Perform a Power On Self Test (POST)

Applies to CA6000 and CA6300 appliances

Perform a Power On Self Test (POST) to assess the hardware status. Use the diagnostic information on the terminal display to help identify hardware issues. Note that the system log, located in /var/log/messages, also logs diagnostic information, however, the terminal display is the most complete source of diagnostic information.

Be sure to resolve any hardware issues before you upgrade CA Multi-Port Monitor.

The example below shows the CA6300. The CA6000 will report similar results for each of the two RAID controllers. In this example the status of the single CA6300 RAID controller is optimal, so no further action is required unless failed stripes are present:

On a restart of the appliance:

• The BIOS scan for every RAID array controller reports its current condition on the terminal display.
• If file system or physical disk corruption has occurred on the System or Data array that has not been detected by the RAID controller(s), it is possible that SCSI “sense” or “hang” errors will be displayed on the terminal.
• If XFS file system corruption has occurred, a kernel panic preceded by an XFS code call stack is displayed on the terminal.

To restart the CA6000 or CA6300 appliance, follow these steps:

1. Always stop the Vertica metrics database before restarting the appliance.
   1. Stop the Vertica metrics database.

      sudo /opt/NetQoS/scripts/doVerticaCmd.sh --shutdown 
      

2. Restart the appliance.

   sudo /sbin/shutdown -r now
   

   For the CA6000, the terminal displays the status of the BIOS scans on the System and Data RAID controllers.

   For the CA6300, the terminal displays the status of the BIOS scans on the single RAID controller.

3. Use the information on the terminal display to identify any issues. See the following sections for more information.
