Troubleshooting PSOD Issues with QLogic Network Cards in ESXi Hosts
As a VMware administrator, you may have encountered the infamous Purple Screen of Death (PSOD) while working with ESXi hosts and QLogic network cards. In this blog post, we’ll explore the possible reasons for PSOD issues with QLogic network cards and provide steps to troubleshoot and resolve them.
Background
———-
QLogic network cards are widely used in ESXi hosts to provide Fibre Channel over Ethernet (FCoE) and iSCSI connectivity. The qfle3 driver and the qfle3f driver are used for FCoE and iSCSI communication, respectively. In some cases, the installation of these drivers can lead to PSOD issues in ESXi hosts.
Causes of PSOD Issues with QLogic Network Cards
———————————————-
There are several reasons why PSOD issues may occur with QLogic network cards in ESXi hosts:
### Outdated Driver Versions
If you have outdated driver versions installed on your ESXi hosts, it may cause PSOD issues. Ensure that you are using the latest version of the qfle3 and qfle3f drivers.
### Unused Protocols/Modules
If you don’t use iSCSI or FCoE protocols on your ESXi hosts, it’s recommended to remove them to avoid PSOD issues. However, if you do use these protocols, make sure to keep the drivers installed.
### Incorrect Driver Installation
In some cases, incorrect driver installation can lead to PSOD issues with QLogic network cards. Ensure that you install the correct drivers for your ESXi hosts.
### Network Adapter Issues
Network adapter issues can also cause PSOD problems with QLogic network cards in ESXi hosts. Check your network adapters and drivers to ensure they are properly configured and functioning correctly.
Troubleshooting and Resolving PSOD Issues with QLogic Network Cards
——————————————————————
To troubleshoot and resolve PSOD issues with QLogic network cards in ESXi hosts, follow these steps:
### Step 1: Check for Outdated Driver Versions
Use the esxcli software vib command to check for outdated driver versions. If you find any, update them to the latest version.
### Step 2: Remove Unused Protocols/Modules
Use the esxcli software vib remove command to remove unused protocols and modules from your ESXi hosts. Make sure to reboot your hosts after removing the drivers.
### Step 3: Check Network Adapters and Drivers
Check your network adapters and drivers using the esxcli network nic list and esxcli software vib remove commands. Ensure that you are using the correct drivers for your ESXi hosts.
### Step 4: Reboot Your Hosts
After removing unused protocols and modules, reboot your ESXi hosts to ensure that the changes take effect.
Conclusion
———-
In conclusion, PSOD issues with QLogic network cards in ESXi hosts can be caused by outdated driver versions, unused protocols/modules, incorrect driver installation, and network adapter issues. By following the troubleshooting steps outlined in this blog post, you can resolve PSOD issues and ensure that your ESXi hosts are running smoothly and efficiently.
Remember to always put your hosts into maintenance mode before making any changes to avoid disrupting your virtual infrastructure.
