtual diskinstead of to the driver IOCTL node. This action is not supported.Table 6-7.
