Environment

VMware Cloud Foundation 2.2.x

Cause

When a custom L3 uplink configuration is used, the sos utility is unable to accurately report on the health of the uplink configuration.

Resolution

To resolve this issue, use the following steps to update the sos utility.

1. Download the attached 55666_sos-2.2.1-8598083.noarch.zip file.
2. Use a file transfer utility to copy the 55666_sos-2.2.1-8598083.noarch.zip to the /tmp folder on the SDDC Manager Controller virtual machine.
3. Log in to the SDDC Manager controller virtual machine as the root user.
4. Issue the following command to extract the contents of the /tmp/55666_sos-2.2.1-8598083.noarch.zip file:

unzip -d /tmp/ /tmp/55666_sos-2.2.1-8598083.noarch.zip

5. Issue the following command to install the updated sos utility:

rpm -Uhv /tmp/sddc-support-2.2.1-8598083.noarch.rpm

Note: You will see output similar to the following:
