Troubleshooting Guide

This page contains common troubleshooting issues and solutions for Mantle deployments.

General Troubleshooting

Mantle Lockout After Three Wrong Passwords

Description:
Entering an incorrect password three times can lock Mantle for 15 minutes.

Solution:

  • Wait 15 minutes before retrying.
  • Ensure you enter the correct credentials.
  • If access is required immediately, contact an administrator.

DHCP Lease Assigned Before BIOS Process Completes

Description:
If an IP is leased before the BIOS process is completed, it means another device (e.g., a laptop) is pulling the IP.

Solution:

  • Set a static IP on all build network devices to prevent them from obtaining a DHCP lease from the container.

Interrupted HPE EL8000 Datacenter Build

Description:

  • If the build is interrupted after leasing all IPs, servers will continue to look for API calls.
  • Restarting the build immediately will cause API calls to all blades at the start, leading to a failure.

Solution:

  • Best practice: Power cycle the devices before starting another build to reset the state.

USB Issues

No USB1 Cable Connected on EL8000

  • Cause: Missing USB1 cable prevents the BIOS process.
  • Solution: Verify and properly connect the USB1 cable.

No USB Cables Connected at All

  • Cause: Lack of required USB cables will cause build failures.
  • Solution: Ensure all required USB cables are connected before starting a build.

Incorrect Password for HPE EL8000

  • Cause: Entering the wrong password can cause authentication failures.
  • Solution: Verify and enter the correct password.

Incorrect Write/Erase USB

  • Cause: Using the server USB instead of the correct USB for Write/Erase.
  • Solution: Ensure you use the correct USB when performing Write/Erase operations.

Incorrect USB for Network Build

  • Cause: Using the server USB instead of the correct USB for network build.
  • Solution: Use the correct USB for network build operations.

Adding Hosts to DSwitch Error

Description

  • This issue occurs in some HPE EL8000 datacenter builds.
  • Initially thought to be caused by switch modules not communicating with blades.
  • The issue can also be caused by a blade not being seated correctly in the chassis backplane.

Solution Steps

In some specific HPE EL8000 datacenter builds, the user may come across this error below

Step 1: Log in to the Chassis Manager and Each ILO

  1. Access the Chassis Manager.
  2. Log in to each ILO.
  3. Refer to the image below:

Step 2: Check Network Adapters in ILO

  1. Navigate to System Information > Network.
  2. You should see two physical adapters:
  3. One to the backplane.
  4. One to the network controller.
  5. If only one adapter is visible:
  6. The blade is not communicating with the switch modules.
  7. Turn off the blade before reseating or replacing it.

Refer to the image below:

Step 3: Check Switch Modules

  1. If all blades show both adapters, the issue may be with the switch modules.
  2. Pull out the switch modules and reseat them.

Refer to the image below:

Step 4: Check for Hardware Failures

  1. If the issue persists after reseating blades and switch modules:
  2. There may be a hardware failure in the EL8000.
  3. Contact HPE support.

Conclusion

By following these troubleshooting steps, most EL8000 DSwitch errors can be resolved. If the problem persists, escalate to hardware support.
