Study Notes

VCF Troubleshooting

SOS Tool (Supportability and Serviceability Tool) is a command-line Python tool.
SOS Tool can be invoked via API.
SOS performs checks and creates log bundles for VCF components.
Health checks are run.
Logs for VCF components are collected.
SOS commands cannot run if workflows are active in SDDC Manager.
SSH to SDDC Manager is required.
Use a VCF user account or access root with sudo privileges.
Enter the password when prompted.

Health Check Examples

--connectivity-health
--services-health
--ntp-health
--dns-health
--certificate-health
--password-health
--get-inventory-info
--health-check

Password Validity Example

/opt/vmware/sddc-support/sos -password-health -skip-known-host-check within the /home/vcf directory.
Checks component services user, changed date, expiry date, expiry in days, etc.

Collecting Log Files

Logs can be collected for all components within a specific domain without options.
sudo /opt/vmware/sddc-support/sos -domain-name MGMT for collecting logs in management domain.
Use --api-logs for specific API components.

Troubleshooting Recommended Steps

Expand workflow tasks in SDDC Manager to identify failed subtasks.
Note any errors displayed in the SDDC Manager UI.
Record the reference token ID in the relevant log.
