hwstart [hw { hw | all } ] [nodes]
Start the declared hardware on the selected nodes.
Starting a specific hardware will be tried on the selected nodes regardless, if this hardware is specified
for this nodes within the parastation.conf configuration file or not. On the other hand, if hw all
is specified or the hw option is missing at all, only the hardware types specified within the configuration
file are started.
Starting or stopping a specific communication hardware only concerns the ParaStation part of hardware
handling. I.e. stopping ethernet hardware should not touch the normal IP traffic running over this
specific device.
hwstop [hw { hw | all } ] [nodes]
Stop the declared hardware on the selected nodes.
If hw all is specified or the hw option is missing at all, all running hardware for this node is stopped.
Starting or stopping a specific communication hardware only concerns the ParaStation part of hardware
handling. I.e. stopping ethernet hardware should not touch the normal IP traffic running over this
specific device.
resolve [nodes]
Resolves a list of IDs to node names. Nodes selects one or more ranges of nodes. Nodes is either
of the form s1[-e1]{,si[-ei]}*, where the s and e are positiv numbers representing ParaStation IDs, or
'all'. Each comma-separated part of nodes denotes a range of nodes. If a range's '-e' part is missing,
it represents a single node. In principle nodes might contain an unlimited number of ranges. If nodes
value is 'all', all nodes of the ParaStation cluster are selected. If nodes is empty, the node range
preselected via the 'range' command is used. The default preselected node range contains all nodes
of the ParaStation cluster.
As an extension nodes might also be a hostname that can be resolved into a valid ParaStation ID.
reset [hw] [nodes]
Reset the ParaStation daemon on all selected node(s). As a consequence all processes using the
selected node(s) are killed!
If the option hw is given, additionally the communication hardware is brought into a known state.
Executing reset hw is the same as using restart.
restart [nodes]
Restart the ParaStation system on all selected node(s). This includes re-initialization of the
communication hardware. On the selected node(s) the ParaStation daemon processes are forced to
reinitialize the ParaStation cluster. As a consequence all processes using the selected node(s)s are
killed!
This is the same as using reset hw.
