scstest
tests PM in a SCOUT environment.
scstest
checks if the PM hardware and software
configurations are set properly. In this sense, scstest
i
sthe same as the cstest
program. However, unlike the
cstest
program, scstest
invokes remote
processes via SCOUT environment. Thus, scstest
program
must be invoked with in a SCOUT environment.
Users must specify the network which is defined on the
scorehosts.db
file. As a result, users do not have to
specify configuration (and firmware) file(s), becuase they are
specified in the scorehosts.db
file.
On large clusters, having more than hundred hosts, users had better to
use scstest
rather than cstest
or
rcstest
. cstest
and
rcstest
invoke remote processes using the
rsh
Unix (linux) command. Due to the limitation of
rsh
scalability, cstest
or
rcstest
may fail to invoke remote processes.
