  • Be sure the server has adequate resources (processor speed, hard drive space, and memory) for the software.
  • Be sure the server BIOS is current and the configuration is correct.
  • Be sure you have printed records of all troubleshooting information you have collected to this point.
  • Be sure you have two good backups before you start. Test the backups using a backup utility.
  • Check the operating system and application software resources to be sure you have the latest information.
  • If the last-known functioning configuration does not work, try to recover the system with operating system recovery software. For more information, see the operating system documentation.
If you recently upgraded the operating system or software and cannot resolve the issue, try restoring a previously saved version of the system. Before restoring the backup, make a backup of the current system. If restoring the previous system does not correct the issue, you can restore the current set to be sure you do not lose additional functionality.
For more information, see the documentation provided with the backup software.
Cause
  • The software might be incompatible with other software on the server.
  • Known issues might exist with the software.
  • The server configuration might have changed.
  • The server might be infected by a virus.
Action
  • Check the application log and operating system log for entries indicating why the software locked up.
  • Check for incompatibility with other software on the server.
  • Check the support website of the software vendor for known issues.
  • Review log files for changes made to the server that might have caused the issue.
  • Scan the server for viruses with an updated virus scan utility.
Symptom
  • The system locks up after settings were changed.
Cause
  • The new system settings are not supported.
Action
  • Check the system logs to determine what changes were made, and then change the settings back to the original configuration.
Please change the settings back to the original configuration. If more than one setting was changed, change the settings one at a time to isolate the cause of the issue.
Symptom
  • Errors occur after an application is installed on a server.
Action
  • Check the application log and operating system log for entries indicating why the software failed.
  • Check system settings to determine if they are the cause of the error. You might need to obtain the settings from the server setup utility and manually set the software switches. For more information, see the application documentation, the vendor website, or both.
  • Check for overwritten files. To determine which files are added by the application, see the application documentation.
  • Reinstall the application.
  • Be sure you have the most current drivers.
Network connection fails on remote communication by WebUI
Symptom
  • An error message describing the broken connection displays and the program exits.
Cause
  • Because network connectivity cannot be guaranteed, it is possible for the administrative client to become disconnected from the target server during the BIOS or BMC Firmware flash preparation. If any remote connectivity procedure fails during the BIOS or BMC Firmware flash online preparation, the flash does not occur for the target system.
Action
  1. Attempt to ascertain and correct the cause of connection failure.
  2. Restart the process.
Failure occurs during BIOS or BMC Firmware flash
Symptom
  • The server will not start.
Cause
  • The flash cannot be interrupted during BIOS or BMC Firmware flash, or the BIOS or BMC Firmware image is corrupted and the server does not start. The most likely reason for failure is a loss of power to the system during the flash process.
Action
  • Try the flash process again.
  • For BIOS flash process stop caused by power loss and cannot boot again, try BIOS recovery process.
  • Contact for repairing process if still not work.
Target system is not supported
Symptom
  • If the target system is not listed in the supported servers list, an error message appears and the program exits.
Cause
  • Only supported systems can be upgraded using the BMC WebUI.
Action
  • To determine if the server is supported, check BIOS or BMC Firmware release note and confirm the server model.
Symptom
  • The server does not boot.
Cause
  • The system BIOS or BMC Firmware flash process fails.
  • The system ROM is corrupt.
  • The server fails to boot after a BIOS or BMC Firmware update using update tool or BMC WebUI.
  • A logical drive is not configured on the RAID controller.
  • The controller boot order is not set properly.
  • RAID containing multiple logical drives might require the boot logical drive to be selected under Option ROM.
Action
  • For BIOS flash process fail cause server does not boot, try to use BMC WebUI to update BIOS again.
  • BIOS Recovery process.
  • For BMC Firmware process fail cause server doesn’t boot, contact for repairing process.
  • A logical drive is not configured on the RAID controller. Configure logical drive on RAID controller and set controller boot order properly.
  • Properly select boot logical drive under Option ROM when RAID containing multipul logical drives.
