Server Maintenance
Step 1 Choose Maintain > Servers > Server Shutdown. The Server Shutdown page is displayed.
Step 2 From the Server IP/Name drop-down list, choose the IP address or nickname of the server and click
Display. The server type and ID, as well as the array ID, are displayed.
Step 3 From the Shutdown drop-down list, choose Yes and click Submit.
Offloading a Server
The Server Offload page lets you set a server to Online or Offline. When a server is offline, the server
is configured to reject new provisioning; that is, new ingests are not allowed on a Vault and new streams
are not allowed on a Streamer and existing streams are moved to another Streamer gracefully.
Caching Nodes and Streamers
If HTTP is used as the cache-fill protocol between Caching Nodes and Streamers and the Caching Node
hosting the locate port is set to Offline, then a backup or available Caching Node in the same Cache
Group becomes the primary host of the locate port. If a backup or available Caching Node is set to
Offline, the state is changed from backup or available to not usable. This failover scenario is similar to
the Setup and Control server failover scenario for Streamers, in that all servers in the same group
advertise their availability to act as the primary with a backup taking over as primary if the primary
becomes unavailable because of offline status, losing connectivity, or failure.
Vaults
The Vault or ISV has two options for setting a server to offline:
• Offline (No Ingest)
• Offline (No Ingest & Fill)
The Offline (No Ingest) option enables the Vault or ISV to continue handling cache-fill requests and
mirroring activities, but the server does not participate in any new content ingests. The Offline (No
Ingest & Fill) option stops all cache-fill requests and any new content ingests, but the server still
participates in mirroring activities.
Note The protocoltiming log file only displays the "WARNING: Server is going OFFLINE" message when
the Offline (No Ingest & Fill) option is selected for Vaults.
The Offline (No Ingest) option for Vaults does not take the Vault completely offline, the Vault still
participates in mirroring and cache-fill traffic; therefore, the server going offline message is not
displayed in the protocoltiming log. The TRICKLE_DOWN file is used to determine the state of the
Vau l t f o r th e Offline (No Ingest) option.
To set a server to offline, do the following:
Step 1 Choose Maintain > Servers > Server Offload. The Server Offload page is displayed.
Step 2 From the Server IP/Name drop-down list, choose the IP address or nickname of the server and click
Display. The server type, server ID, array ID, and current status of the server are displayed.
