Hi,

for the Control Station you can use the Linux ps command.

For the data mover there isnt one - simply because it doesnt start processes on demand.
Its a microkernel that has a fixed set of "worker processes"

The specific services there have their own command to start/stop them like
server_iscsi ALL - service -status
but thats rarely needed - when the Celerra is booting it starts all the services that it has configurations for.

What exactly do you want to check for ?

regards
Rainer
