The clusterForceRemoveServer Web API Method

Remove a server from the cluster. The removal process may be asynchronous if Session Clustering is used – if this is the case, the initial operation will return an HTTP 202 response. As long as the server is not fully removed, further calls to remove the same server should be idempotent. On a Zend Server with no valid license, this operation will fail.

Version: 1.3

Required Permissions: full

HTTP method: POST

Supported by Editions: Zend Server

Request Parameters:

Parameter	Type	Required	Description
serverId	String	Yes	The server ID

Expected Response Code:

200 OK - The server removal process was completed successfully. This status is expected if there is no need to perform a graceful shutdown process, or if the Force option was set to "TRUE".
202 Accepted - The removal process has started but not completed yet. The user may want to check the server status within a few seconds using the clusterGetServerStatus method to verify that the operation was completed.

Response Type: serverInfo with the status of the server being removed. The status is expected to be either shuttingDown or removed.

Possible Action Specific Error Codes:

HTTP Code	Error Code	Description
404	noSuchServer	There is no server with the provided server ID.
500	cantConnectToServer	Zend Server is unable to connect to the specified server.
500	invalidServerResponse	An invalid or unexpected response from the server.
503	temporarilyLocked	The server cannot be removed because another server in the cluster is performing a graceful startup/shutdown.
405	notImplementedByEdition	The method is not implemented by this edition of Zend Server.
