rbootd(1M)
NAME
rbootd − remote boot server
SYNOPSIS
/etc/rbootd [−a] [−l loglevel] [−L logfile] [logfile]
DESCRIPTION
rbootd services initial boot-up requests from HP Cluster clients and Datacommunications and Terminal Controllers (DTC/9000) over a local area network. rbootd only responds to requests from machines that are listed in the cluster configuration file or map802 file. The map802 file (a binary file) is created when a DTC is configured by dtcconfig on the host machine.
For HP Cluster clients, rbootd emulates part of the context of a client machine based on information provided by the client in the request and on information found in the cluster configuration file. Therefore, bootstrap programs and kernel programs requested by the client machine can be context-dependent files.
The following elements appear in the context emulated by rbootd for HP cluster clients:
cnode name
architecture
remoteroot
default
where cnode name is based on information found in the cluster configuration file.
The architecture field is based on the identity provided to rbootd by the booting client, according to the following table:
| Machine Type | architecture Field |
| Series 300, 400 | HP-MC68881 HP-MC68020 HP-MC68010 |
| Series 700 | PA-RISC1.1 HP-PA |
| Series 800 | HP-PA |
Options
rbootd supports the following options:
−a Append to the rbootd log file. By default, starting up rbootd truncates the log file.
−l loglevel Set the amount of information that will be logged in the log file. rbootd supports the following logging levels:
0 Log only startup and termination messages of rbootd.
1 Log all errors. This is the default logging level.
2 Log rejected boot requests from machines not found in /etc/clusterconf or /usr/dtcmgr/map802.
3 Log all boot requests.
−L logfile Specify an alternate file that rbootd should use to log status and error messages.
landevice Specify an alternate device that rbootd should use to listen for boot requests.
