Table 3-1. Service procedure tools
Utility (see note) Runs on Description
fault_service_Worm_RTG All nodes Monitors the switch for faults. It restarts the switch if a
fault is detected.
fs_monitor All nodes Monitors the adapter for interrupts that have not been
serviced. This is required because of a hardware
oversight in MSMU, in which there is a window in time
that causes it to hold interrupts and then forget to
introduce them.
rc.switch All nodes Starts the daemons and IP configuration tools.
Estart Primary or
Control Node
Tunes the switch and puts it into run phase. Also, kicks
off the route table generator and distributes the routes to
the nodes, by placing them in the etc/SP directory on
the control node.
Estart_sw Primary or
Control Node
This is the primary-node command to start the RS/6000
SP High Performance Switch. Estart_sw is called by
Estart. It is useful to note that the time-out variable
(LIMIT) for the Estart process is located in this file. This
may have to adjusted for systems that take longer to
tune than in other systems.
Eprimary All nodes Sets a node as the primary node.
Eprotocol All nodes Stores switch protocol information in the System Data
Repository for a node or a series of nodes. Also
retrieves a topology files out of the SDR.
Eclock Primary or
Control Node

indicate if this is a primary or secondary node, the
associated switch chip information, and IP address
information.
rc.switch.log.previous All nodes A copy the previous run of rc.switch.
expected.top.no_comments All nodes Used by rc.switch to more easily parse out chip
connection information.
