• Query to check the vCenter Domain join status gives below output: 
  

  #/opt/likewise/bin/domainjoin-cli query

  Error: LW_ERROR_DOMAIN_IS_OFFLINE [code 0x00009cb9]

  The domain is offline
  
  

Cause

There are several causes for this issue, such as:

• The system is unable to establish contact with the original Active Directory domain or its Domain Controller.

• Connectivity to the source domain or its respective Domain Controller has been lost.

• The previous domain's infrastructure is no longer active, having been either decommissioned or entirely removed.

   

• The source Active Directory domain to which the system was joined has been retired or no longer exists.

• The original domain has been taken offline or permanently dissolved.

• Domain Controller IP changed, or source domain no longer exists.

Resolution

Note: Take Snapshot of the vCenter server (Offline Snapshot of all the vCenter servers if in linked mode).

1. Access VCSA via SSH:
   • Ensure SSH is enabled on the vCenter Server Appliance (VCSA).
   • Connect to the VCSA using an SSH client (e.g., PuTTY) and log in as root.
     
     
2. Disjoin from Active Directory:
   • Execute the following command to remove the VCSA from its current Active Directory domain:
# /opt/likewise/bin/domainjoin-cli leave
     
     
   • You will be prompted for the domain administrator's password to complete this action.
     
     
3. Reboot the VCSA:
   • After successfully disjoining from the domain, reboot the vCenter Server Appliance to apply the changes:
     # reboot
     
     
4. Attempt Hostname Modification:
   • Once the VCSA has fully restarted, access the VAMI (vCenter Server Appliance Management Interface) at https://<vCenter_IP_or_old_Hostname>:5480.
   • Navigate to the networking section and retry changing the vCenter hostname.
