PAR Technologies V5 manual Resolve nodes, Restart nodes

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 ofnodes 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. nodesIf 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.
