Environment

VMware NSX-T

Cause

This issue occurs when host preparation fails to clean old VIBs.

Resolution

This issue is resolved in NSX-T 2.1.0, available at VMware Downloads.

To work around this issue if you do not want to upgrade, you need to manually clean all the VIBs by running the force remove option and then perform resolve on the install failure.

These are the commands to remove VIBs from various hypervisors:

• ESXi - esxcli software vib remove --vibname=<vib-name> --force --no-live-install
• Ubuntu KVM - dpkg --purge --force-all <vib-name>
• RHEL KVM - rpm -ev --nodeps <vib-name>
