Maintenance Mode Overview
In Junos Space, maintenance mode is a special mode that an administrator can use to perform database restore or debugging tasks while all nodes in the fabric are shutdown and the Junos Space web proxy is running.
The Junos Space system goes into maintenance mode in the following cases:
- Junos Space goes down.
The system will go into maintenance mode when Junos Space is down on all nodes in the fabric. Users attempting to log in when the system is in maintenance mode are redirected to the maintenance mode log in screen. Users who logged in to Junos Space before the shutdown and attempt to perform an action in the user interface are also redirected to the maintenance mode log in screen.
- An authorized Junos Space administrator initiates a Restore database action.
When a user initiates a Restore database action, Junos Space prompts the user for user name and password to enter maintenance mode, as shown in Authentication Required window. After the user is authenticated, Junos Space initiates the restore database operation and the system remains in maintenance mode until the database is restored and the user exits maintenance mode.
- A Junos Space administrator connects to an appliance
in maintenance mode using the URL
https://ip-address/maintenance, where ip-address is the Web access IP address for the appliance.
When a user is authenticated to access Junos Space in maintenance mode, the Maintenance Mode Actions menu displays the tasks a user can perform in Maintenance Mode.
When a user exits maintenance mode, Junos Space is restarted. After several minutes, the system returns to normal operational mode, and Junos Space users can log in to the user interface.
Maintenance Mode Access and System Locking
Only one maintenance mode administrator can access the maintenance mode landing page at a time. When an administrator logs in to maintenance mode, Junos Space locks the landing page. When a second administrator attempts to log in to maintenance mode while the first administrator is logged in, Junos Space displays a message indicating that another administrator is currently logged in to the system and the Maintenance Mode landing page is locked. The maintenance mode lock is released when the first administrator logs out or the lock times out. If the logged-in administrator is inactive for a period of time, the maintenance mode lock is released after 5 minutes, and another administrator can log in.
Maintenance Mode User Administration
The user name for the maintenance mode administrator is “maintenance”.
The password for the maintenance mode administrator is set from the Junos Space system console during the initial installation/configuration of a Junos Space appliance or virtual appliance.
