HP Medical Archive
Server Manager Operation
Starting Services
This button is used to start services that have been stopped for
upgrade or other configuration changes.
Upon server startup, or when commanded via the Start All button, the
Server Manager executes a series of scripts to initiate dependent appli-
cations in a sequence that ensures prerequisite services are running
before starting the grid services themselves.
The operating system kernel, environment, and hardware services for
storage and networking are verified first. Following the operating
system services, time synchronization is verified. This process can take
several minutes while the system characterizes and builds trust in the
time signal source.
Any third-party applications required to support the grid service
software on the server are started, if not already running.
Finally the HP Medical Archive services are started and the server
joins the grid. Any services already running are not disrupted.
Stopping Services
The command button to Stop All can be used to gracefully stop
services hosted on this server, effectively disconnecting it from the
grid. The operating system and Server Manager continue to run on the
server, allowing you to perform tasks such as configuration changes,
software updates, and similar maintenance that requires the operating
system. Grid services and third-party applications are stopped.
When maintenance tasks are finished, you can either:
Start All services to gracefully start the grid services and rejoin the
grid (page 200).
— or —
Restart the server; bootstrapping the operating system and then
starting grid services (below).
Restarting the Server
This command gracefully stops the grid services, and also brings
down the operating system to perform an automatic reboot. This is
useful for resetting a server that has failed, or starting a new
configuration.
