NAME

cl_pnmd – Public Network Management (PNM) service daemon

Synopsis

/usr/cluster/bin/cl_pnmd [-d [-t [tracefile]]] [-z zone]

Description

cl_pnmd is a server daemon for the Public Network Management (PNM) module. It is usually started up at system boot time. When it is started, it starts the PNM service.

The in.mpathd(1M) daemon does adapter testing and intra-node failover for all IP Network Multipathing (IPMP) groups in the local host.

cl_pnmd keeps track of the local host's IPMP state and facilitates inter-node failover for all IPMP groups.

Options

The following options are supported:

-d: Displays debug messages on stderr.
-t tracefile: When used with the -d option, it causes all debug messages to be redirected to tracefile. If tracefile. is omitted, /var/cluster/run/cl_pnmd.log is used.
-z zone: Starts the cl_pnmd daemon in the specified exclusive-IP non-global zone. It is an error to specify a shared-IP non-global zone to the -z option.

Diagnostics

cl_pnmd is a daemon and has no direct stdin, stdout, or stderr connection to the outside. All diagnostic messages are logged through syslog(3C).

Notes

cl_pnmd must be run in superuser mode.

Due to the volume of debug messages generated, do not use the -t option for an extended period of time.

cl_pnmd is started by the pnm startup script. On the Solaris 9 OS, it is started under the Process Monitoring Facility daemon pmfd. As such, if cl_pnmd is killed by a signal, it is automatically restarted by pmfd. On the Solaris 10 OS, the Service Management Facility starts and stops the daemon.

The SIGTERM signal can be used to kill cl_pnmd gracefully. Other signals should not be used to kill the daemon.
