Overview

You are seeing a management console error message: "Host cannot be put into maintenance mode to complete VIB installation. Cause: XXX uninitialized." The I/O Filter is running properly.

Solution

Accelerator management UI configuration screen reports this error when some of the VAIO configuration information in the vCenter database has become incorrect. Follow the steps below:

1. Navigate to the Accelerator Management UI.
2. Press the “Resolve Issues” button at the bottom of the screen.

The sfcbd-watchdog service (aka CIM service) on the ESXi host is either not running or has stopped working. Follow the steps below to fix the issue:

1. Start the SSH service on ESXi.
2. Open an SSH session to the ESXi host, and log in with the root credentials.
3. Run the following command to restart the sfcbd-watchdog service:
   

   /etc/init.d/sfcbd-watchdog restart

4. If sfcbd-watchdog restart command fails, reboot the ESXi host.
5. If restarting the sfcbd-watchdog service does not resolve the issue within two minutes, try restarting all management services on the host with the following command:
   

   services.sh restart

   
   It takes around four minutes for the services to restart. After the restart, the 'I/O filter' status should return to normal.
6. If the error message still persists, it may be due to vCenter inconsistency. Accelerator automatically synchronizes itself with any vCenter changes, but you can scan the vCenter manually by following the steps mentioned in the article Scanning the vCenter Manually.
