You can use the ECS Portal to lock and unlock remote SSH access to ECS nodes.
Prerequisites
This operation requires the Security Administrator role assigned to the
emcsecurity user in ECS.
About this task
Locking affects only the ability to remotely access (SSH to) the locked nodes. Locking does not change the way the ECS Portal and the ECS Management REST APIs access nodes, and it does not affect the ability to directly connect to a node through the management switch.
Steps
Log in as the
emcsecurity user.
For the initial login for this user, you are prompted to change the password and log back in.
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.
Perform any of the following steps.
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.
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.
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.
