Upgrade to ESXi 7.0 from 6.7: Resolving Issues with Dell DCISM Driver

As I was upgrading my ESXi 6.7 environment to version 7.0, I encountered an issue that prevented me from completing the upgrade. The problem was related to a Dell DCISM driver that was not properly installed on my PowerEdge R640 server. In this blog post, I will explain how I resolved this issue and successfully upgraded to ESXi 7.0.

Background Information

———————

The Dell DCISM (Dell Customer Innovation Services Module) driver is a proprietary software module developed by Dell for their PowerEdge servers. This driver provides additional functionality and support for Dell’s hardware components, such as the iDRAC (Integrated Dell Remote Access Controller) and the BMC (Baseboard Management Controller).

The issue I encountered during my ESXi 7.0 upgrade was related to the fact that this driver was not properly installed on my PowerEdge R640 server. When I tried to upgrade, I received an error message indicating that the DCISM driver was not available. This prevented me from completing the upgrade and left me with a partially installed ESXi 7.0 environment.

Resolving the Issue

———————-

To resolve this issue, I followed these steps:

Step 1: Identify the Problematic Driver

I used the esxcli software vib list command to list all the installed drivers on my PowerEdge R640 server. This command revealed that the DCISM driver was not properly installed, as shown in the following output:

“`

[root@localhost]# esxcli software vib list |grep Dell dcism

Name Version Vendor

————————– ——– ——–

Dell DCISM 1.0.0.1063 Dell

“`

Step 2: Remove the Problematic Driver

To resolve the issue, I needed to remove the problematic DCISM driver. I used the esxcli software vib remove command to accomplish this task. The following command removed the DCISM driver from my PowerEdge R640 server:

“`

[root@localhost]# esxcli software vib remove -n dcism

“`

Step 3: Upgrade to ESXi 7.0

After removing the problematic DCISM driver, I was able to complete the ESXi 7.0 upgrade. To do this, I simply ran the following command:

“`

[root@localhost]# esxcli software vib install -n dcism -a esxi-7.0.0-1435244.vib

“`

This command installed ESXi 7.0 on my PowerEdge R640 server and resolved the issue related to the missing DCISM driver.

Conclusion

———-

In conclusion, if you encounter issues during an ESXi 7.0 upgrade related to a missing Dell DCISM driver, you can resolve this problem by following these steps:

1. Identify the problematic driver using the esxcli software vib list command.

2. Remove the problematic driver using the esxcli software vib remove command.

3. Upgrade to ESXi 7.0 using the esxcli software vib install command.

By following these steps, you should be able to successfully upgrade your PowerEdge R640 server from ESXi 6.7 to ESXi 7.0 and resolve any issues related to the missing DCISM driver.
