Appendix B. SP daemons

The following daemons are specific to the SP servers and processor nodes:

|css.summlog

|(SRC subsystem name swtlog) This optional daemon collects |switch-related error log entries from all the nodes and stores them in a |single file on the control workstation. It runs on the control |workstation. |

|cssadm

|(SRC subsystem name swtadmd) This optional daemon runs on SP |Switch systems and responds to node switch events to perform Estarts if |necessary. It also performs switch clock recovery if switch or frame |power events occur. It runs on the control workstation. |

|cssadm2

|(SRC subsystem name swtadmd2) This optional daemon runs on SP |Switch2 systems and responds to node switch events to perform Estarts if |necessary. It runs on the control workstation. |

|emasterd

|(SRC subsystem name emaster) This daemon is required on SP |Switch2 systems if applications are using the Switch Clock API. It |establishes the Master Switch Sequencing (MSS) node, which provides switch |clock TOD synchronization. It responds to node switch events to perform |recovery actions for the MSS node. It runs on the control |workstation.

fault_service_Worm_RTG_SP

Fault-handling daemon for the SP Switch

haemd

Event Manager daemon: It matches information about the state of system resources with information about resource conditions that are of interest to client programs to create events; runs on all nodes of a system partition; one instance per system partition runs on the control workstation.

hagsglsmd

Group Services subsystem daemon: It provides global synchronization services, runs on all nodes of a system partition, and one instance per system partition runs on the control workstation.

hardmon

Hardware monitoring daemon that Interfaces to the serial port on each SP frame. It does tasks such as polling hardware for changes in hardware status, sending state changes to interested parties, sending commands to change power state and key lock position, and providing an interface to the S1 serial port of each processing node.

hatsd

Topology Services daemon: It provides information to other PSSP subsystems about the state of the nodes and adapters on the SP system. It runs on all nodes of a system partition. One instance per system partition runs on the control workstation.

hrd

Host responds daemon: It runs on the control workstation. See Appendix E, The System Data Repository for details. |

|hmcd

|Hardware monitoring daemon that is used by Hardmon to interface with the |HMC for hardware control and monitoring of IBM pSeries 690 |servers. It emulates an SP frame and node supervisor. The daemon |performs such tasks as polling the HMC for changes in server or LPAR status, |sending state changes back to Hardmon for dispersal to interested parties, |accepting commands from Hardmon to change the power state and sending |corresponding commands to the HMC to perform the action, and providing an |interface to the server and LPAR serial port consoles. One |hmcd daemon runs for every HMC defined for p690 logical |frames. If one HMC controls more than one p690 server, only one |hmcd daemon will be started by Hardmon to communicate to that |HMC. It has no command line interface.

kadmind

Kerberos V4 database administration server.

kerberos

Kerberos authentication server (does not run on nodes).

kpropd

Kerberos backup communication daemon (doesn't run on nodes).

pmand

The Event Management client daemon that dispatches actions based on subscribed-to events.

pmanrmd

Provides resource variables for problem management.

s70d

The hardware monitoring daemon used by Hardmon to interface with the RS/6000 Enterprise Server Model S70 and S70 Advanced hardware. The s70d daemon emulates an SP frame and node supervisor. It performs such tasks as: polling the hardware for changes in status, sending state changes back to Hardmon for subsequent dispersal to interested parties, accepting commands from Hardmon to change the power state, and providing an interface to the server's serial port. This daemon is started by Hardmon. There is no command line interface to this daemon.

sdrd

System Data Repository server.

sp_configd

Creates and sends SNMP traps when selected types of errors are recorded.

splogd

Logs SP hardware state changes, reports SP hardware errors, and provides a state change alert.

spmgrd

An SNMP Manager daemon that runs on the control workstation and interacts with SNMP Agents for extension nodes.

spnkeymand

Per-node key management for SP trusted services.

supfilesrv

Provides services for file collections.

switchtbld

Job Switch Resource Table Services daemon.

sysctld

Sysctl daemon; runs on the control workstation, all nodes, and other RS/6000 computers.

xntpd

Network time protocol daemon, keeps clocks synchronized across the network.

automountd

Automount daemon; automatically mounts a directory on request based on map entries.

cron

Runs shell commands at specified intervals.

errdemon

Standard AIX error daemon for recording error log information.

inetd

Provides Internet server management for a network.

named

Provides server functions for the Domain Name Protocol.

nfsd, biod, statd, lockd

Standard NFS daemons.

portmap

Provides RPC services.

qdaemon

Schedules print jobs from the enq command.

rlogind

Provides rlogin services.

rpe.mountd

Responds to client NFS mount requests.

rpestatd, rpe.lockd

Provide System V style of file and record locking with NFS.

sendmail

Routes mail for local or network delivery.

snmpd

Provides the Agent functions of the simple network management protocol.

srcmstr

System resource controller master daemon.

syslogd

Logs system messages

telnetd

Provides telnet services.

uprintfd

Constructs and writes kernel messages.

writesrv

Allows the write command to send and receive messages.

xmservd

Performance Toolbox.

ypserv

Runs on NIS servers and slaves to provide NIS services.

ypbind

Runs on all NIS clients to communicate with respective server.
