4.0.0 HP Polyserve Matrix Server Administration Guide (T5392-96052, March 2010)

Server: Enter the name or IP address of the server.
Server Severity: When a server fails completely because of a power failure or other
serious event, Matrix Server attempts to move any virtual hosts from the network
interfaces on the failed server to backup network interfaces on healthy servers in the
cluster.
When the original server is restored to normal operation (for example, the power is
restored and the server is rebooted), ClusterPulse uses the Server Severity to determine
whether it is possible to fail back virtual hosts to that server automatically. ClusterPulse
also considers each virtual host’s failback policy, which specifies whether it should
fail back or remain on the backup server. (See “Virtual hosts and failover” on page
196 for more information.)
The Server Severity can be configured on each server. The settings are:
AUTORECOVER. This is the default value for Server Severity. When the original server
is restored, Matrix Server can automatically fail back virtual hosts to that server,
depending on the virtual host’s failback policy.
NOAUTORECOVER. After the server recovers, it is not made available to host virtual
hosts. Instead, Matrix Server disables the server. (You will need to re-enable the
server with the PolyServe Management Console or mx utility). The NOAUTORECOVER
setting can be useful when integrating Matrix Server with custom applications, where
additional actions may be necessary after server recovery and before the server is
made available to host services provided by virtual hosts.
To update a server from the command line, use this command:
mx server update [--serverSeverity=autorecover|noautorecover] <server> ...
