NAME

dr_daemon - dynamic reconfiguration daemon

SYNOPSIS

dr_daemon [ -a ]

DESCRIPTION

The dr_daemon is an RPC program that provides the interface to the Dynamic Reconfiguration (DR) driver, /dev/dr . The Hostview and DR applications provide the user interface to DR. See hostview(1M) in man Pages(1M): Sun Enterprise 10000 SSP Administration Commands and dr (1M)in man Pages(1M): Sun Enterprise 10000 DR Administration Commands .

OPTIONS

-a

Disable communications with the Alternate Pathing daemon. See ap_daemon(1M) in man Pages(1M): Sun Enterprise Server AP Administration Commands.

Configuration Information

The /usr/platform/sun4u1/sbin/dr_daemon RPC program name is DRPROG, its RPC program number is 300326, and its underlying protocol is TCP. It is invoked as an inetd server using the TCP transport. The UID required for access to the daemon is ssp. This UID can be a non-login UID.

The entry for the daemon in the /etc/inetd.conf file is:

300326/4  tli rpc/tcp   wait root /usr/platform/sun4u1/sbin/dr_daemon dr_daemon

The daemon's only clients are Hostview and DR. Hostview provides a GUI interface; dr (1M)is a command-line interface for non-windowing environments. The DR daemon uses syslog(3) to report status and error messages, which are logged with the LOG_DAEMON facility and the LOG_ERR and LOG_NOTICE priorities.

The dr_daemon communicates via RPC with the Alternate Pathing (AP) daemon (see ap_daemon (1M) in man Pages(1M): Sun Enterprise Server AP Administration Commands )to notify the AP software when controllers are attached to and detached from the system, or to gather information about the system configuration.
