1. Disk Space Issues:
-SSH into SDDC Manager, login as vcf, login to root with the command su root.
-Check the disk space with the following command:
df -h
-Check if any of the partitions on SDDC Manager are over 80%
-cd into any full directories and clear out files as needed to clean up space

2. SSO password changed/does not match:
-Run the command: lookup_passwords and grab the password for resource PSC
This will grab the password for the [email protected] account. To test if this password was changed/does not match, login to the vCenter UI with the [email protected] account and password from SDDC Manager. If it fails to login, the password was changed.
To resolve:
-Reset the password to a temporary password with KB: Reset SSO Password . Then login to the vCenter with the [email protected] account and temporary password. In the right-hand side of the UI where the account shows, click on the account > Change password. Put in the temp password for the current password and the new password should be the one pulled from SDDC Manager.
3. Root vCenter password changed/does not match
-Run the command: lookup_passwords and grab the password for resource VCENTER
This will grab the password for the root account on the vCenter. To test if this password was changed/does not match, SSH into vCenter directly with the password from SDDC Manager. If it fails to login the password is either locked out or does not match.
Follow KB: Reset Passwords to unlock and reset
4. SDDC Manager Certificate is expired
-If the SDDC Manager Certificate is expired we will not be able to access the SDDC Manager UI. To check if that certificate is expired, run VDT on SDDC Manager
-If it is expired, run KB: Reset SDDC Manager Certificate to replace the certificate
5. SDDC Manager does not trust the MGMT vCenter Root Certificate
-To rule this out run KB: Import vCenter Root Cert into SDDC Manager Truststore and run the root sync script to check if the MGMT vCenter Root Certificate is in the SDDC Manager truststores.
If it is not, follow the script to add to the trust stores.
6. NTP
-This can cause slowness within the UI and potentially have the UI not load
-Run these commands to check NTP and reset:
ntpq -p
systemctl stop ntpd.service
ntpdate ntp_server_ip
systemctl start ntpd.service
systemctl restart ntpd.service
ntpq -p
