ECS 3.6.1 Administration Guide

Lock and unlock nodes using the ECS Portal

You can use the ECS Portal to lock and unlock remote SSH access to ECS nodes.

1. Log in as the emcsecurity user.
   For the initial login for this user, you are prompted to change the password and log back in.
2. In the ECS Portal, select Settings > Platform Locking.
   The Platform Locking page lists the nodes in the cluster and displays the lock status.

   The node states are:

   • Unlocked: Displays an open green lock icon and the Lock action button.
   • Locked: Displays a closed red lock icon and the Unlock action button.
   • Offline: Displays a circle-with-slash icon but no action button because the node is unreachable and the lock state cannot be determined.
3. Perform any of the following steps.
   1. Click Lock in the Actions column beside the node you want to lock.
      Any user who is remotely logged in by SSH or CLI has approximately five minutes to exit before their session is terminated. An impending shutdown message appears on the user's terminal screen.
   2. Click Unlock in the Actions column beside the node you want to unlock.
      The admin default node user can remotely log in to the node after a few minutes.
   3. Click Lock the VDC if you want to lock all unlocked, online nodes in the VDC.
      It does not set a state where a new or offline node is automatically locked once detected.
